Submersible Level Sensor 4-20mA, Throw-In Type Liquid Level Sensor,24V DC Input Liquid Level Transmitter,0-5M Measuring Range

Works perfect so far, I used a 4-20ma to 0-10v converter to use with my sensor on a water tank level project.

This sensor is sold under various brands by various firms. (The photo is identical on all offerings here on Amazon.) I have tried three brands, selecting only by price and delivery. We have 12 sensors installed measuring tank levels ranging from 8 to 15 feet in depth transmitting data to a PLC. We dropped them in the tank, filled them, then entered the empty and full readings as our scale. We now have fairly accurate depth measurements for each tank.These units replaced FlowLine EchoPod Ultrasonic sensors that cost ten times the price. The EchoPods continued to throw false readings (empty or full) at apparently random times during the day. These have been solid.The one page of instructions is in Chinese. However, the only item of interest is the photo showing the plus and negative wire. Any electronics tech will understand the obvious way to connect it.

I've been looking for a way to monitor the water depth in my well house for quite a while I've tried homebrew ultrasound design in the past and the depth reading seemed to drift more than I liked depending upon the weather. My test readings with the level sensor were stable and I don't expect to have the same issue with drift.

Despues de mucho tiempo desarrolando sistemas de medición de nivel de agua en tanque con sensores ultrasónicos, llegamos a este sensor. Es la mejor solución, no da problemas, mide con exactitud y no lo afecta la turbulencia en el agua que produce el agua al llenarse el tanque. Recomendado 100%

No soporta presión de 5 mts de agua

Failed after only 6 weeks of use. Two weeks after the return window.Replaced with an identical unit bought as a replacement backup. I will see how long this one will last.Very disappointed.
