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.

The firmware includes the following flow rates and

totals for gas DP and gas linear meters:

▪ Uncorrected volume

▪ Corrected (standard) volume

▪ Mass

▪ Energy

▪ Integral Value (DP meter) or Pulse Totals (linear meter)

In addition to the normal totals, the firmware also

supports the following fault totals which can be

enabled for a gas meter. The conditions to trigger the

fault totals are user configurable:

▪ Uncorrected volume fault totals

▪ Corrected volume fault totals

▪ Mass fault totals

▪ Energy fault totals

The firmware includes the following flow rates and

totals for API 12.2 and API 20.1 (low water):

▪ Indicated Volume / Mass

Note: The firmware can accept a water cut from an

on-line analyzer or from an off-line analyzer

corrected to metering conditions.

The firmware accepts gas density, base density, and

specific gravity from any of the following sources:

▪ Up to 2 gas chromatographs (GC)

▪ Fixed value

▪ Periodic download from SCADA

▪ An external signal, such as analog input

▪ Calculated based on gas composition

▪ For liquid meters, the flow meter signal can be

provided by a pulse input, an analog flowrate, or a

direct accumulation from the meter electronics.

The firmware supports a fallback mode when a process

variable’s value is questionable. The fallback options

can be one of the following:

▪ Use last good value

▪ Use a fixed fallback value

mixtures (0% to 100%): Nitrogen, Carbon

Dioxide, Hydrogen, Oxygen, Carbon

Monoxide, Water Vapor, Hydrogen Sulfide,
