Function
Monitors the amplified output waveform from magnetic
sensor for flow metering.
Monitors the amplified output waveform from magnetic
sensor for discriminating between FWD and REV flow.
(Only when the double sensor is used.)
Monitors the rectangular waveform after FWD pulse wave
shaping. Timing remains the same as that of FWD and its
waveform is one before unfactored output amplification.
Accepts a simulated pulse train OVAL pulse checker Model
PC2201, or other signal source.
Input mode is PG30 mode of Model PC2201. It also accepts
pulses with levels "0": 1V max. and "1": 7-12V min. or open
collector
