    Possible Causes

    Possible Corrective Actions

    hiPr (High Pressure Factory Alarm)

    Inlet pressure is above the max inlet pressure for the meter.

    Decrease regulator pressure below the usable range of the sensor indicated on the calibration certificate.

    unPr (Under Pressure Factory Alarm)

    Due to low pressure based on factory-specified values, meter is unable to reach setpoint. Alarm is only active in Flow Control Mode with a setpoint above 0.

    Increase regulator pressure.

     

    Verify all upstream solenoids and/or ball valves are open.

    Shut (Shut Factory Alarm)

    Flow rate is below accuracy threshold of 10:1. Alarm is only active in manual meters. This is a warning that flow rate accuracy is not guaranteed.

    If a zero flow is required, make sure the knob is fully shut, as a false zero could be displayed.

    HiLM (Hi Limit Factory Alarm)

    Valve has achieved maximum allowable position.

    Perform a Max Tare at desired valve position.

     

    Verify inlet pressure is high enough to reach setpoint or desired flow rate.

    Comm (Internal Communcations Failure)

    Incorrect internal connections; Damage

    Check internal wiring.
