Meter Run Tags
Meter Run tags are created automatically when you configure a Flow Controller. You will seldom need to create or configure these tags yourself. The information in this topic is provided for reference .
The Meter Run tags are Oil & Gas Solutions tags that provide three distinct functions:
- Provide a container to hold hourly logs, daily logs, and process values, all of which are monitored using automatically-generated child tags.
- Provide a user interface to change commonly adjusted configuration settings for the flow meter run. (This is done using a widget, not by configuring the Meter Run tag.)
- Provide the tools to accept and store the meter run configuration values from the field I/O device.
The ID tab of every tag includes the same common elements: Name, Area, Description, and Help ID.
Name:
Configured automatically. This field contains a start tag expression that ensures only those Meter Runs configured in the parent tag will start.
Area
Inherited from the parent tag.
Description
Configured in the parent tag.
Help Search Key
Used only by those who have created their own CHM-format context sensitive help files to accompany their application. Refer to Custom Help Files
I/O Device
Automatically selected, based on the driver configured in the parent Flow Control tag.
Run Number

Config Scan Trigger
A code representing the Read Configuration Data property, set in the parent tag. For example, "M12" means "Monthly on the 12th". "W1" means "Weekly on the first day of the week". Times are set relative to UTC.
Config Read Timeout
The number of seconds to wait failing to read the configuration data. Defaults to 10 seconds.
