KEM
4 Operation
The SRZ* is ready to use and does not require any special settings. After applying the supply voltage
the unit immediately provides an output signal proporional to the flow.
4.1 Evaluation
The K-factor is individually determined for each SRZ, this factor specifies the exact pulse
rate per litre. The K-factor can be found in the
calibration record,
which is supplied with
every SRZ. The calibration record contains specifications to adjust the evaluation
equipment.
The actual flow is calculated as follows:
with
Q = flow rate in litres per minute
f
= output frequency in Hz
K = K-factor of the SRZ in pulses per litre
