measuring instrument. Since it does not come into direct contact with the liquid in the tower or tank, there is no liquid erosion and the failure rate is low. At the same time, when installing the instrument, there is no need to clean the tower or tank, and it can be directly installed in a good location outside without affecting industrial production. The characteristics of Ultrasonic liquid level meter, such as non-contact, few interference factors, low price and convenient use, make it widely used in liquid level measurement in the fields of petroleum, chemical industry, farmland water conservancy, etc., and it is especially widely used in water treatment and automatic control systems.

1. When installing ultrasonic

2. Make sure that the probe surface is perpendicular to the measured liquid surface. At the same time, it is necessary to ensure that there are no obstacles in the area radiated by the ultrasonic beam emitted by the Ultrasonic liquid level meter probe, and the ladder, limit switch, pipeline, etc. in the tank should be avoided. Under normal circumstances, the diode of the transmitter will flash, and when the echo is received, a clicking sound can be heard near the sensor.

3. Ultrasonic waves are not very resistant to electromagnetic interference and are easily affected by nearby electrical equipment. Therefore, the signal line of the

4. If the signal line, especially the joint, is damp, it will also cause signal disorder, so the signal line should be kept dry. When the signal line must go through the cable trench, the signal line should be laid on the cable trench bracket.

5. To prevent poor contact of the signal line of the
