Release date:2024年01月22日 Article author:SKE Reading quantity:105

Radar level gauge, as a non-contact liquid level measurement device, has been widely used in a variety of industries. Especially in filtered water measurement, its unique advantages are fully reflected. Below, we will delve into the working principle, advantages, scope of application and practical applications of radar level gauges.


1. Working principle of radar level gauge

Radar level gauges work based on the propagation principle of electromagnetic waves. It transmits microwave pulses of specific frequencies to the liquid surface. When these pulses encounter the liquid surface, they will be reflected back based on the characteristics of its surface reflection and received by the receiving antenna. By measuring the time difference between transmission and reception, combined with the velocity of the electromagnetic waves in the air, the exact height of the liquid level can be calculated.


2. Advantages of radar level gauge

Non-contact measurement: No direct contact with liquid is required, effectively avoiding corrosion and contamination problems during long-term use of the equipment.

High-precision measurement: Due to its advanced signal processing technology, it can achieve centimeter-level measurement accuracy.

Strong adaptability: can work in various harsh environments, such as high temperature, high pressure or corrosive environments.

Easy installation: No need to drill holes in the tank, reducing installation workload and potential safety risks.

Real-time monitoring: It can provide real-time liquid level data, convenient for staff to monitor and manage.


3. Application scope of radar level gauge

Radar level gauges are suitable for various types of liquid storage containers, including round, square or special-shaped tanks. In filtered water measurement, radar level gauges are widely used in reservoirs, water towers, sewage treatment plants and other occasions.


4. Application cases of radar level gauge

In order to demonstrate the application effect of radar level meter in filtered water measurement, we selected a practical case for analysis. The case is a water treatment plant located in China, the plant uses multiple filter tanks to treat domestic sewage. Each filter tank has a capacity of 500 cubic meters. The water in the filter tank undergoes sedimentation, filtration, disinfection and other processes and ultimately to meet the water standards. In order to improve the efficiency of water treatment, save water resources and ensure the safety of water quality, the plant decided to use radar level meters to monitor the level of the filter tanks.

The plant has installed a radar level meter on the top of each filtration pool, which transmits the level data to the central control room through wireless signals for real-time monitoring and analysis by professional staff.

Through the radar level meter, the plant can accurately understand the change of water level in each filtration pool, adjust the flow rate of incoming and outgoing water in time, and keep the filtration pool in the best working condition. At the same time, through the radar level meter, the plant can find out the abnormal situation of the filtering pool in time, such as the water level is too high or too low, the water quality is deteriorating, etc., and take measures in time to avoid wasting or polluting the water resources. Through the radar level meter, the plant's water treatment efficiency has been improved by 20%, water resources have been saved by 15%, and water quality safety has been guaranteed.


5. Summary

Radar level gauge is an advanced liquid level measuring instrument. It is widely used in filtered water measurement and can provide efficient, accurate and safe liquid level monitoring solutions for water treatment plants. Radar level gauge is an ideal choice for filtered water measurement. It can improve water treatment efficiency, save water resources, and ensure water quality safety.
