6.7.1 Effects of Special mode
In Special mode:
• Not all process variables are updated. The process variables listed below are always updated:
- Mass flow
-Volume flow
- Density
- Temperature
-Drive gain
- LPO amplitude
- RPO amplitude
- Status (contains Event 1 and Event 2)
- Raw tube frequency
- Mass total
- Volume total
-Board temperature
- Core input voltage
- Mass inventory
- Volume inventory
All other process variables are not polled at all. The omitted process variables will remain at
the values they held before
Special mode was implemented.
• Calibration data is not refreshed.
Micro Motion recommends the following:
• If
Special mode is required, ensure that all required data is being updated.
• Do not perform any calibrations while in
Special mode.
6.8 Configuring the flow direction parameter
Note: If the mA output is configured for valve control, this parameter has no effect.
The flow direction parameter controls how the transmitter reports flow rate and how flow is added to
or subtracted from the totalizers, under conditions of forward flow, reverse flow, or zero flow.
• Forward (positive) flow moves in the direction of the arrow on the sensor.
• Reverse (negative) flow moves in the direction opposite of the arrow on the sensor.
Options for flow direction include:
•Forward
•Reverse
• Absolute Value
• Bidirectional
• Negate Forward
• Negate Bidirectional
