2.5.1 Units of measure
If a unit of measure is edited and the Apply button is selected, the unit of measure will be
changed in the device memory and on screen, but the value may take up to 30 seconds to
be updated on the AMS Device Manager screen.

• Verify the Device Tag information. The tag information is used to identify specific
transmitters on the 4–20 mA loop. This tag information may be edited.
• Under the Flow Rate heading (fully compensated mass and energy flow feature board
only), the type of flow calculation (mass or volumetric) is displayed by the indicators on
the right side of the box. The Flow Calculation Type may be edited by selecting the
Configure Flow Calculation Type button. The Damping and Units of the Flow Rate may
also be edited under this heading.
Note
The flow calculation within the device uses undamped process variables. Flow rate
damping is set independently of measured process variables.
• Under the Energy Rate heading (fully compensated mass and energy flow feature
board only), the Units and Damping for the Energy Rate may be edited.
Note
Energy rate calculations are only available for steam and natural gas. The energy rate
calculation within the device uses undamped process variables. Energy rate damping is set
independently of flow rate damping or measured process variables.
• Under the Differential Pressure heading, the Units and Damping for the Differential
Pressure may be edited.
• Under the Static Pressure heading, the Units for both absolute and gage pressure and
static pressure Damping may be edited.
Note
Both absolute and gage pressure are available as variables. The type of transmitter ordered
will determine which variable is measured and which is calculated based on the user
