Flange ultrasonic level meter is based on the Time-of-Flight principle. A sensor emits ultrasonic pulses, the surface of the media reflects the signal and the sensor detects it again. The Time-of-Flight of the reflected ultrasonic signal is directly proportional to the distance traveled. With the known tank geometry the level can be calculated. Flange Ultrasonic Level Meter Advantages Non-contact, maintenance-free measurement. Measurement unaffected by media properties, like dc value or density. Calibration without filling or discharging. Self-cleaning effect due to vibrating sensor diaphragm. Flange ultrasonic level meter application Flange Ultrasonic level meter with ultrasonic level sensors provides continuous, non-contact and maintenance-free level measurement of fluids, pastes, sludges and powdery to coarse bulk materials. The measurement is unaffected by dielectric constant, density or humidity and also unaffected by build-up due to the self-cleaning effect of the level sensors. Flange Ultrasonic Level Meter Installation 1:Keep Ultrasonic Level Transmitter perpendicular to liquid. 2:The transducer should not be mounted too close to the tank wall, the bracket can cause strong false echoes 3:Mount the transducer away from the inlet to avoid false echoes. 4:The transducer should not be mounted too close to the tank wall, the build-up on the tank wall cause false echoes. 5:As is illustrated by the figure on the below, the transducer should be mounted on the top of guide tube to prevent the false echoes from turbulence and foam. The guide tube should come with a vent hole at top of the tube to allow the liquid vapor go out of the tube.
