Measuring Principle:

The sensor of the meter pulses in the direction of the product surface. There, they are reflected back and received by the sensor. The meter measures the time t between pulse transmission and reception. The meter uses the time t (and the velocity of sound c) to calculate the distance D between the sensor membrane and the product surface:ULTRASONIC LEVEL TRANSMITTER ALIT 

D=c.t/2

F: level full scale
D: distance value
H: installation height B: blacking distance

As the device knows the empty distance H from a user entry, it can calculate the level as follows:

L=H-D

An integrated temperature sensor compensates for changes in the velocity of sound caused by temperature changes.

Calibration:

Calibration Enter the empty distance H and the span F to calibrate the device.
