Pressure Transducer Submersible Level Transducer,4-20MA Digital Water Level Display Meter Intelligent Pressure Controller Light Column Display,6m Cable Liquid Depth Level Meter Sensor

I have installed these in the Water Business Stores I build for my customers. While the manual might be in Chinese that comes with the device, the online manual available is in English. I would love to find this as 120 VAC or better yet 24VDC powered. SPDT relays would be nice, if they would use some of the terminals that are for sensors we don't need since this company includes the correct one. I add an 8 relay module that Amazon sells for less than $10.00. Very flexible and works reliably. My customers only need to know that they can change the levels that the switches actuate at, and the levels that reset it, there are 4 of these switches, that can be set to turn on at increasing to the level or decreasing to the level. You can adjust the bar graph to go full scale for the range of 4-20 ma your tank level produces. I bought two more today just to keep as stock.

Not a single word of english in the manual, chinese only. 220V, no real support at all. Stay away
