Liquid Level Sensor,DC24V 4 20mA Throw in Type Water Level Sensors, Anti Bending 0 5m Range Depth Input Liquid Level Transmitter,6m/19.7ft Input Liquid Level Transmitter

Works as expected still after 1 year!

I've bought about ten of these over the last year or two as replacements for the maretron version - all have worked on install however at least two of them failed after calibration. The rest are doing fine. Using to measure liquid levels on water and diesel tanks on a boat using the maretron fpm100 system. I've been sent two different versions of this product and my supplied documentation was in English. The way you install this sensor is dependent on what system you are using to read it so the one star review complaining about directions should be disregarded...

I am using three of these sensors in three 2650 gallon rain water collection tanks. I wired them through a PLC and scaled the 4-20ma output for my tank size. For the money you can't beat it.

Don’t expect any instructions. This is what you get! This is the United States, so if your going to sell in the US you should have English instructions.
