The Flow-PR Simulator Board has all the features of the Flow-STD board and also includes the following additional features :
- Directly receives the Open Limit Switch of the Meter Outlet and Prover Inlet valves
- Disables the pulse outputs when both valves are closed
- Routes the 'A' pulse train to terminals when the Prover Inlet Valve is not closed (open limit switch active). These terminals can be Daisy-chained to the Prover Board for use in proving operations
- The Yellow LED is illuminated when either of the valves is open (flow output enabled)
- The Orange LED is illuminated when pulses are available at the terminals for Proving.
