MorningSky RLM604 Radar Level Meter

      Working Principle of Chenqiong Electronic Radar Level Gauge

     Radar level gauges operate based on the echo ranging principle. Their horn or rod-shaped antennas emit microwaves toward the measured material surface. When microwaves propagate to the material surface with different relative dielectric constants, they are reflected and received by the antenna. The time difference between the transmitted and received waves is proportional to the distance between the material surface and the antenna. By measuring the propagation time, the distance can be determined. Based on the waveform of the microwaves used, radar level gauges can be classified into frequency-modulated continuous wave radar level gauges and pulsed wave radar level gauges.

     Advantages of Radar Level Gauges

1. Non-contact measurement: No direct contact with the measured liquid is required, making it resistant to corrosion and contamination by the medium. It is suitable for special environments such as high temperature, high pressure, and explosive conditions.

2. High accuracy and wide measurement range: Capable of measuring the level of various liquids with an accuracy of up to ±1mm. It is also suitable for level measurement of moving or deposited materials.

3. Strong reliability: Due to its non-contact nature, radar level gauges have a long service life and low maintenance costs.

     Application Fields of Radar Level Gauges

     Radar level gauges are widely used in industries such as petroleum, chemical, power, food, and pharmaceuticals for the measurement and control of liquid levels, interfaces, and bulk material levels. They feature easy installation and maintenance, simple operation, and a high degree of automation.

     In summary, radar level gauges utilize a non-contact principle and offer advantages such as high accuracy and strong reliability. They are suitable for measuring the level of various liquids and are widely applied in different industries and fields for the measurement and control of liquid levels, interfaces, and bulk material levels.
