When the ultrasonic liquid level meter is working, high-frequency pulse sound waves are emitted by the transducer (probe) and are reflected by the surface of the measured object (water surface). The refracted reflected echo is received by the same transducer (probe) and converted into an electrical signal. The time between pulse transmission and reception (the movement time of the sound wave) is proportional to the distance from the transducer to the object surface. The relationship between the sound wave transmission distance S, the sound speed C and the transmission time T can be expressed by the formula: S= CⅩT/2

When installing an ultrasonic liquid level meter, the blind zone problem of the ultrasonic liquid level meter must be considered. When the liquid level enters the blind zone, the ultrasonic transmitter cannot measure the liquid level. Therefore, when determining the measuring range of the ultrasonic liquid level meter, a margin of 50 cm must be left. During installation, the transmitter probe must be about 50 cm higher than the maximum liquid level. Only in this way can the accurate monitoring of the liquid level and the safety of the ultrasonic liquid level meter be ensured.

In actual use, due to poor installation considerations, the liquid level gauge was submerged in water, causing the liquid level gauge to be completely damaged.

Low price, small size and light weight, it can be used for non-contact level measurement of liquids and bulk solids in food, chemical, semiconductor and other industries, and can be used for remote level monitoring and pump control.

Attention should be paid to the mechanical installation: the installation should be perpendicular to the surface of the object to be measured, avoid being used to measure objects with foam properties, and avoid being installed at a distance less than the blind zone distance from the surface of the measured object (blind zone: each product will have a standard, which will be known with the product). Consideration should be given to avoiding blocking materials from meeting the filling mouth and container wall. When detecting large solid objects, the probe orientation should be adjusted to reduce measurement errors.
