0.5 seconds or the vortex shedding period for frequencies less than 2 Hz.
The pulse output is an externally powered 2-wire transistor switch type output.
This output can be configured using any applicable configuration device to select any
one of three types of pulse outputs: raw pulse, rate pulse and total pulse.
Raw pulse: This is the vortex shedding frequency directly passed through providing an Raw pulse: Raw pulse: Raw pulse:
instantaneous, non dampened frequency output
Rate pulse: The frequency of this output is a 50% duty cycle pulse output with a Rate pulse:
Rate pulse: Rate pulse:
frequency range of 0...10, 0...100 or 0...1000 Hz, proportional to zero flow to the full
range flow rate/upper range value (URV).
Total pulse: The frequency of this output is also a 50% duty cycle pulse output that is Total pulse:
Total pulse: Total pulse:
configured to provide a pulse when a determined volumetric/totalized unit has flowed
through the meter.
Isolated 2-wire transistor switch
Applied voltage: 5...30 VDC
Maximum "ON" state voltage drop: 1.0 VDC
Maximum "ON" state current: 20 mA
Reverse polarity protected
