Measuring the liquid level in the tank; it’s corrosive, and the ultrasonic device produces foam which causes the readings to be 0.

The simplest solution is to add an 80-100mm PVC pipe, the kind used for sewers, to the existing installation site. The length of the pipe should correspond to the depth of the tank; make sure to drill a few more pressure equalization holes on the sides. Place the ultrasonic device inside the pipe, and basically no foam will remain inside it. If you don’t believe it, feel free to contact me via WeChat: 15921738231
