How To Ensure The Measurement Accuracy Of 80g Radar Level Meter?

80g radar level meter is a key equipment widely used in many industries, including coal, steel, metallurgy, cement, electric power, semiconductor, water conservancy, environmental protection, coal chemical industry, petrochemical industry, food and medicine and other industries. However, when measuring media level, you may encounter accuracy inaccuracies. Let's take a look at the factors that affect Radar measurement accuracy and their solutions.

 

 

1. When performing Radar level measurement, the impact of the power of the emitting electromagnetic wave signal source on Radar measurement accuracy must be considered.

2. Liquid level fluctuations or foam scattering of the measured medium will cause signal weakening, so it is necessary to increase the power of the signal source or use a waveguide to enhance the signal.

3. It is necessary to use a powerful microprocessor for complex signal processing. At the same time, the 80g radar level meter should try to contain obstacles in the tank when installing.

4. The radar level meter should be installed so that the electromagnetic waves emitted by the antenna are perpendicular to the liquid surface of the measured medium and receive as much liquid surface reflected waves as possible.

5. When measuring the top of the tank, a certain distance should be maintained to prevent the measured medium from being corrosive to the antenna.

6. It is necessary to choose antennas of different shapes according to different working conditions to avoid the influence of interference objects on the tank wall or inside the tank. It is recommended to use a waveguide to reduce interference echoes and enhance Radar measurement accuracy.

 

7. The 80g radar level meter may have the following faults:

a. Crystallization of the probe or bell mouth is easy to occur, especially in low-temperature environments.

Treatment method: Remove crystals and clean with acidic cleaning solution; use appropriate heat tracing or air blowing to extend the crystallization time.

b. The interference is large, resulting in false liquid levels.

Treatment method: Adjust the dielectric constant setting to reduce interference echoes; strengthen shielding and grounding to reduce interference sources and increase Radar measurement accuracy.

c. Although the height value of the radar level gauge is a fixed value, if the original data measurement is incorrect, the DCS system interface display may be inaccurate. It is recommended that when conditions permit, accurate radar altitude measurements should be made on the tank.
