Instrument Configuration – Addition Options Menu
These settings affect how flow changes are displayed. They also affect how the meter controls
flow from an external control source.
Display Ave: This value acts like a filter by averaging the flow values,
which are displayed. The setting is in tenths of a second (i.e. 100 =
10.0 seconds). This only affects how the flow is displayed and not how
the meter controls the flow.
Control Mode: The control mode affects how the meter is controlled
by an external source.
Flow mode refers to standar control based on a specific flow set
point for use with standard gases.
Valve mode refers to valve position control based on % output for
carbon control gases.
Manual mode is used on meters with no valve motor for automatic
adjustment. This includes the eFlo manual meter (with a control
knob) and the eFlo In-line meter.
Ratio mode is used for specific applications involving ratio control
like mixing systems.
Altitude: –This is the altitude in feet above sea level where the meter
is installed and operating. This value affects the flow due to changes in
air density at a given altitude.
Dec. Point Override: This setting allows the flow to be displayed with a
given number of decimal point places. It is limited to 2 decimal points.
