Installation Considerations for Ultrasonic Level Meters with Volatile Liquids in Closed Containers

　　Ultrasonic level meter For level measurement of volatile liquids in closed containers, what should be noted? a. The speed of sound of the gas in the container may differ from that in air; if the level meter cannot correct for the speed of sound, a certain error will occur; b. Volatile liquids may condense on the surface of the ultrasonic level meter probe, blocking the transmission and reception of sound waves, requiring the level meter to have variable power control. Our company's products can meet the above requirements and have been widely applied in practice.

　　What is the blind zone of an ultrasonic level meter? When an ultrasonic level meter emits an ultrasonic pulse, it cannot simultaneously detect the reflected echo. Because the emitted ultrasonic pulse has a certain time width, and after transmission, the sensor still has residual vibration, during which the reflected echo cannot be detected, so a short distance from the probe surface downward cannot be detected normally. This distance is called the blind zone. If the high level being measured enters the blind zone, the instrument will not detect correctly and errors will occur. If necessary, the level meter can be installed at a higher position.
