Analyzing Radar Type Level Meters: How To Properly Set And Modify Measurement Range

When using radar type level meters, an important issue that cannot be overlooked is the adjustment of the measurement radar level meter range. Do you know how to determine and modify the range? Today, we will discuss these two key points in detail.

To accurately measure the distance between a reflector and the radar type level meter, set a reflecting element at the full-scale position of the radar level meter's beam. During the calibration process, the radar level meter range actual measurement values are compared with known reference values for debugging and calibration. Placing the reference point at the full-scale position has two main advantages:

1.Typically, the process liquid level does not reach the full scale, so the calibration process does not affect normal production.

2.At full scale, the shorter distance and higher reflection intensity allow for the use of smaller reflecting elements, reducing interference and ensuring that the reflected wave's intensity is sufficient for actual level measurements.

When using radar type level meters, there are several additional radar level meter precautions:

1.The measurement range starts from the point where the beam contacts the tank bottom. However, in some special cases, such as when the tank bottom is concave or conical, it may not be possible to measure levels below that point.

2.If the dielectric constant of the medium is low, the tank bottom may become visible at low levels. To ensure measurement accuracy, it is recommended to set the zero point at a lower height of the liquid.

3.Theoretically, the antenna position can be measured, but considering the effects of corrosion and adhesion, the measurement should maintain a distance of 100 mm from the antenna.

4.For overflow protection, a safety distance can be set and connected to the blind zone.

Accurately using radar level meters is not an easy task; it requires expertise and meticulous operation to ensure accurate measurement results. We hope today's discussion helps every user with questions about adjusting the measurement radar level meter range of radar level meters!
