Will rain, fog, dust, or foam affect the radar level meter?
Radar level meters use microwave signals for measurement. They have strong penetration and excellent anti-interference ability, and are much more stable than ultrasonic level meters in harsh environments. 1. Rain No significant influence.Raindrops are scattered small particles and cause very litt...Read more -
Are Radar Level Transmitters Affected by Vapor or Steam?
Radar level transmitters are generally not significantly affected by vapor or steam, which is one of the key advantages of radar technology compared with other level measurement methods. Radar level transmitters work by emitting microwave signals that travel through the air and reflect off the su...Read more
