Posted on November 30, 2023November 30, 2023 by parem_admin

A Comparative Analysis of Pressure and Ultrasonic Sensors for Liquid Measurement

In the realm of liquid measurement, selecting the appropriate sensor is crucial for accurate and reliable results. We’ve put together a comparative analysis of pressure sensors and ultrasonic sensors used for liquid level monitoring and measurement. We hope the details on advantages and considerations are helpful as you plan your liquid level management. Among the myriad options available for liquid level measurement, pressure sensors and ultrasonic sensors stand out as two prominent contenders. This article aims to provide a comprehensive comparative analysis of these sensors, aiding readers in making an informed decision based on their specific application requirements. (Spoiler alert – we think pressure sensors, especially the PTlevel, win!)

Pressure Sensors

Benefits: Provides greater accuracy, cost-effective, can handle environmental extremes, low maintenance

Ultrasonic Sensors

Benefits: Non-contact with liquid, easy installation

Pressure Sensors (like the PTLevel):

Pressure sensors operate on the principle of detecting the force exerted by a liquid on the sensor element. These sensors excel at measuring liquid depth, finding widespread application in tasks such as monitoring tank levels, overseeing industrial processes, tracking cistern levels, monitoring septic and holding tanks, and managing rainwater harvesting systems. Here are some key advantages and considerations when opting for pressure sensors:

Advantages:

Accuracy and Precision: Pressure sensors exhibit remarkable accuracy and precision, particularly in applications where precise pressure measurements are essential. The PTLevel uses a 0kpa-100kpa sensor with an accuracy of 0.096kpa per bit, which is about 9.78mm of resolution.
Cost-Effectiveness: In many cases, pressure sensors are more cost-effective than their ultrasonic counterparts, making them a preferred choice for budget-conscious projects. And in every case we can find, the PTLevel beats the price of comparative systems with ultrasonic sensors!
Reliability in Specific Environments: Pressure sensors perform well in environments with challenging environmental conditions, such as high temperatures, freezing temperatures, or corrosive substances. Condensation, frost, and high humidity are not a concern for pressure sensors. (Yes, the PTLevel is also chemical resistant, weather resistant -40°C to 100°C temperature range, and built by Canadians for tough North American winters, making it ready to handle your most challenging environment!)
Low Maintenance: Pressure sensors require very little, or easy maintenance to operate accurately. For instance, pressure sensors sometimes have to have their “pressure” calibrated or reset. In the case of the PTLevel, we recommend seasonal maintenance to reset the air-pocket.

Considerations:

Contact-Based Measurement: Pressure sensors require direct contact with the liquid. However, because the PTLevel is constructed with chemical-resistant materials and designed to withstand ice, snow, heat, and rain, you can confidently navigate any challenging liquid-level monitoring situation.
Installation Challenges: Depending on the application, installing pressure sensors may prove more complex than ultrasonic sensors, especially in scenarios where establishing physical contact with the liquid poses challenges. However, the PTLevel has eased this challenge by being designed for easy installation. Just connect the air pressure tubing to the pressure chamber and lower the pressure chamber into your liquid.

Ultrasonic Sensors:

Ultrasonic sensors utilize sound waves to measure the distance to the liquid surface. They are most known for their non-contact nature and are commonly employed in applications like wastewater monitoring. Here are some key points to consider:

Advantages:

Non-Contact Measurement: Ultrasonic sensors excel in scenarios where non-contact measurement is essential, preventing contamination of the liquid or potential damage to the sensor.
Easy Installation: These sensors are generally easier to install compared to pressure sensors, as they don’t require direct contact with the liquid.

Considerations:

Environmental Factors: Ultrasonic sensors may face difficulty in environments with high levels of dust, humidity, temperature fluctuations, or freezing temperatures. These factors can impact the accuracy of measurements. As soon as the sensor gets covered in dust, condensation, or frost, it can no longer provide accurate measurements.
Cost: While ultrasonic sensors offer unique advantages, they can be more expensive than pressure sensors, which may influence the decision-making process.
Maintenance: Dust, dirt, frost, and condensation or other debris can accumulate on the sensor, affecting the sensor’s performance. Regularly clean the sensor with a soft, lint-free cloth to ensure clear transmission and reception of ultrasonic signals.

Choosing the Right Sensor:

Ultimately, the choice between pressure and ultrasonic sensors depends on the specific requirements of the application. Factors such as accuracy, cost, installation complexity, and environmental conditions play a pivotal role in this decision-making process. Careful consideration of these factors will ensure that the selected sensor aligns perfectly with the goals of the liquid measurement system.

In conclusion, both pressure and ultrasonic sensors have their merits, and the optimal choice hinges on the unique demands of the application at hand. But we hope we’ve convinced you, the PTLevel is the perfect solution (with a 30-day money-back guarantee).

Stormwater Management; Depth and Temperature Control

Posted on November 17, 2023November 17, 2023 by parem_admin

What is a Stormwater Management System?

A stormwater retention pond, also known as a detention pond or stormwater management pond, is a artificial basin designed to capture and temporarily hold stormwater runoff and often requires depth and temperature monitoring. Stormwater runoff occurs when rainwater or melted snow flows over impervious surfaces. Runoff from roads, parking lots, and rooftops cannot be absorbed into the ground.

The primary purpose of a stormwater retention pond is to control the flow of stormwater and reduce the risk of flooding. It achieves this by temporarily storing the excess water and releasing it at a controlled rate. As a result, this allows for gradual discharge into the natural drainage system. The pond also enables sedimentation, allowing suspended particles to settle out before releasing the water.

Typically, designers of stormwater retention ponds incorporate specific features such as an inlet structure to collect runoff, an outlet structure to release controlled flows, and a pond basin that can hold water during storm events. They may also integrate vegetation into the design to help stabilize the banks and improve water quality through natural processes.

Stormwater Management Monitoring Requirements

Many cities, regions, counties, and provinces or states have their own requirements for stormwater monitoring. They require these to demonstrate that the facilities are functioning as designed. Location-specific assessments should determine the scope, approach, frequency, and extent of the monitoring program for stormwater management facility performance. This ensures that the program is not over- or under-scoped (eg. it is the right size for the site). Specifically, depth and temperature monitoring are often part of the stormwater monitoring requirements.

Stormwater Depth Monitoring

In Niagara, Ontario there is a requirement for depth monitoring at the inlet and outlet of the stormwater facility.

Stormwater quantity monitoring to verify stormwater management facility performance shall be completed as required by the Local Municipality and/or Region. Depth probes shall be installed at the inlet and outlet of the stormwater management facility to determine the operating water surface elevations within the facility during storm events. The water surface elevations shall be correlated to storage and discharge rates based upon the stormwater management facility rating curve as determined by the as-built survey of the facility after cleanout and prior to assumption by the Local Municipality or Region.
Available rainfall data shall be used to determine the corresponding return period of the storm event, for comparison and verification of the operating water levels within the facility. Where required by the Municipality and/or Region, the approved hydrologic models shall be updated to represent the as-built condition of the stormwater management facility and contributing drainage area, and hydrologic analyses completed to verify the stormwater management facility performance.
Stormwater Management Guidelines, Project No. TPB208013, Niagara Region, Page 113

To find out what stormwater monitoring requirements for depth and temperature are required in your area, reach out to your local authority.

Stormwater Quality Monitoring – Temperature

Various factors, including the temperature of the rain, the surface it falls on, and ambient environmental conditions, can influence the temperature of stormwater. Generally, when rainwater falls, it tends to be close to the temperature of the atmosphere it is falling through.

However, the temperature of stormwater can change after it comes into contact with surfaces like roads, parking lots, or buildings. The surfaces can absorb and retain heat, causing the stormwater to increase in temperature.

In our region, stormwater temperature monitoring is sometimes required at the upstream and downstream. The actual requirements are based on pre-consultation with the Region and relevant authorities.

Will a Water Filter System Reduce My Water Flow Rate?

Posted on November 2, 2023November 9, 2023 by parem_admin

Will a Water Filter System Reduce My Water Flow Rate?

In today’s world, access to clean and safe drinking water is a top priority for many homeowners. Water filter systems are a popular solution for ensuring that the water coming out of your taps is free from contaminants and impurities. However, a common concern among homeowners and business owners contemplating the installation of a water filter system is whether it will reduce their water pressure or water flow rate.

Understanding Water Flow Rate and Water Pressure

Water Flow Rate: This refers to the volume of water that flows through your plumbing system in a specific amount of time, typically measured in gallons per minute (GPM). The size of your pipes, the number of fixtures in your home, and other factors affect the flow rate.

Water Pressure: Your plumbing system delivers water to your fixtures at a force known as water pressure, typically measured in pounds per square inch (PSI). Factors like elevation, the size of your water supply pipes, and any pressure-regulating devices in the system determine the pressure.

The Impact of Water Filter Systems on Flow Rate

So will a water filter system reduce my water pressure or water flow rate? Water filter systems come in various types, such as whole-house filters, under-sink filters, and faucet-mounted filters. The impact on water flow and pressure can vary depending on the type of filter and the specific system you choose. Here’s what you need to know:

Whole-House Filters: Whole-house water filter systems are installed at the main water line and treat all the water entering your home. These systems can affect water flow rate if they have a lower GPM rating than your incoming water supply. However, the impact on water pressure is generally minimal.

Under-Sink and Faucet-Mounted Filters: These point-of-use filters are installed at specific fixtures. They are designed for smaller-scale filtration and have a more noticeable impact on water flow rate. Again, the impact on water pressure is typically minor.

Water Filter System Factors to Consider

When considering a water filter system for your home or business, there are several factors to keep in mind:

Filter Type and Capacity: Choose a filter that matches your specific needs and GPM requirements. Higher-capacity filters are less likely to reduce water flow rate.

Plumbing System: The condition and size of your plumbing system can influence the water filter on flow rate and pressure. Older or corroded pipes may experience a more significant reduction in flow rate.

Regular Maintenance: Regular maintenance and filter changes keep performance high and prevent water pressure decline.

Enhancing Your Water System with PTLevel

Combining a water filter system with a water level monitor like PTLevel can be a game-changer. The PTLevel provides real-time water level monitoring and alerts. It helps track water history and address supply issues promptly. The PTLevel can send alerts and tracks water level history. By integrating a PTLevel into your water management strategy with your cistern, pond, well, or tank, you can mitigate water outages and better manage your water usage.

Installing a water filter system in your home is a wise choice to ensure clean and safe drinking water. While there may be a slight reduction in water flow rate, the impact on water pressure is generally minimal. By selecting the right filter system, maintaining your plumbing, and considering a water level monitor like PTLevel, you can enjoy the best of all worlds – clean water, optimal water pressure, and water usage management. Make an informed decision and enjoy the benefits of a healthy and efficient water supply system for your property.

5 tips for getting the most accurate readings from a PTLevel

Posted on April 26, 2023May 10, 2023 by parem_admin

5 tips for getting the most accurate readings from a PTLevel

Long Range Wireless PTLevel monitors are an essential tool for monitoring water levels in wells, cisterns, tanks, and septics. They are incredibly useful for tracking water levels (and other liquid levels) remotely by saving time and preventing running out of water. Here are 5 tips to get the most out of your Long Range Wireless PTLevel:

First, it is essential to understand how the PTLevel works. PTLevel’s measure the pressure at the bottom of a tank via a pressure chamber which creates an air pocket and then a sensor measuring the pressure the air pocket creates compares the data to the atmospheric pressure. The pressure chamber is installed at the bottom of the tank, the transmitter then sends this data wirelessly to the receiver which displays it via your ptdevices.com account and WebApp.

Second, put in the right dimensions and calibrate. To ensure the most accurate readings from your PTLevel monitor, it is vital to enter the correct dimensions of your well or cistern into the monitor. This will ensure that the monitor can accurately calculate the depth of the liquid. Calibration is also essential to ensure that the monitor is measuring the pressure correctly. Calibration should be done after installation, and at least once a year, or more frequently if there is a significant change in temperature. It is best to calibrate your PTLevel when your tank is 100%. Your tank must be at least 25% full to calibrate. Having an accurate calibration is key to getting accurate data from your cistern or well.

Third, do quarterly maintenance. Maintenance for the PTLevel is incredibly simple; just lift the pressure chamber out of the liquid and let the pressure chamber drain. Then carefully lower the pressure chamber back in the liquid to create a new air pocket. Press the button on the transmitter and you’re all set. Quarterly maintenance is essential to keep your PTLevel monitor giving the most accurate readings from your cistern, well, or tank.

Fourth, prevent damage to the pressure tubing (commonly caused by kids, pets, lawn mowers). Damage to the pressure tubing can cause inaccurate readings from your cistern or tank. Even a small hole in the air tubing will cause low or zero pressure readings. If you have damaged your tubing or pressure chamber, reach out to our support team at support.paremtech.com.

And finally, change your batteries every 2 years. PTLevel monitors rely on batteries to function, and these batteries do not need to be changed often, only about once every 2 years. Your ptdevices.com account will indicate when your batteries are low, but it’s always good to have a new set of batteries on hand (4xAA).

Following the tips outlined above will ensure that you get the most accurate readings from your PTLevel monitor, which will help you make informed decisions about your water supply. And as always, we are ready to help if you run into problems. Please visit our support page at https://paremtech.com/need_help/!

How to clean a cistern

Posted on October 24, 2019May 10, 2023 by parem_admin

How to clean a cistern

Whether you have a plastic or cement cistern, rain water collection system, or other water tank; consistent and regular maintenance is important to maintain clean and safe water. We highly recommend you consider hiring a professional to clean your tank. They often have experience and tools that are just unmatched by the DIY’er. But if you’re up for the challenge, here are some frequently asked questions about how to clean a cistern to help you tackle the job yourself!

How to clean your cistern — Frequently asked questions on how to clean your cistern

Question: How often should a cistern be cleaned?

Answer: The quick answer is, you should be cleaning your cistern yearly. But there are a variety of factors that can affect the cleanliness of a cistern. Cisterns get “dirty” for several reasons such as hauled water vs rain water collection, different climates, and the material the cistern is made out of (cement vs plastic tank). Because of these reasons, cisterns will need to be cleaned more or less often.

Generally, if you only have water hauled to you and you are not collecting any water that isn’t already purified in some way, your cistern will need to be cleaned less often, likely every 2-3 years. This also depends on local contaminants and the material your cistern is made out of.

If you are collecting rain water, your cistern should be cleaned more often. Usually cleaning is recommended yearly but you may want to clean the cistern more frequently.

Different climates can also affect bacteria levels, sediments, and other water contaminants. Since there are too many climates to mention, it is best to do your own research on your climate to determine what contaminants may be affecting your water.

And finally, the material your cistern is made out of may also affect the frequency of a needed cistern cleaning. A cement cistern is porous, and will likely contribute to more sediment and sludge. A plastic tank will still need to be cleaned regularly and may be more prone to algae build up.

Always clean your cistern if the water starts to look, smell, or taste different.

Question: How do you clean a cistern?

Answer: The Centers for Disease Control and Prevention has a written a great article on the subject. Please visit here for their maintenance advice on cisterns and other rain catchment systems.

Step 1. Remove all debris and water from the cistern as well as debris from water collection points (eg if you collect rain water, clean your eaves troughs). This step applies to all cisterns, wells, rain water collection systems, and other liquid tanks.

Step 2. For cement cisterns, scrub the inside of the cistern with a stiff brush and a solution of 1 cup of bleach mixed with 10 gallons of water. Since bleach isn’t recommended for plastic cisterns, contact the manufacturer of your plastic cistern, or read the instruction manual on what your manufacturer recommends. Be mindful of your air quality when you’re in a cistern! Breathing in fumes from chemicals can be dangerous, and sometimes even fatal. Always read and follow all instructions on the materials you are using.

Step 3. Rinse cistern with clean, safe water, and then drain. If you still smell bleach, rinse the tank once or twice more.

Step 4. Refill the cistern with clean, safe water.

When it doubt, reach out to a professional to have your cistern cleaned. Cistern cleaning professionals have the tools, experience, and knowledge to do a great job for you! They can often use a pressure washer, reducing the need for chemicals as well as use a wet vacuum to suck out all debris and sludge. The professionals will inspect your cistern for cracks and other defects. Go to Google Maps, and then type in “cistern cleaners near me” to find some local providers.

Question: Can I use bleach in my cistern?

Answer: If you have a cement cistern, bleach is often the recommended chemical to use for cleaning, and sometimes even maintaining clean water. You can do your own research on whether you feel like bleach is the right solution for you, but here are the recommended solutions:

For cleaning: 1 cup of bleach per 10 gallons of water
For maintenance: 1 tablespoon of 5%-8.25% liquid bleach for every 100 gallons of water

Bleach is not recommended for plastic cisterns or tanks.

Question: Do all cisterns need to be cleaned?

Answer: Yes. Cisterns are designed to hold standing water and whenever there is standing water there is opportunity for bacteria growth and dirt and debris to collect. Also, wildlife will often find a way to get into water systems which can create even more risk for bacteria growth and debris that you don’t want to drink or use.

We hope some of these questions and answers were helpful to you. If you’re looking for a water level monitoring solution, please check out our products page here.
