Guided wave radar level gauges are used to measure liquid levels
Thread Content
Our company’s methanol tank is equipped with a guided wave radar level gauge (with a cable length of 18.2 meters). Due to the insufficient verticality of the guided wave tube, the lower part of the cable comes into contact with it; therefore, asbestos sheets are placed on the cable to help maintain its position. Will this affect the operation of the guided wave radar, and can it ensure accurate measurement of the actual liquid level? I would like to ask everyone.
It’s not suitable to use waveguides for such long cables; they can be completely eliminated. The formaldehyde tank we use has only ropes, no waveguides.
The methanol tank has a floating disk, and a waveguide must be installed.
It won’t have an impact; there is usually a dead zone
It will be problematic to measure when the liquid level is below the asbestos board, that is, the dead zone mentioned by Teacher 4as.
