Guided wave radar level meter guide rod too long will have a great impact on the level measurement, this paper will illustrate the influence of guide rod too long on the level measurement, and show two actual measurement cases.
A guided wave radar level meter is an advanced technology for measuring liquid levels. It measures the level of a medium by transmitting microwave signals into the medium and receiving reflected waves. However, if the guide wave rod is too long, it can lead to increased signal energy loss, making the measurement results inaccurate.
An excessively long guide rod can lead to signal loss, resulting in insufficient signal strength, which leads to a decrease in accuracy. In addition, an excessively long guide rod may also lead to reduced penetration distance, such as errors when the measurement height is small.
Here are two actual cases to introduce the effect of long guide wave rods on level measurement. Case 1: Chemical reactor level measurement. When a chemical plant was monitoring the liquid level in a chemical reactor, they chose a guided wave radar level meter and used a long guided wave rod.
However, after using it for a period of time, it was found that the long guide wave rod would increase the signal loss, leading to a decrease in accuracy and inability to obtain accurate liquid level data.
In addition, the length of the guide wave rod limited the measurement range, so there would be errors when the measurement height was small. In this case, they shortened the guide rod to improve the measurement accuracy, thus ensuring that accurate level measurement data is always available for the production process.
Case 2: Cooling water tank in a metal processing plant. The level monitoring equipment in the cooling water tank of a metal processing plant frequently showed level errors. Upon inspection, it was found that the wave guide rod was too long resulting in insufficient signal strength and inaccurate measured level data.
To solve this problem, they shortened the waveguide rod so that the signal strength was enhanced and the level monitoring data became more accurate. Moreover, shortening the guide wave rod also reduces the cost of measurement and saves maintenance costs.
To conclude, an excessively long waveguide rod will reduce the accuracy of level measurement, so measures must be taken to solve this problem. In the actual measurement process, a suitable guide rod length should be selected, and the appropriate guide rod length should be chosen through tests and calculations to ensure accuracy and stability.
Overall, the guide rod is an important part of the guided wave radar level meter and must be fully considered and adjusted in the actual measurement process.
