Radar level gauge belongs to the general radar level gauge, which is a measuring instrument based on the time travel principle. The radar wave runs at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits high-frequency pulses that propagate at the speed of light in space. When the pulses encounter the surface of the material, they are reflected back and received by the receiver inside the instrument, which converts the distance signal into a level signal.

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, the latest microprocessing technology and debugging software can accurately analyze the echoes of the material level.

Measurement principle of radar level gauge

Radar level gauge is a radar level gauge based on the principle of time-domain reflection (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. When it encounters the surface of the measured medium, part of the pulse of the radar level gauge is reflected to form an echo and returns to the pulse emitting device along the same path. The distance between the emitting device and the surface of the measured medium is proportional to the propagation time of the pulse between them. The liquid level height is calculated by

Measurement method of radar level gauge

It is a radar level gauge based on the Time Domain Reflectance (TDR) principle. Some pulses of the radar level gauge are reflected to form echoes and return along the same path. However, considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100mm away from the tip of the antenna. For overflow protection, a radar level gauge safety distance can be defined and attached to the blind zone. The minimum measurement range is related to the antenna. With different concentrations, foam can both absorb microwave and reflect it, but it can be measured under certain conditions. Return to the pulse transmission device.
