How to choose a liquid level transmitter?

- Aug 07, 2020-

First, you must know your own signal output requirements. Generally, the output signal is for PLC, DCS or other instrument, so the output signal of the liquid level transmitter ULB6 must match the input signal of these instruments. Common output signals are 4-20mA, 0-20mA, 0-10V, 1-5V and other analog signals.

Second, you must know the power supply you can provide. Liquid level transmitters generally require power. Commonly used working power supplies are 24Vdc and 220Vac, and less commonly used power supplies are 12Vdc, 15Vdc, 48Vdc, 110Vac, etc.

Third, the installation method you need. The liquid level transmitter generally adopts the submersible type, threaded installation and flange installation type, and the wiring adopts the terminal connection type and is installed on the instrument.

Fourth, know the accuracy requirements. Analyze the specific situation and see if the accuracy is applicable;

Fifth, site requirements. Such as the specific application fields and scope, like power plants, chemical plants, etc.

Sixth, size requirements. The design of liquid level transmitters ULB16 is becoming more and more miniaturized, and the purpose of miniaturization is to occupy less space. Of course, users should be allowed to install intensively, and intensive installation has heat dissipation problems, so the internal power consumption must be reduced. Therefore, the value of internal power consumption should also be paid attention to when selecting.
