Precautions for radar level gauge
1. The measurement range starts from the point where the beam touches the bottom of the tank, but in special cases, if the tank bottom is concave or conical, measurement cannot be carried out when the level is below this point.
If the medium has a low dielectric constant and the bottom of the tank is visible when it is at a low liquid level, it is recommended to set the zero point at a low height of C to ensure measurement accuracy.
In theory, it is possible to measure the position of the antenna, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100mm away from the antenna.
4. For overflow protection, a safe distance can be defined to be added to the blind spot.
5. The small measurement range is related to the antenna.
The intelligent radar level gauge is suitable for non-contact continuous measurement of the level of liquids, slurries, and particulate materials, and is suitable for large temperature and pressure changes; In situations where inert gases and volatiles are present.
The measurement method adopts microwave pulses and can operate normally within the industrial frequency range. The beam energy is low and can be installed in various metal and non-metal containers or pipelines, without causing harm to the human body and the environment.
The radar level gauge emits extremely short microwave pulses with low energy, which are transmitted and received through an antenna system. Radar waves travel at the speed of light. The running time can be converted into level signals through electronic components. A special time extension method can ensure stable and accurate measurements in a very short period of time.
Even in complex working conditions where false echoes exist, new microprocessing techniques and debugging software can accurately analyze the echoes of the material level.
