Ultrasonic level meter works according to the transit time

method. The ultrasonic sensor will pulse the ultrasound from

sensor to a measure medium surface and it will be reflected

back from the medium surface due to density change on

medium. Time (t) taken for an ultrasound travel from sensor

and back to the sensor are proportional to the travelled

distance (D). Transmitter detected the time (t) and calculated

the distance (D) according to the know speed of sound (c).

The formula; D = c •t/2

To determine the medium level (L), the sensor installation

height (H) is set in parameters setting. Therefore, it can

calculate the medium level as follows:

The formula; L = H – D

Since speed of sound through air is affected by changes in

temperature, the ultrasonic sensor has integrated a

temperature sensor to improve accuracy.
