What is the empty mark and full mark of the radar level gauge

The radar level gauge is divided into empty mark and full mark, so what do the radar level gauge empty mark and full mark mean? Empty means no liquid; full means the highest point of the liquid level, which means that a borrower has raised all the required funds within the bidding period and is saturated and cannot continue to bid. Zero is not a target, it is set by ourselves. The empty scale value E determines the zero point, and the full scale value F corresponds to the range. Measure the actual height from the flange to the bottom of the jar and enter it. For example, a radar level gauge is installed in a project. After installation, the empty standard is 3.9 meters and the full standard is 3.5 meters. There was also no feed in the tank, and after a few hours it showed a liquid level of over 1 meter. Displays 0 after suppression. But a few hours later it showed a liquid level of more than 1 meter. Displays 0 after re-suppression. After a few hours, it was still more than 1 meter. It's definitely an empty can. If the radar outside the warehouse is about one meter away from the ground or wall and stabilized for ten seconds, no echo loss alarm will appear. Then the echo loss alarm may be due to a problem with the installation flange or riser, or the large dust in the warehouse, or the large water vapor, so that the radar wave cannot be returned after it is sent out, and an echo alarm occurs. The current output alarm may be caused by the incorrect empty or full scale data set by you, which may cause the radar to mistake the actual measurement data as over-range. Radar level gauges measure from top to bottom. At this time, how much the top of the tank should be empty is 'full', and how far below is 'zero', which cannot be determined when leaving the factory. It is necessary to adjust and determine as needed before use, that is, high-level adjustment and low-level adjustment.
