Principle:

Intelligent liquid level sensor is a set of liquid level measurement, display, output, control in one of the intelligent digital display measurement and control products. The product is fully electronic structure, the front end of the isolation membrane filled oil piezoresistive sensor, by high precision A/D conversion, microprocessor operation processing, field display, and output one analog and two switch. The intelligent digital sensor is flexible in use, simple in operation, safe and reliable.
