Product operation

6.1. Measuring principle

The transducer of the ultrasonic measuring device emits short ultrasonic pulses, at 55 kHz to the measured product. These pulses

are reflected by the medium surface and received by the transducer as echoes. The running time of the ultrasonic pulses from emis-

sion to reception is proportional to the distance and hence to the level. An integrated temperature sensor detects the temperature in

the vessel and compensates the influence of temperature on the signal running time. The determined level is converted into an output

signal and transmitted as a measured value.

6.2. Product operation notes

Set up with display/configuration module

The measuring device is adjusted with the display/configuration module. The entered parameters are generally saved in the measur-

ing device, Type 8177. Optionally, parameters may also be uploaded and downloaded with the display/configuration module.

Display/configuration module

Description

The display/configuration module can be inserted into the measuring device and removed

again at any time. It is not necessary to interrupt the power supply. The measuring device is

adjusted via the four keys of the display/configuration module.
