Questions regarding the selection of level gauges
Thread Content
Liquid level PID control is required for an intermediate tank; what type of level gauge would be suitable? I have considered that the output signal of a magnetic flap level gauge is not a continuous signal, and I’m not sure whether PID control is possible. Those with experience, please share your insights. Thank you!
Level transmitter; if automatic control is desired, it can be combined with valves and similar components to form a control circuit
Only by specifying the medium, pressure, temperature, and actual operating conditions can instrument selection be carried out.
The medium temperature, pressure, density, viscosity, corrosivity, crystallization status, installation location, etc., of the intermediate tank need to be specified; otherwise, it will be a random choice.

If magnetic flip switches can be used, then there’s no need for concern; they can also generate a continuous 4–20mA signal, so they can be used for control purposes without any problems. It’s just that their precision isn’t that high

What was said on floors 3 and 4 is correct. Only by knowing the physical and chemical properties of the medium as well as the operating conditions can a level gauge and control valve be selected.
Environmental conditions, operating status, requirements, etc
