I have been using the PTDevices monitoring device in my 2,500-gallon water storage tank (cistern) for several years without any issues. The set up is easy, just follow the instructions and/or YouTube videos, the service is exceptional, and the device performs extremely well. The cistern is located in Mexico, and I travel extensively but I am always informed with the status of my water level. I highly recommend the device.
Outstanding product. I have no power or WiFi where my water tank is. But I installed this system about 2 years ago and it has been working perfectly. Last night it alerted me that my tank was below its normal level and sure enough, one of the fuses for my well pump had blown. So NOW I can diagnose and fix whatever is wrong BEFORE I run out of water! Thanks, Paremtech!
I have now installed these on 3 of my tanks. It makes me sleep just a little better knowing that the tanks are monitored and able to alert me if they drop below a set amount. This also allows me to be able to transfer water between tanks without fear of running them dry. Huge game changer for me. I am using the WIFI connected tanks and have never had an issue with range. These level monitors are amazing, cannot recommend enough. 10/10!
