In daily maintenance, you can use a PC (with MAT software) to observe the reflected wave curve remotely. For interference waves that may be newly generated later, you can use the level gauge to identify false waves to remove these interference reflected waves.
Influence to ensure correct measurement.
能否准确丈量，依靠于反射波的信号。 When it is installed, attention should be paid to whether the radar level gauge can accurately measure, depending on the signal of the reflected wave. If the selected installation location, the liquid surface can not reflect the electromagnetic wave back to the radar antenna or in the range of the signal wave
There are interfering objects reflecting interference waves to the radar level gauge. The radar level gauge cannot accurately reflect the actual liquid level.
是利用雷达技术测量物料物位的仪表。 Radar level gauge is an instrument that uses radar technology to measure the level of materials. The meter transmits and receives radar waves of a specific frequency and reflects after encountering an object. The space between the meter and the material is calculated based on the round-trip time of the radar wave.
The department has the height of the entire silo set in advance. The meter calculates the actual height of the material and displays and outputs the corresponding signal.
Radar is free of noise and is mainly composed of electronic components and antennas. It has no moving parts and has very few failures during use. 的喇叭口或天线上 The problem encountered in use is that some volatile organic substances in the storage tank will be on the horn or antenna of the radar level gauge .
Crystallization, as long as they are checked and cleaned on schedule, the maintenance is small.
Pay attention to the following points during installation:
1. The stirring valve in the tank, the adhesion on the wall of the tank, and the diameter and other objects, if it is within the signal range of the radar level gauge, it will produce interference reflected waves, affecting the level measurement. When installing, choose a suitable installation location to avoid interference from these factors.
2. The axis of the radar level gauge antenna should be perpendicular to the reflective surface of the liquid level.
3. For the measurement of the liquid level of a container with a large liquid level fluctuation, a liquid level meter with a bypass pipe can be used to reduce the effect of the liquid level fluctuation.
4. The horn of the horn-type radar level gauge should exceed the inner surface of the mounting hole by a certain interval (> 10mm). The antenna of the rod level gauge should protrude from the mounting hole, and the length of the mounting hole cannot exceed 100mm. For round or oval
Round containers should be installed at a distance of 1 / 2R from the center (R is the radius of the container). They should not be placed at the center of the top of a round or oval container. Otherwise, multiple reflections of radar waves on the container wall, Gathered in the middle of the top of the container,
The formation of a strong interference wave will affect the correct measurement
