Description

technical field [0001] The invention belongs to the field of instrument control, and in particular relates to a quick calibration device and method for a split-type guided wave radar liquid level gauge. Background technique [0002] In industrial applications, guided wave radar level gauge is a common measuring instrument, based on the principle of time domain reflection (TDR), radar waves run at the speed of light, and can be converted into liquid level (level) by electronic components during operation Signal. The probe emits a high-frequency pulse and propagates along the cable probe. When the pulse meets the surface of the liquid (material), it is reflected back and received by the receiver in the instrument, and the distance signal is converted into a liquid level (level) signal; its technical advantages are obvious : It can measure the continuous level of liquid, particle and slurry, and the measurement is not affected by medium change, temperature change, inert gas an...
