Waveform Select (S10): This DIP switch is set to match the transmitter output waveform.
Frequency Range (S9): Set to greater than the maximum expected frequency input from the
transmitter. If S10-5 is set to X2 position, the frequency is multiplied by 2, cutting the
frequency range switch by 1/2.
If S10-5 is on (Xl):
Frequency (Hz) = Maximum flow rate (units/min) x K-factor (pulses/unit)
60
If S10-5 is off (X2):
Frequency (Hz) = Maximum Flow Rate (units/min) x K-factor (pulses/unit)
30
The K-factor can be found on the Flow Meter K-factor Table or calibration sheet.
The voltage out of the frequency to voltage converter is determined by:
Volts = Frequency x 10
S9 Frequency Range
This calculation will be necessary for setting up the output range and span controls.
