How can Water Level Monitoring Systems make homes smart?

IoT devices such as door bell cameras, motion sensors, light switches, and sockets are revolutionizing our homes and lives beyond what we could have imagined. Our favorite innovation, smart water level monitoring systems, is bringing convenience, cost savings, and peace of mind to our homes. It’s also a growing trend that people want to contribute to water conservation strategies for positive climate impact as well as cost savings. Smart water level monitoring systems are helping people make informed decisions, save water, prevent unnecessary water deliveries, and alerting users to high and low alerts preventing floods and costly outages.

What is a water level monitor? It consists of a sensor device which automatically detects the level of water inside any tank. The most common sensors are pressure-based, ultrasonic, or floats. The data from the level monitor can be collected into a graph and always provides data for the user to make decisions based on.

So how can a smart water level system for your cistern or well help you? Continue reading to explore the technology and benefits behind smart water level systems for your cistern, sump, chemical tank, etc!

How do Water Level Monitoring Systems Work?

Water level monitoring systems can work in a variety of ways such as measuring liquid pressure, using floats or ultrasonic sensors to detect the height of the water. The sensors then take this captured data and transmit it to the control unit.

For the PTLevel, that means the Transmitter reports to the Receiver and then to the Cloud. First, it measures the water pressure and compares that to the atmospheric pressure. Then transmits that level data to the Receiver up to 1 km away. Then the Receiver sends that data to the cloud via your WiFi signal and your secure online portal converts that raw data to a tank percentage. With the tank percentage you can make informed decisions, review the percentage trends in the history graphs, decide when to best conserve water, and contact your water delivery provider for a water delivery.

What are the Benefits of Water Level Monitoring Systems for Homeowners?

Water level monitoring systems for cisterns, wells, sumps, chemical tanks, rain water harvesting systems, and ponds have a slew of benefits! Let’s review some of the most common benefits below:

Peace of Mind

Arguably the top benefit of water level monitoring systems is the peace of mind that comes with knowing if and when you’ll run out of water. Or, if you’re monitoring a sump pump hole for high levels, is the peace of mind knowing you’ll be alerted before your basement floods!

Recently (January 2024), one of our customers was monitoring their sump pump hole and knew before leaving for work that their sump pump was “sounding off”. The pump was supposed to kick in when their PTLevel Water Level Monitor was indicating around 75%, and stop when the sump was around 25% empty. Their alerts were set to 85% and 20% – so they would know when the sump was not operating within the desired range. Sure enough, they received a text alert indicating that the sump went below 20%! They left work to immediately go and investigate and found that the sump pump wasn’t kicking off. Getting that notification prevented the pump from running for hours while no one was home.

Water Conservation

A great advantage of water level monitoring systems is their capacity to create visual representations of water usage, which facilitates informed decision-making regarding water conservation efforts. This capability not only aligns with climate objectives but also enables users to identify and mitigate wasteful water practices. Also, for rainwater harvesting, the ability to analyze water collection trends proves instrumental in optimizing resource management strategies.

Remote Monitoring

Smart Water Level Monitoring introduces an unparalleled capability: remote water level monitoring. This advancement is particularly advantageous for vacation property managers operating off-site, individuals with inconveniently located cisterns and tanks, and those with mobility limitations hindering access to their water storage systems. Through seamless access to their application interface, both individuals and businesses gain immediate access to comprehensive and current water level data, including history graphs and low or high level alerts without having to be on-site. All of the water data is conveniently accessed via the cloud!

Leak Detection

Just like the story of the sump pump failure (under “Peace of Mind”), receiving early warnings of water trouble is priceless. By using a smart water level monitor, you gain insights into your typical water usage and you can start understanding your water trends to detect problems early. Whether it’s leaky faucet outside, a toilet that get stuck running, or a bigger problem like a crack in your tank. Detecting water leaks can happen a variety of ways, but typically it would be an actual low level notification or a trend you notice in your history graphs depending on the circumstances.

Many PTLevel water level monitor customers set their reporting settings on their device to “aggressive” for the first few weeks to really dive into the water usage data available. After they’ve collected the data, they turn the reporting settings down in order to conserve battery life on their device. You can adjust all power settings as often as you wish by simply logging into your account.

Cost Savings

In additional to identifying leaks and reducing wasteful water usage, you can achieve other water savings by preventing wasteful water deliveries. You can schedule your water deliveries for when you actually need water without guessing by relying on data from your smart water level monitoring system. More than that, you can even share your water level data with your delivery company and they can receive alerts to complete a water delivery at the level you decide!


As you can see, there are many benefits to a smart water level monitoring system including cost savings, leak detection, accessing water level data remotely, and peace of mind.

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 (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:


  1. 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.
  2. 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!
  3. 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!)
  4. 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.

  1. 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.
  2. 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:


  1. 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.
  2. Easy Installation: These sensors are generally easier to install compared to pressure sensors, as they don’t require direct contact with the liquid.


  1. 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.
  2. Cost: While ultrasonic sensors offer unique advantages, they can be more expensive than pressure sensors, which may influence the decision-making process.
  3. 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).
