The range of the sensor is 5m water level , not 1m as indicated in above specification. It is very lineair over the 0-5m level range. Working very well. I have made an analoge water level meter for a 0-1.5m waterlevel with this sensor. The circuit is very simple (just 6 components ,working very well. If connected to an analoge meter, the 4 mA start current must be compensated. Therefor I use a 2.5V stabiliser, If allowed I can post the diagram

Works very well, no comment on the product but, Adres was for the 2nd time not correct: house number missing. First time, package was send back to China, and I had to re-order. This time, I was lucky that the postman has investigated on what house number I was living, he was spending a lot of time to do so. Please inform your staff that also the house number is part of the address!!!!

Just received and tested. + Works well, radioactivity tested of an old smoke alarm with opened sensor. Measured value om 2cm distance: : 1.00 µsV/h , compared with an military device: DOM410 it gives about the same value. Average background 0.10 µsV/h -The device is rather slow, it takes +/-2min to indicate the full 1.00µsV /h. -The sound bips have very low volume,(hardly to hear ) would prefer double or triple the volume Technical : The most sensitive part is the left part of the unit, so suppose the sensor tube is on the left side
