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 12month 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 without charge.

Internal battery option is not available with ATEX and IEC 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:

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 for standard values such as pressure, temperature, and differential pressure as well as meter run flow rates. In addition to these standard alarms, the FB1100 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.

History

The FB1100 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 35 variables including flow weighted average data, totals, and gas composition. For averaging, the FB1100 supports either flow weighted or flow dependent which can be linear or formulaic.

The FB1100 can store the following:

▪	Hourly logs	62 days
▪	Daily logs	12 months
▪	Weekly logs	12 months
▪	Monthly logs	60 months

The flow computer also supports two user periodic logs, the duration or period of each is user selectable between 1 minute 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-complaint. cfx files through the FBxConnect tool as well as calibration reports which contain U.S. Bureau of Land Management specific parameters.

Housing

The FB1100 includes an explosion-proof and flame-proof enclosure made of die-cast aluminum or stainless steel that can operate in an unprotected outdoor environment. Wiring for I/O, communications, and power enters the enclosure through the four conduit fittings. The front end cap provides a viewing window for the optional LCD. The rear end cap provides access to the screw terminals. The end caps can also be fitted with wire security seals.

Hazardous Area Certifications

The FB1100 has the following Global Hazardous Area Approvals:

▪North American certification for Class I Division 1 Groups C and D (explosion proof) and Class I Division 2 Groups A, B, C and D

▪ATEX and IECEx certification for Exd Zone 1 (flame proof) and Exn Zone 2 hazardous locations

Configuration Software

Emerson’s new FBxConnect tool is a Microsoft® Windows®- based tool that enables you to easily monitor, configure, service, and calibrate the FB1100 flow computer. Designed for ease of use, FBxConnect provides at-a-glance monitoring, quick access to commonly performed tasks, and a guided configuration process to quickly get your measurement up and running.

The wizard-driven approach simplifies configuration and ensures that you only need to enter the required data once. Whether you are an experienced engineer or a new technician, you can be confident configuration is done correctly the first time.

FBxConnect runs on a Windows PC or tablet. You connect securely to the flow computer using one of its serial ports or optionally through the FBxWifi wireless connection. For more information, refer to product data sheet FBxConnect (D301789X012).

Multivariable Sensor

Enabled by superior sensor technology and engineered for optimal flow performance, the MVS on the FB1100 delivers unparalleled accuracy over a wide range of operating

conditions and industry leading stability. Pressure inputs on the sensor are used to measure differential (up to 1000” of water) and static (absolute or gauge) pressure with an operating range of up to 3600 psi and accuracies of up to 0.075%.

DP Meter

Temperature Input (RTD/PRT)

With industry-leading measurement accuracy, the temperature measurement of the FB1100 will ensure that you minimize your measurement uncertainty in all operating conditions. The input accepts two-, three-, or four-wire connections reducing any field wiring induced errors and also supports sensor curve matching utilizing the optional Callendar Van-Dusen constants to define the unique characteristics of the RTD/PRT to further improve process temperature measurement uncertainty.

The FB1100 flow computer’s superior static pressure, differential pressure (DP) and temperature measurement performance and stability ensures you meet standards and regulations so you can avoid fines, penalties, leaseholder disputes, and lost revenue. With the advanced measurement, you’re getting the most accurate flow reading to ensure you meet your company and regulatory performance requirements.

The FB1100 includes a single discrete output (DO) which provides the ability to control various discrete output field devices. The DO channel is a solid-state, normally open switch rated at 500 mA, enough to directly drive most odorizers or samplers. The DO channel can be software configured as a latched, toggled, momentary, timed duration output (TDO), or scaled pulse output.

Communications

The FB1100 has three serial communications ports with support for RS-232, RS-422, and/or RS-485 operation, and one port that supports optional FBxWifi (802.11 b/g) communications using DNP3 protocol.

▪COM1 – 4-wire serial communications. Software selectable for EIA-232 (RS-232), EIA-422 (RS-422), or EIA485 (RS-485) operation.

▪COM2 – 2-wire serial communications. Software selectable for EIA-232 (RS-232) or EIA-485 (RS-485) operation.

▪COM3 – 2-wire serial communications. Software selectable for EIA-232 (RS-232) or EIA-485 (RS-485) operation.

▪COM4 –FBxWifi (802.11 b/g) communications (optional).

The FB1100 supports DNP3, Modbus slave (ASCII and RTU), BSAP, and ROC protocols on the three serial ports and DNP3 on the FBxWifi port.

Mounting Options

The flow computer supports either direct mount to a manifold on the pipeline or indirect mounting on a two-inch pipe or pole. A mounting bracket and bolts are available for use with a traditional flange or coplanar flange.

Security

To secure your valuable process and data, the FB1100 provides multi-level role-based access, user account authentication, and password encryption.

The system administrator can set a minimum password length (up to 20 characters) that accommodates lower case, upper case, numbers, and symbols, as well as configure a user lock-out feature that locks out invalid users after a defined number of failed login attempts.
