Overview

The installation principle of domestic ultrasonic level gauge $r $n $r $n When the ultrasonic level gauge is working, high-frequency pulse sound waves are emitted by the transducer (probe) and reflected on the surface of the measured object (water surface). The reflected echo is received by the same transducer (probe) and converted into an electrical signal. The time between pulse transmission and reception (the motion time of sound waves) is proportional to the distance from the transducer to the surface of the object. The relationship between the distance S of sound wave transmission, the speed of sound C, and the transmission time T can be expressed by the formula: S=C X T/2

Domestic ultrasonic level gaugeInstallation principle

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

The installation of ultrasonic level gauges must consider the blind spot issue of ultrasonic level gauges. When the liquid level enters the blind zone, the ultrasonic transmitter cannot measure the liquid level. Therefore, when determining the range of the ultrasonic level gauge, a margin of 50 centimeters must be left. When installing, the transmitter probe must be about 50 centimeters higher than the high liquid level. This is the only way to ensure accurate monitoring of the liquid level and ensure the safety of the ultrasonic level gauge.
