Description

TECHNICAL FIELD

[0002] The ultrasonic liquid level meter is a digital liquid level instrument controlled by a microprocessor and is composed of three parts: an ultrasonic transducer, a processing unit and an output unit. In measurement, ultrasonic pulses are emitted by a sensor (transducer), and the sound waves are reflected by the liquid surface and received by the same sensor or an ultrasonic receiver. The sound waves are converted into electrical signals by piezoelectric crystals or magnetostrictive devices, and the distance from the sensor to the surface of the measured liquid is calculated based on the time between the emission and reception of the sound waves. Since the measurement is non-contact, the measured medium is almost unrestricted, and it can be widely used for measuring the height of various liquids and solid materials.
