Regarding radar level detectors
Thread Content
Our company has recently started a project that involves the use of radar level detectors. After three days of operation, problems were detected. The most critical issue is that these detectors are accurate at times but not at others; especially during critical moments, they fail to give accurate readings, which is really frustrating. We would appreciate it if experts could share their experiences with these devices and offer some recommendations. Or experience sharing on its use.
It might be related to fluctuations in the liquid level or an improper installation location! Installation instructions 1: Keep a distance of 1/6 of the tank’s diameter from the tank wall, with a minimum distance of 200 mm. 2 cannot be installed above the feed inlet. 3 cannot be installed in the center position; if placed there, multiple false echoes will be generated, and these interfering echoes can cause the signal to be lost. 4 If the distance between the instrument and the tank wall cannot be maintained, the medium on the tank wall will adhere, causing false echoes; false echoes should be stored during instrument calibration. Measurement Conditions and Precautions 1. The measurement range starts from the point where the beam touches the bottom of the tank; however, in special cases where the bottom of the tank is concave or conical, measurement cannot be carried out when the liquid level is below this point. 2 If the dielectric constant of the medium is low, the tank becomes visible at low liquid levels; to ensure measurement accuracy, it is recommended to set the zero point at a height of C. 3 Theoretically, it is possible to measure the position at the tip of the antenna, but considering the effects of corrosion and adhesion, the end value of the measurement range should be at least 100 mm away from the tip of the antenna. 4 For overflow protection, a safety distance can be defined and added to the blind area. 5 The minimum measurement range is related to the antenna.
