Configure Gas Standard Volume Flow Unit

ProLink III
Field Communicator Configure > Manual Setup > Measurements > GSV > GSV Flow Unit
Overview
Gas Standard Volume Flow Unit specifies the unit of measure that will be displayed for the
gas standard volume flow. The measurement unit used for the gas volume total and the
gas volume inventory is derived from this unit.
Prerequisites
Before you configure Gas Standard Volume Flow Unit, be sure that Volume Flow Type is set
to Gas Standard Volume.
For polling, the first transmitter (master) requests density from a second transmitter
(slave) via HART communications. Special units for GSV are allowed on the master side,
but the device being polled (slave) cannot have special units set for density, otherwise the
master will reject the base density and report an A115: No External Input or Polled Data
Alert.
Procedure
Set Gas Standard Volume Flow Unit to the unit you want to use.
Configuration and Use Manual
Option Description
Poll as Secondary Other HART masters will be on the network.
Set External Device Tag n to the HART tag of the device being polled.
The n is the value you selected in the Polling Slot field.
• The device being polled (slave) cannot have special units set for density.
Otherwise, the master will reject the base density and report the following alarm:
A115: No External Input or Polled Data Alert
• On the slave side, setup the HART Primary Variable for Base Density. The master
will reject anything other than Base Density for the HART Primary Variable and
trigger an A115 alarm.
• The density units on the transmitter and the polled device can be different as
long as they can be classified as density units; for example, kg/m
The transmitter converts the polled units into compatible specified units.
For wiring and setup instructions for a polled device, refer to the Micro Motion Gas
Density Meters (GDM) Installation manual or the Micro Motion Specific Gravity Meters
(SGM) Installation manual.
