Application Of Water Level Indicator Ultrasonic Liquid Level Sensor in Sewage Treatment

In recent years, as environmental pollution problems have become increasingly prominent, sewage treatment has become an important issue in social development. In the sewage treatment process, liquid level measurement is a key link. In order to accurately measure liquid level, the water level indicator ultrasonic sensor meter came into being. Ultrasonic liquid level gauge has the characteristics of non-contact measurement, high precision and good stability, so it is widely used in the field of sewage treatment.

 

 

The working principle of ultrasonic level indicator is to use the propagation speed of ultrasonic waves to measure the depth of liquid. It emits a beam of ultrasonic waves. When the ultrasonic waves encounter a liquid, part of the energy will be absorbed by the liquid and the other part of the energy will be reflected back. After the liquid level meter receives this reflected ultrasonic signal, it calculates the height of the liquid level based on the time difference of the signal. This measurement method does not require contact with the liquid being measured, so it can avoid interference from contaminants on the liquid level measurement and ensure the accuracy of the measurement results.

 

In the field of sewage treatment, ultrasonic liquid level gauge has a wide range of applications. First, it can be used in sedimentation tanks in sewage treatment facilities. The sedimentation tank is a key equipment for preliminary treatment of sewage. Through the sedimentation tank, suspended solids can settle to the bottom of the sludge tank, thereby purifying the sewage. The water level indicator ultrasonic sensor can accurately measure the height of suspended solids in the sedimentation tank, and control the sludge discharge rate in the sedimentation tank based on the measurement results, thereby controlling the sewage treatment process.

 

Ultrasonic liquid level gauge can also be used in biochemical pools. The biochemical pool is an important link in the sewage treatment process. It degrades organic matter through biochemical action and purifies the organic matter in the sewage. In the biochemical pool, the progress of the biochemical reaction can be understood by measuring the height of the liquid level, so that the oxygen supply and stirring speed in the biochemical pool can be adjusted in a timely manner to maintain the stability of the biochemical reaction.

 

The ultrasonic level indicator can also be used in the buffer tank between the concentration tank and the sedimentation tank. The function of the buffer tank is to balance the flow fluctuations between the concentration tank and the sedimentation tank to ensure stable operation of the system. By using a wireless ultrasonic liquid level meter to measure the liquid level in the buffer tank, the inlet and outlet valves of the buffer tank can be adjusted in time to maintain the balance between the concentration tank and the sedimentation tank.

 

ultrasonic liquid level gauge has a wide range of applications in sewage treatment. Its non-contact measurement, high accuracy and good stability make it an indispensable tool in the field of sewage treatment. By using the water level indicator ultrasonic sensor, precise control of all aspects of the sewage treatment process can be achieved, thereby improving the treatment effect, protecting the environment, and promoting sustainable development.
