Level measurement
Procedure
To set fill level measurement, proceed as follows:
1. Start SIMATIC Manager.
2. Create a device with measurement type "Fill level".
3. To open SIMATIC PDM, double-click on the device you have created.
Depending on whether you want to measure a height, a volume, or a mass, set the following
values.
Height measurement
To select height measurement, proceed as follows:
● Start SIMATIC PDM. Create an assignment between the pressure to be measured
(measurement range) and the fill level to be recorded (working range), by setting these
parameters:
>

>
Transducer block 1
Transmitter type:

● Create an assignment between the measured level value and the output value by setting
these parameters:
