3.2 Linear (Pulse) Meter Overview
The module typically receives the pulse count and pulse frequency values from a
high-speed counter module. The module uses these values to perform
calculations.
You can configure the primary input to be used for volume calculation. You can
configure it as Pulse Count or Pulse Frequency.
3.2.1 Primary Input = Pulse Count
If you select Pulse Count as the primary input, the module uses the pulse count
value transferred through the backplane as the primary input for volume
calculation. In this case, the pulse frequency will be used for flow rate calculation
only.
3.2.2 Primary Input = Pulse Frequency
If you select Pulse Frequency as the primary input, the module uses the pulse
frequency value transferred through the backplane as the primary input for both
flow accumulation and flow rate calculation. The pulse count value is ignored by
the module.
