Background

The ultrasonic level gauge is a digital level gauge controlled by a microprocessor. In the measurement, ultrasonic pulses are emitted by a sensor (transducer), sound waves are reflected by the surface of the liquid and then received by the same sensor or an ultrasonic receiver, the sound waves are converted into electric signals through a piezoelectric crystal or a magnetostrictive device, and the distance from the sensor to the surface of the measured liquid is calculated according to the time between the emission and the reception of the sound waves. Because of adopting non-contact measurement, the measured medium is almost unlimited, and can be widely used for measuring the height of various liquid and solid materials. The ultrasonic liquid level meter consists of three parts: ultrasonic transducer, processing unit, output unit.
