The input type liquid level sensor works based on the principle that liquid static pressure is proportional to depth, converting pressure signals into standard electrical signals for output. The advantage lies in the wide range (from 0.5 meters to over 100 meters), which can be directly installed Continuous monitoring of liquid level height is required: Input type liquid level sensors or magnetic flap level gauges (with remote transmission function) are preferred The input type liquid level sensor is the most versatile continuous measurement choice and has the widest range.
