Basic Configuration
The Basic Configuration page displays current basic parameter values and provides the ability to set, select, and reset values. The parameters are described in more detail below.

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) |
