Installation
Introduction
The ultrasonic velocity in gas is influenced by the gas temperature,So the level meter need to detect the gas temperature at work. So the material level meter need to detect the gas temperature at work,compensation for sound velocity.
The sensor of the meter pulses in the direction of the product surface. There, they are reflected back and received by the sensor.
Advantages
High Precision 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.
 
Application
High Precision Level Meter Application
To ensure that the ultrasonic transmission to the measured ultrasonic liquid level or material surface occasion.

Installation
High Precision 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.
6:When you mount the transducer on the solid tank, the transducer must point to the tank outlet.
