80G High-frequency power tank radar level meter is widely used in powder measurement in cement and power industries. The high-frequency radar level meter transmits and receives radar waves with very low energy through the antenna system. Radar waves travel at the speed of light. The operating time can be converted into a level signal by means of electronic components. A special time extension method ensures stable and accurate measurements over a very short period of time. Even under complex working conditions with false echoes, the level echoes can be accurately analyzed through the built-in microprocessor chip and special algorithm software of the high-frequency radar level gauge.
Precautions for high-frequency powder tank radar level meter installation
1. The measurement range starts from the point where the beam touches the bottom of the tank, but in special cases, if the bottom of the tank is concave or conical, the measurement cannot be performed when the material level is lower than this point.
2. If the medium is low dielectric constant when it is at low liquid level.
3. Theoretically, it is possible to measure the position of the antenna tip, but considering the influence of corrosion and adhesion, the final value of the measurement range should be at least 100mm away from the tip of the antenna.
4. For overflow protection, a safety distance can be defined to be attached to the blind zone.
5. The smaller measurement range is related to the antenna.
The measurement range is calculated from the point where the beam touches the bottom of the tank, but in special cases, if the bottom of the tank is concave or conical, the measurement cannot be performed when the level is below this point. For overflow protection, a safety distance can be defined to be attached to the blind zone. The measurement range is related to the antenna.
The installation requirements of the high frequency radar level meter in the powder tank
1. Try not to install it in the center of the jar.
2. The distance from the tank wall is 1/6 of the tank diameter, and the minimum distance is 200mm.
3. It cannot be installed above the feeding port.
Note: The measurement range is calculated from the point where the beam touches the bottom of the tank, but in special cases, if the bottom of the tank is concave or conical, the measurement cannot be performed when the bottom of the material is at this point. If the medium has a low dielectric constant, when it is at a low liquid level, the tank is low and visible. At this time, in order to ensure the measurement accuracy, it is recommended to set the zero point at the position where the low height is C. It is theoretically possible to measure the position up to the tip of the antenna, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100mm from the tip of the antenna. For overflow protection, a safety distance can be defined to be attached to the blind zone. The smaller measurement range is related to the antenna.
Recommended distance for high frequency powder tank radar level meter
(1) The wall to the outer wall of the installation short pipe: the distance from the tank wall is 1/6 of the tank diameter, and the minimum distance is 200mm. Cannot be installed above the feed inlet
(2) It cannot be installed in the center. If it is installed in the center, multiple false echoes will be generated, and the interference echoes will cause signal loss. If the distance between the meter and the tank wall cannot be maintained, the medium on the tank wall will adhere to cause false echoes, and false echoes should be stored when debugging the meter.
The correct selection of the high-frequency radar level meter in the powder tank is very important. The measurement conditions of each tank are different, and the high-frequency radar level meter suitable for the scene can be used for better use.
