How To Deal With Inaccurate Measurement Of Radar Type Level Meter?

radar type level meter is an efficient and accurate measuring instrument. radar gauge working principle is very simple and effective. Radar level meters can easily complete the measurement task by emitting microwave pulses and reflecting them back to measure the target's level signal.

 

 

However, during the measurement process, errors may occur due to various factors. These factors include internal instrument product itself as well as external environment, media and other reasons.

Internal reasons - errors caused by the radar type level meter itself

This may be caused by the user's own lack of technical skills or improper installation and use. As for the errors caused by factors such as the external environment and media, the radar level meter uses guided wave radar technology and will not be affected by environmental conditions such as temperature, pressure, humidity, etc. Therefore, most of the errors are caused by human factors.

External reasons - problems with the instrument during use

1. The dielectric constant of the liquid to be measured must be 10 greater than the liquid below before measurement can be carried out. If the difference is not large, a wave pattern will be generated, thus affecting the measurement results. In addition, if the liquid level is low, the returned signals may be superimposed, which may also lead to errors. Therefore, when using radar type level meters, you need to pay attention to these details.

2. The radar level meter has two blind areas during measurement, namely the top blind area and the bottom blind area. The top blind zone refers to the smallest distance that can be measured between the page and the upper reference point, which is about 0.4~0.5 meters; the bottom blind zone appears at the bottom of the probe, and the measurement results do not change with the change of the official liquid level in the tank. . Therefore, it is necessary to avoid measuring in these areas as much as possible to ensure the accuracy of the measurement results.

3. Excessive viscosity of the measured liquid will also affect the measurement accuracy of the radar type level meter. At this time, highly viscous liquid will adhere to the probe, hindering signal transmission, resulting in errors. In response to this situation, users need to take some maintenance measures, such as cleaning the probe regularly, to ensure measurement accuracy.

 

Radar level meter manufacturers may encounter some problems during use, but as long as they pay attention to details and perform timely maintenance, errors can be avoided. We hope that all users will pay more attention when using it to ensure the accuracy of measurement results.
