Differences between radar level gauges and weight-type level gauges
Thread Content
Help: Dear sea friends, what is the difference between a radar level gauge and a weight-type level gauge? For continuously processed solid materials, what type of level gauge is suitable?
For controlling points, continuous measurement is better done using radar or radio frequency; as for the motor that moves the weight up and down, its operation isn’t very reliable. You can find out more about the working principles of these methods by searching on Baidu
However, with radar level gauges, if the gas surrounding the antenna is dirty, the antenna is prone to getting clogged with debris, which can have a significant impact on the measurement results
Regarding the disadvantages of formal radar level gauges mentioned above, proper installation is necessary; a dust collector with good dust removal performance is required. The final solution is to have the thermal control system generate a counterwave signal to filter out interference. Like radar, RF also has its drawbacks; in my experience it’s possible to increase the density at which it can be used. The only solution in such cases is to clean it up, and there’s no problem either if the solid particles are large or of a certain size.
What was said on the 3rd and 4th floors makes sense; for environments with a lot of dust and large particles, radar is a relatively ideal solution. Some people might worry about debris getting stuck on the antenna, but this issue is easy to resolve by installing a dust cover over the antenna opening and cleaning that cover regularly. Or choose a radar level gauge with compressed air purging. The weight hammer has poor long-distance transmission, and the pulley tends to get stuck during operation. For radio frequency, when the range is large, static electricity is generated during material discharge, which significantly affects the measurement accuracy.
