8. Working Principles
During operation, the device emits a wave to the medium to be measured. The
wave reflects off the surface and moves back to the device where a transducer
calculates the distance. The distance is based on the time interval between
transmission and reception of the wave. D= (334.1+0.6t) x T/2, where the D = the
transmission distance; t =temperature; and T= transmission time.
With 4~20mA output, it can be connected to the PLC, DCS and SCADA systems. In
addition, it is also equipped with exclusive PULSE and AGC (Auto Gain Control)
echo tracking technology to ensure accuracy and precision even in the harshest
environments.

10. Installation
10.1 Mounting
➢Sensor should be mounted 1/3 the diameter of the vessel from the vessel wall
➢Unit should never be closer than 300mm (12) to the liquid surface
➢Install the ultrasonic sensor horizontally on the top of the tank.
➢Screw in the 1-inch screw of the sensor to install it.
➢Install the sensor so that the sensor surface is parallel to the surface of the
liquid.
➢If the installed sensor is closed to the side wall of the tank or an equivalent,
➢unnecessary reflection wave is detected and the incorrect measurement
occurs.
➢Do not use unnecessary force to screw in the sensor.
➢Prevent the sensor from the direct sun.
➢Do not install the multiple sensors in the same tank.
➢(Incorrect measurement occurs due to the mutual interference.)
