Description

The ultrasonic method is a mature and economical liquid and solid solution. Provide integral and split instruments. The measuring principle is based on easy design, assembly, fast and safe commissioning, which can prolong the service life and reduce the maintenance cost. Even in harsh environmental conditions, abrasive and corrosive media are also applicable. The ultrasonic level meter transmits ultrasonic pulse, the signal reflects on the medium surface, and the instrument detects the return signal. The travel time of ultrasonic signal is proportional to the transmission distance. If the can body structure is known, the level value can be calculated. Non contact and maintenance free measurement, which is not affected by dielectric properties, such as dielectric constant or density; The self-cleaning function is realized by the vibration of the diaphragm of the ultrasonic probe without charging or emission calibration.
