Operating Instructions for Helical Flow Meters Type SRZ8 KEM4 OperationThe SRZ* is ready to use and does not require any special settings. After applying the supply voltagethe unit immediately provides an output signal proporional to the flow.4.1 EvaluationThe K-factor is individually determined for each SRZ, this factor specifies the exact pulserate per litre. The K-factor can be found in the calibration record, which is supplied withevery SRZ. The calibration record contains specifications to adjust the evaluationequipment.The actual flow is calculated as follows:withQ = flow rate in litres per minutef = output frequency in HzK = K-factor of the SRZ in pulses per litreQ f 60K= ā
