Malfunctions And Causes Of Guided Microwave Radar Level Transmitter

Malfunctions and Causes of Guided Microwave Radar Level Transmitter

1. The unstable signal may be due to obstacles between the antenna and the liquid level, causing interference or reflection of the signal. To solve this problem, it is necessary to check the installation position of the Guided Wave Radar Level Gauge and try to avoid the presence of obstacles as much as possible.

2. If the signal strength is low, there may be interference between the Radar guided wave level gauge and the liquid. At this point, it is necessary to check whether the dielectric constant of the liquid matches the preset value of the instrument. If it does not match, the liquid level gauge needs to be recalibrated.

3. For situations where low viscosity liquids cannot be measured, the Guided Wave Radar Level Sensor is generally suitable for liquids with medium to high viscosity. If you want to measure low viscosity liquids, you need to choose a suitable instrument model.

4. Guided microwave radar level transmitters cannot measure gas or foam liquid because it is based on the measurement principle of electromagnetic wave signal. In this case, it is necessary to choose another type of liquid level gauge.

5. Cable faults may also cause Cable guided wave radar level gauge to malfunction. The cable may be corroded by liquid or mechanically damaged, so it is necessary to check the condition of the cable. If there is any damage, the cable needs to be replaced.

6. Signal loss may be caused by incorrect connection of the sensor to the host, poor physical contact between the guided microwave radar level transmitters and the liquid level, or signal circuit failure. In this case, it is necessary to check the connection status and physical contact of the sensor, and troubleshoot the signal circuit.

7. Signal interference may be caused by the presence of electromagnetic interference sources near the Guided Wave Radar Level Sensor head, such as high-voltage cables, strong electromagnetic fields, or other radar equipment. To solve this problem, it is necessary to minimize the presence of interference sources or relocate the sensors.

8. If the reading error of the Guided microwave radar level transmitters is large and does not match the actual liquid level, it may be caused by incorrect sensor position, changes in liquid density, or interference from substances such as dirt or bubbles on the sensor head. In this case, it is necessary to adjust the position of the sensor, pay attention to changes in liquid density, and keep the sensor head clean.
