The flow computer also supports two user periodic

logs, the duration or period of each is user selectable

between 1 second and 200 hours. The first user

periodic logs include 10 parameters over 4.000 periods

and the second contains 20 parameters over 500 periods.

The flow computer with FBxConnect provides pre

formatted EFM reports for hours and days. The format

of the reports can be .csv, .pdf, or secure .pdf.

In addition to the above reports, the flow computers

can produce FLOWCAL-compliant .cfx files through the

FBxConnect tool as well as calibration reports which

contain U.S. Bureau of Land Management specific parameters.

▪ Hourly logs

▪ Daily logs

▪ Weekly logs

▪ Monthly logs

62 days or 1500 records

12 months or 365 records

12 months or 52 records

60 months or 60 records

Note: This is only the initial default history. With the

flexible history design, the number of variables

and the time duration for different periodic

logs can be adjusted to meet the application requirement.

The FB2200 features expanded and flexible history

capability to ensure measurement confidence and

meet the increasing demands for secure data.

The flow computer has four standard periodic logs

available providing hourly, daily, weekly, and monthly

history. These logs can contain up to 110 variables

including flow weighted average data, totals, and gas

composition. For averaging, the FB2200 supports

either flow weighted or flow dependent which can be

linear or formulaic.

For gas meter averages, you can choose between flow

dependent linear per API Chapter 21.1 (2013) or flow

dependent formulaic, flow-weighted linear, or flow

weighted formulaic averages per API Chapter 21.1

(1993). Liquid meter averages are flow-weighted

averages per API Chapter 21.2 (2000).

The default history in the FB2200 can store the

following standard periodic logs for 60 variables. With

the flexible history design, the number of variables and

the time duration for different periodic logs can be

adjusted to meet the application requirement.

Automated Checksum Verification (ACV)

As an extended auditing feature, the flow computer

provides an option to perform online integrity checks

by generating firmware and configuration checksums.

The checksum is a 32-bit CRC number which is

routinely calculated and compared against the last

verified checksum. If a newly calculated checksum

does not match with the last verified checksum, the

system generates a checksum error and the flow

computer goes into an unverified state.

The flow computer supports extensive alarming

capability to enhance operational efficiency and

improve the audit trail. Alarms are pre-allocated to

meter runs and stations for standard values such as

pressure, temperature, differential pressure, or

frequency as well as meter run and station flow rates.

In addition to these standard alarms, the FB2200

provides a number of user alarms that you can assign

to other database parameters simply by “filling in the

blanks” in user alarm templates in the FBxConnect

configuration tool. Storage is provided for the most

recent 1000 alarms in the alarm log.

Alarms and Events

The flow computer supports extensive alarming

capability to enhance operational efficiency and

improve the audit trail. Alarms are pre-allocated to

meter runs and stations for standard values such as

pressure, temperature, differential pressure, or

frequency as well as meter run and station flow rates.

In addition to these standard alarms, the FB2200

provides a number of user alarms that you can assign

to other database parameters simply by “filling in the

blanks” in user alarm templates in the FBxConnect

configuration tool. Storage is provided for the most

recent 1000 alarms in the alarm log.

The event log stores the significant events during

operation and can be configured to either store all

events in a single log of 2000 events or the user can

select to store the metrology/legal events in a separate

log from the operational events. With the latter option

the event log capacity is 1000 metrology events and

1000 operation events.

variable’s value is questionable. The fallback options

can be one of the following:

▪ Use last good value

▪ Use a fixed fallback value
