> Submersible liquid level transmitter
= ,
> It can be used to measure the liquid level in open containers, rivers, lakes, and wells. It has a simple structure and accurate measurement. and easy installation.
=
> The submersible liquid level transmitter consists of a stainless steel probe, a gas conduction cable and an electrical box. The probe of the transmitter is made of stainless steel and can be directly put into the liquid to be measured. The sensor chip is isolated from the medium by a stainless steel diaphragm, thus ensuring that it can measure the liquid level of a variety of media. The electrical box consists of a circuit chamber and a wiring chamber. Zero point and span can be adjusted on the circuit board.
