Description

Technical field [0001] The invention belongs to the field of metering measuring devices, in particular to a calibration device for a radar level gauge. Background technique [0002] The working principle of the radar level gauge 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 by electronic components. The probe sends out high-frequency pulses that travel at the speed of light in space. When the material surface is reflected back, it is received by the receiver in the instrument, and the distance signal is converted into a level signal. However, in order to ensure the accuracy of the radar level gauge during use, it is necessary to calibrate the radar level gauge regularly. However, it is difficult to determine the actual height of the liquid level due to the direct calibration of the liquid level. Inaccurate, the radar level gauge is taken out and calibrated with th...

Problems solved by technology

However, in order to ensure the accuracy of the radar level gauge during use, the radar level gauge must be calibrated regularly, but it is difficult to determine the actual height of the liquid level due to the direct calibration of the liquid level, resulting in calibration Inaccurate, and the radar level gauge is taken out and calibrated with the external environment. Although the calibration result is accurate, the operation is complicated and time-consuming, and the external environment is quite different from the environment inside the tank. there will be errors
