Description
Overview
GAOTek ultrasonic liquid level gauges is a digital liquid level instruments controlled by a microprocessor. In the measurement, the ultrasonic pulse is sent by the sensor (transducer), and the sound wave is received by the same sensor after being reflected by the liquid surface, and converted into an electrical signal by the piezoelectric crystal.And the distance between the sensor and the surface of the liquid to be measured is calculated by the time between the emission and reception of the sound wave.Due to the use of non-contact measurement, the measured medium is almost unlimited, and can be widely used to measure the height of various liquids and solid materials.
