Water level measurement 4~20mA RS485 Stainless Steel Water tank Level Sensor for Rivers and Lakes
The background
I have been posting few updates in this forum where I listed the options I was considering for water level measurement in my rainwater tank. I somehow strongly accentuated the ultrasonic method of measuring but never actually implemented it as the price of these sensors kept this item low on the priority list. Until I found this – The pressure based water level sensor. Some time ago I noticed these products already, but the ones I was looking at were not suitable for Loxone, these were with current output (instead of voltage), which would require additional HW converting it, not talking about space requirements in the cabinet, and so on. But now this is different.
Level sensor
Let’s have a look at the level sensor I purchased. It has robust stainless steel body, it can be powered by 9-36VDC and the output is 0-10V! Damn! Why haven’t I found this earlier
