Liquid level measurement is often treated as a simple task.

Either liquid is present, or it is not.

But in industrial refrigeration, a level switch is often the first line of defence against operational problems. Incorrect level detection can lead to pump failures, liquid carryover, unstable operation and unnecessary service calls.

That is why reliability matters.
