Parameter
Description
Set Dat/Time
Sets the date/time (real time calendar clock).
Setpoint
The current flow setpoint.
Address
The Modbus address of the device - a number from 1-247.
The device will respond to 250 universally.
Baud Rate
The baud rate for communications.
Reset Total
Resets the totalized value.
Zero Tare
Resets the zero flow rate of the meter (manual mode only).
Max Tare
Sets the maximum opening position to which the valve is
capable of driving.
Low Flow Alarm
Triggers an alarm if the flow drops below the programmed
value (0 = alarm not set).
High Flow Alarm
Triggers an alarm if the flow increases above the
programmed value (0 = alarm not set).
Low Pres Alarm
Triggers an alarm if the supply pressure drops below the
programmed value (0 = alarm not set).
Deviation Alarm
Triggers an alarm after 60 seconds if the flow PV deviates
from the flow SP more than the defined deviation (0 =
alarm not set).
Under Pressure Alarm
Triggers an alarm when the differential pressure is less
than 3” W.C. of the supply pressure (On = alarm is active).
Valve Shut Alarm
Triggers a “Shut” display when the flow is less than 10% of
the maximum flow and there is pressure available. This
alarm is used mainly on manual eFlo meters and in-line
meters to alert the user that the meter’s valve may not be
fully closed (On = alarm is active).
Max Opening Alarm
Indicates when the valve is opened to its maximum limit
(On = alarm is active)
