Total Mode
Mode that determines when the Total Limit HART Alert will activate.
> High Limit – The HART Alert will activate when the measured net total
exceeds the Total High Limit set point.
< Low Limit – The HART Alert will activate when the measured net total
falls below the Total Low Limit set point.
In Range – The HART Alert will activate when the measured net total is
between the Total High Limit and Total Low Limit set points.
Out of Range – The HART Alert will activate when the measured net total
exceeds the Total High Limit set point or falls below the Total Low Limit set
point.
Total High Limit
Set the net total value that corresponds to the high limit set point for the Flow
Limit 1 alert.
Total Low Limit
Set the net total value that corresponds to the low limit set point for the Flow
Limit 1 alert.
Total Limit Hysteresis
Set the hysteresis band for the total limit to determine how quickly the
transmitter comes out of Alert status.
Diagnostic Status Alert
Turn ON / OFF the diagnostics that will cause this Alert to activate.
ON – The Diagnostic Status Alert will activate when a transmitter detects a
diagnostic designated as ON.
OFF – The Diagnostic Status Alert will not activate when diagnostics
designated as OFF are detected.
Reverse Flow
Enable or disable the transmitter’s ability to read reverse flow.
Reverse Flow allows the transmitter to read negative flow. This may occur
when flow in the pipe is going the negative direction, or when either electrode
wires or coil wires are reversed. This also enables the totalizer to count in the
reverse direction.
Totalizer Setup
The totalizer setup menu allows for the viewing and configuration of the
totalizer parameters.
