Emerson FB1100 Explosion-Proof Flow Computer B222G62E12Q0 The FB1100 is a cost-effective, low-power explosion-proof flow computer that measures and monitors gas flow for a single differential pressure meter run. As well as bringing a new level of measurement confidence, the FB1100 can run independently without external power for up to one year, making it an ideal replacement for chart recorders.
FB1100 Flow Computer
The FB1100 is a cost-effective, low-power explosion-proof flow computer that measures and monitors gas flow for a single differential pressure meter run. As well as bringing a new level of measurement confidence, the FB1100 can run independently without external power for up to one year, making it an ideal replacement for chart recorders.
The FB1100 is part of Emerson’s new field-mount flow computer family that delivers a convenient approach to remote oil and gas sites by addressing challenges to power, safety, measurement reliability, and accuracy.
Designed for simple configuration and ease of use, the cost-effective FB1100 flow computer is focused on metering applications where control is not required.
The FB1100 provides a full audit trail, including enhanced history, alarm, and event logs, as well as a discrete output that can be used to drive an odorizer.
The FB1100 includes power options for the most remote sites and has flexible communication capabilities, including FBxWifi™, for both remote and networked sites.
The new flow computers also come with the latest  Rosemount™ multivariable measurement sensor
technology, providing high-accuracy differential pressure and static pressure measurement with long

term stability to help improve measurement confidence and production efficiency.

Features  
The FB1100 flow computer includes the following key features:
▪ Increased measurement confidence, reduced measurement uncertainty  
▪ Measurement and I/O capability focused on metering applications  
▪ Industry-leading differential and static pressure measurement, including 0.05% of reading accuracy  and 5-year stability  
▪ Simplified configuration and set-up with the FBxConnectTM configuration software tool  
▪ Cost-effective alternative to chart recorders  
▪ Flexible design with power and communication options to meet site needs  
▪ Standard firmware supports global calculations for DP metering including orifice, cone, Venturi, nozzle,  and conditioning orifice
▪ Standard firmware supports Properties Calculations for Natural Gas and Pure Gas
▪ Simple selection of engineering units to suit local requirements  
▪ Global Hazardous Area Approvals – Class 1 Div 1 & 2, ATEX & IEC Ex d & Ex ec
▪ FBxWifi allows secure local wireless access from a safe area
▪ Ease of integration with support for Modbus, ROC, BSAP, and DNP3 protocols  
▪ Enhanced security helps prevent unauthorized access  
▪ Enhanced alarming and historical data storage, improved audit trail  
▪ Superior performance gives better control of your operations and maximizes profits  
▪ API 21.1-compliant aluminum housing
▪ High-accuracy temperature measurement, including curve matching via the Callendar-Van Dusen equation  
▪ Reduced need to recalibrate, resulting in less time spent on site  
FBxWifi™
The optional FBxWifi communications enables you to connect your laptop or tablet to the flow computer through a secure wireless connection. Once connected wirelessly, you can use FBxConnect configuration software to view process values, edit configuration parameters, and collect logs stored in the flow computer – all from within the safe area.
Power Options
The FB1100 has the following power options:
▪ External DC supply  
▪ External DC supply with internal battery back-up
▪ Solar panel charging internal battery; FB1100 has internal solar regulator  
▪ Autonomous mode with internal battery powering the FB1100 for 12 months
In "autonomous mode," the FB1100 runs from a single battery for up to 12 months without recharging. The 12-month battery life is based on the FB1100 running in low power mode on a typical remote application with a local collection of history and the use of the optional display for up to 30 minutes per month. This option is an ideal replacement for chart recorders, significantly reducing measurement uncertainty and providing a complete electronic audit trail. The 12-month battery life is achieved under an ambient temperature of 25˚C/77˚F; refer to the table on page 10.
The solar-powered option provides up to 25 days of autonomous operation if configured to operate under
Low Power Mode. Refer to the Power Modes section of the data sheet for more details.
Note: The internal battery option is not available with ATEX and IECEx approvals.
Firmware
The base firmware in the FB1100 flow computer measures static pressure, differential pressure, and temperature for a single meter run. The flow computer performs gas flow calculations based on those inputs in either U.S., metric, or other user-selectable units based on the calculation type.  
The firmware supports the following flow calculations:
▪ AGA 3 1992/2013 (volume, mass/density, and mass/relative density)  
▪ ISO 5167 1991/1998/2003 (orifice, Venturi, and nozzle)  
▪ Rosemount® 405C Compact Orifice and 1595 Conditioning Orifice Plate  
▪ McCrometer V-Cone® and Wafer Cone®  
▪ NUFLO™ Cone  
▪ AGA 9(Multipath Ultrasonic)  
The firmware supports the following property calculations:
▪ AGA 8 1994 (Detailed, Gross 1 and Gross 2)  
▪ AGA 8 2017 Part 1 and Part 2 (GERG 2008)  
Note:  AGA 8 Part 2 / GERG 2008 provides support for the following pure gases (100%) as well as any mixtures (0% to 100%): Nitrogen, Carbon Dioxide, Hydrogen, Oxygen, Carbon Monoxide, Water Vapor, Hydrogen Sulfide, Helium, and Argon.
▪ Speed of Sound calculated via AGA 10 and AGA 8 2017 Part 2
▪ NX-19 1962, MOD, VDI/VDE 2040, Miller  
▪ ISO 12213 2006 (parts 2 and 3)  
▪ SGERG 1991 (Std., Alt 1, Alt 2, and Alt 3)  
▪ GPA 2172 2009 (including saturated vapor calculation)  
▪ ISO 6976 1995 (superior and inferior, incorporating Technical Corrigendum 2 [1997] and 3 [1999])
▪ AGA 5 2009
Regarding gas composition, the flow computer can:
▪ Receive updated gas composition from SCADA  
▪ Receive manual updates for gas composition through FBxConnect; or  
▪ Use a fixed gas composition
The firmware includes the following flow rates and totals:
▪ Uncorrected volume  
▪ Corrected (standard) volume  
▪ Mass  
▪ Energy  
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 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
