1.2 Product Overview
The FB100-Series—whether the FB103 or FB104—is a 32-bit
microprocessor-based electronic flow computer. The FB100
electronically measures, monitors, and manages gas flow for a single
meter run using orifice plate, rotary meter, or turbine meter techniques.
This economical flow computer reliably and accurately performs gas
flow calculations, temperature measurements, data archival, and remote
communications with an optional communications card installed.
Note: Any functional differences between the FB103 and FB104 are
noted in the text.
The FB100 performs minute, hourly (periodic), daily, and minimum /
maximum historical data archivals for standard history and a
configurable time interval archival for extended history. The FloBoss
103 is the perfect solution to electronically replace traditional paper
charting. The FB100 records the corrected gas flow across an orifice
plate or meter, stores the data, and has the ability to send the data to a
remote host.
The FB100 computes gas flow for both volume and energy. It provides
on-site functionality and supports remote monitoring, measurement,
data archival, communications, and control. The design of the FB100
allows you to configure specific applications, including those requiring
logic and sequencing control using a Function Sequence Table (FST).
Note: For further information on FSTs, refer to the Function Sequence
Table (FST) User Manual (part D301058X012).

1.3.1 Flow Measurement
The primary function of the FB100-Series is to measure the flow of
natural gas through an orifice or turbine or rotary meter in accordance
with the 1992 American Petroleum Institute (API) and American Gas
Association (AGA) standards.
The primary inputs used for AGA3 flow measurement function are
differential pressure, static pressure, and temperature. The differential
and static pressure inputs, which are sampled once per second, come
from the Dual-Variable Sensor. The temperature input, which is
sampled and linearized once per second, comes from an RTD probe.
The primary inputs used for AGA7 flow measurement are Pulse Input
(PI) counts, static pressure, and temperature. The Pulse Input counts are
acquired from a rotary meter (pulse interface module) or turbine meter
(PI on termination board), the static pressure (including auxiliary
pressure) inputs come from the pressure transducers, and the
temperature input is read from an RTD probe.
Flow Calculations for
Orifice Metering
The flow calculation is in accordance with ANSI/API 2530-92 (AGA
Report No. 3 1992), API Chapter 14.2 (AGA Report No. 8 1992 2nd
printing 1994), and API Chapter 21.1. The flow calculation may be
configured for either metric or English units.
Flow Timer
The differential pressure stored for each second is compared to the
configured low flow cutoff. If the differential pressure is less than or
equal to the low flow cutoff or the converted static pressure is less than
or equal to zero, flow is considered to be zero for that second.
Flow time for a recalculation period is defined to be the number of
seconds for which the differential pressure exceeded the low flow
cutoff.
Input and Extension
Calculation
Each second the FB100-Series stores the measured input for differential
pressure, static pressure, and temperature and calculates the Integral
Value (IV). IV is the square root of the absolute upstream static pressure
multiplied by the differential pressure.
The FB100-Series calculates flow time averages of the inputs and the IV
over the configured calculation period, unless there is no flow for an
entire calculation period. Linear averages of the inputs are recorded to
allow monitoring during no flow periods.
Instantaneous Rate
Calculations
The instantaneous value of the Integral Value (IV) is used with the
previous calculation period’s Integral Multiplier Value (IMV) to
compute the instantaneous flow rate.
The IMV is defined as the value resulting from the calculation of all
other factors of the flow rate equation not included in the IV. The
instantaneous flow rate is used with the volumetric heating value to
compute the instantaneous energy rate.
Flow and Energy
The averages of the differential and static pressure, temperature, and
sum of the IV are used with the flow time to compute the flow and

Accumulation
energy over the calculation period. The flow and energy are then
accumulated and stored at the top of every hour. At the configured
contract hour, the flow and energy are then stored to the Daily Historical
Log and zeroed for the start of a new day (contract hour).
Flow Calculations for
Turbine Metering
The turbine flow calculation is in accordance with 1996 AGA Report
No. 7 (1993 API Chapter 21.1). The FloBoss performs 1992 AGA8
compressibility calculations in accordance with AGA Report No. 8
1992 (API Chapter 14.2).
Once every scan period, the FB100 processes the pulse counts,
determines the number of pulse counts since the last reading, and
calculates a rate. Next, the static pressure and auxiliary pressure values
are read. Then the temperature is read and linearizing compensation is
applied to the pressure readings if necessary.
All resultant values are stored in the current value database. The values
are taken from the current value database and used to calculate the
Minute, Hour, and Daily historical values.
Once a minute and once an hour, the values are logged along with other
configured values to the Historical Database. At the configured Contract
Hour, the values are stored to the Daily Historical Log and zeroed for
the start of a new day.
1.3.2 History Points
History is saved to 2 databases: Standard and Extended History. The
number of entries/logs available to Standard and Extended History is
configurable.
The Standard history archives up to 35 points (8 are pre-configured) of
min/max, minute, hourly and daily values. The min/max values are from
today and yesterday; the minute values are from the last 60 minutes; the
hourly values are from the last 35 days; and the daily values are from
the last 35 days.
The Extended History database creates one entry for up to 15 points at a
user-specified interval (see Specifications table). All the points in the
Extended History will be logged at the same interval.
The default setting for Extended history archives 4 points of 10-minute
values (from the last 35 days). 10-minute archiving provides a
monitoring resolution similar to a chart recorder.
The first eight history points are pre-configured for flow metering
history and cannot be changed:
1. Flowing Minutes Today (Accumulate archive type).
2. Differential Pressure for AGA3 (Average) or Accumulated Raw
Pulses for AGA7 (Totalize).
3. Static or Line Pressure (Average).
4. Flowing Temperature (Average).

FloBoss 103/104 Instruction Manual
Revised August-2017 General Information 1-13
5. IMV (Integral Multiplier Value) for AGA3 (Average) or BMV
(Base Multiplier Value) for AGA7 (Average).
6. Pressure Extension for AGA3 (Average) or Today’s Total for AGA7
(Totalize).
7. Instantaneous Flow (Accumulate).
8. Instantaneous Energy (Accumulate).
History Point 2 (AGA3), History Point 3, History Point 4, and History
Point 6 (AGA3) are all pre-defined as an Average Archive Type that
employs one of the following techniques:
▪Flow dependent time-weighted linear averaging (default)
▪Flow dependent time-weighted formulaic averaging
▪Flow-weighted linear averaging
▪Flow-weighted formulaic averaging
The Averaging Technique is selected by using ROCLINK 800 software.
The selected Averaging Technique is applied to the meter inputs. Refer
to the ROCLINK 800 Configuration Software User Manual (Part
D301159X012).
Minute Historical
Log
The FB100 has a 60-minute historical log for every history point. The
Minute Historical Log stores the last 60 minutes of data from the current
minute. Each history point has Minute Historical Log entries, unless the
history point is configured for FST-controlled logging.
Hourly Historical
Log
The FB100 has a total of 35 days of hourly historical logs available for
every history point. The Hourly Historical Log is also called the
periodic database. With two exceptions (FST Minute and FST Second
logging), the system records the Hourly Log at the beginning of every
hour.
The time stamp for periodic logging consists of the month, day, hour,
and minute. The exception is for FST Second logging, in which the time
stamp consists of the day, hour, minute, and second.
Daily Historical
Log
The FB100 has a total of 35 daily historical logs for every history point.
The Daily Log is recorded at the configured contract hour every day
with a time stamp that is the same as the Hourly Log. Each history point
has daily historical log entries, unless the history point is configured for
FST-controlled logging.
Mix/Max Historical
Log
The Min / Max database displays the minimum and the maximum
values for the database points over a 24-hour period for today and
yesterday. You can view the Min / Max historical log but not save it to
disk.

FloBoss 103/104 Instruction Manual
1-14 General Information Revised August-2017
Extended History
Log
The FB100 has configurable archive times (1 minute to 60 minutes)
which, in turn, determine the number of entries.
Alarm Log
The Alarm Log contains the change in the state of any alarm signal that
has been enabled for alarms. The system Alarm Log has the capacity to
maintain and store up to 240 alarms in a “circular” log. The Alarm Log
has information fields that include time and date stamp, alarm clear or
set indicator, and either the Tag name of the point or a 14-byte detail
string in ASCII format.
In addition to providing functionality for appending new alarms to the
log, the Alarm Log allows host packages to request the index of the
most recently logged alarm entry. Alarm logging is available internally
to the system, to external host packages, and to FSTs. Alarm Logs are
not stored to the flash ROM during the Save Configuration function in
ROCLINK 800 software.
The Alarm Log operates in a circular fashion with new entries
overwriting the oldest entry when the buffer is full. The Alarm Log
provides an audit history trail of past alarms. The Alarm Log and the
Event Log are stored separately to prevent recurring alarms from
overwriting configuration audit data.
Event Log
The Event Log contains changes to any parameter within the FB100
made through the protocol. This Event Log also contains other FloBoss
events, such as power cycles, cold starts, and disk configuration
downloads. The Event Log provides an audit history trail of past
operation and changes.
The system Event Log has the capacity to maintain and store up to 240
events in a circular log. The Event Log has information fields that
includes point type, parameter number, time and date stamp, point
number if applicable, the operator identification, and either the previous,
current parameter values, and either the Tag name of the point or a 14-
byte detail string in ASCII format.
In addition to providing functionality for appending new events to the
log, the Event Log allows host packages to request the index of the most
recently logged event entry. Event logging is available internally to the
system, to external host packages, and to the FST.
Event logs are not stored to flash ROM when you perform a Save
Configuration using ROCLINK 800 software. The Event Log operates
in a circular fashion with new entries overwriting the oldest entry when
the buffer is full. The Event Log provides an audit trail history of past
operation and changes. The Event Log and Alarm Log are stored
separately to prevent recurring alarms from overwriting configuration
audit data.
The FB100 has the ability to limit the AGA calculation-related events to
only critical events. This can keep unnecessary events from being
logged and filling the event log. The events which will not be logged are
