4.7 Frequency output
The unit provides a frequency signal that is proportional to the volumetric flow�
Within the measuring range the frequency signal is between 0 and 1 kHz for the
factory setting�
The frequency signal is scalable:
FrEP = Frequency signal in Hz which is provided at OUT1 when the upper measured value
FEP is reached�
Factory setting: FrEP = 1 kHz = 100 %�
The measuring range is scalable:
FEP = Upper measured value at which OUT1 provides the frequency signal FrEP�
