Limited Time and Resources?

Operate more effectively with simplified configuration and support.

Simplified configuration and support of devices make every aspect of your operation more

effective. The new family of flow computers offers a variety of features that reduce the time

required to configure devices, reduce the likelihood of configuration errors, and reduce the

amount of training required to be effective.

Concerned with Operator Safety?

Access data locally without compromising safety.

Maintaining a safe operation is your top priority, and yet technicians are typically required to

compromise hazardous area approvals to access flow computers. No longer. With FBxWifi or the

Local Interactive Display, the FB2000-Series Flow Computers can be accessed for data collection, set

point and configuration changes, easily without opening the enclosure – which makes your people,

equipment, and operation safer than ever.

Enhanced Metrology Platform Minimized measurement risk.

With an industry-leading global suite of metrology calculations –

validated by third parties – you can be confident that no matter where

you are you’ll find what you need. Add in enhanced fallback mode, global

compliance, and role-based security and you can be confident that

measurement risk has been minimized with all your calculations in the

base firmware and your audit risks are contained.

FB2100 and FB2200 Emerson’s Next Generation Flow Computer

Emerson’s new field mount flow computer family provides a new solution to flow metering and

flow computing where challenges with power, safety and measurement accuracy are addressed,

delivering a more convenient approach to remote oil and gas production sites.

The entire family of flow computers provide API, AGA and ISO compliant gas measurement for

single or dual meter runs. Extensive control alarming, reporting, and event log capabilities provide

operators with required data to ensure optimal measurement certainty and production efficiency.

Inconsistent Measurements?

Gain measurement confidence with unmatched accuracy.

Measurement uncertainty is a critical consideration of all oil

and gas producers. With the FB2000-Series Flow Computer

you can further reduce measurement uncertainty. Our

combination of best-in-class sensor stability and temperature

measurement coupled with industry leading fallback

options drive measurement performance to industry leading

levels. Our ease-of-use features make it less likely that

measurements will be misconfigured.

Communications Protocols

The FB2200 supports multiple communications

protocols, including DNP3. Modbus master and slave

(ASCII and RTU), BSAP, and ROC on the three serial

ports. In addition, the Ethernet port supports RTU

Modbus over TCP/IP protocol (master and slave),

DNP3/IP, ROC and BSAP.

FBxNet™

FBxNet is a secure, easily configurable, peer-to-peer

communication network for exchanging data between

Emerson FB3000 RTUs and FB1200 and FB2200 flow

computers over an Ethernet connection. FBxNet

supports subscriber and publisher devices, where

publishers provide data to their subscribers. The

FB3000 RTUs and FB1200 and FB2200 flow computers

can be publishers; only an FB3000 can be a subscriber.

For more information, refer to product data sheet

FBxNet (part D301905X012).

Mounting Options

The FB2200 supports direct mounting to a manifold on

the pipeline, simple wall mounting, or mounting on a

two-inch pipe with the stainless steel pipe mounting kit.

selectable for EIA-232 (RS-232), EIA-422 (RS-422), or

EIA-485 (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).

▪ COM5 – Ethernet. 10/100BASE-T twisted pair.

Supports up to seven sessions.

User Data Points – User data points are configurable

storage areas in the data base. These user data points

can store the constants / variables that are inputs to

the math blocks in addition to the calculated results of

math blocks. They can also be used to represent

interim calculation values or values of additional inputs

or outputs etc. There are eight user data instances,

each with a tag and description, 30 integers (split

between byte, short and long), 20 single floating

points, and 10 double floating points, providing

storage for up to 480 variables.

storage for up to 480 variables.

Math Blocks – The FB2200 supports up to ten math

blocks. Math blocks perform mathematical equations

using user-defined variables as inputs. Each math

block consists of up to four user-defined variables,

three mathematical calculations, and the results of

each calculation.

The result of the math block equation can be assigned

to a user data point, to drive an output point, to a

calculated value or to any other data base parameter.

Mathematical calculations also support standard math

functions (POW, EXP, LOG, SQRT, etc.), constants, and

operators.

FBxConnect checks each calculation string for the

correct syntax and uses double precision floating point

math throughout the calculation.

Action Blocks – The FB2200 supports up to 30 action

blocks. Action blocks are used in conjunction with

effect blocks to monitor a configured condition and to

perform an action (effect) when the logic is “true.” An

action block consists of a user defined Boolean logic

statement with two variables. These variables can

either be live parameter values or constants.

Multiple action blocks can be chained together to

create more complex logic. Each action block includes

multiple bypasses, which can temporarily halt the

action to be taken for maintenance and safety.

Effects – The FB2200 supports up to ten effects. Effects

cause an action to occur when the result of one or

more action blocks is active (“true”). Multiple action

blocks can cause the same effect, such as shutting a

valve or enabling an alert beacon.

You configure an effect by defining an output

parameter and the values to write to that parameter

when the effect is either active or inactive. You can also

configure an active effect to be self-clearing or to

require a manual reset.

Control

The FB2200 optionally supports control functions

including PID control, basic programming through

action blocks, effects, and math blocks.

PID Control – The FB2200 supports up to three

Proportional, Integral, and Derivative (PID) control

loops. Each PID instance supports a primary and an

override loop. Each loop has its own user-defined

input, output, and override capability.

Typically, a PID control maintains a process variable at

set point. If you configure a PID override control, the

primary loop is normally in control of the control

device but the override loop can take over control of

the process if required. A typical example would be

primary flow control with a pressure override.

Mounting Options

The FB2200 supports direct mounting to a manifold on

the pipeline, simple wall mounting, or mounting on a

two-inch pipe with the stainless steel pipe mounting kit.

Expansion I/O

In addition to the base I/O provided, the FB2200 I/O

capability can be increased by adding two options. The

expansion below provides 2500 Vdc isolation from the CPU.

▪ 8-channel isolated expansion board, providing 4

channels that are individually software-selectable

as either analog inputs or analog outputs and 4

channels that are individually selectable as discrete

inputs, discrete outputs, or pulse inputs.

▪ 6-channel isolated expansion board, providing 2

channels that are individually software-selectable

as either analog inputs or analog outputs and 4

channels that are individually selectable as discrete

inputs, discrete outputs, or pulse inputs.

Note: The 8-channel expansion board option must be

added first. The 6-channel expansion board can

only be used in units that already have the 8

channel board included.

▪ Two optional relays allow for additional loads up to

30 Vdc at 6A. 24 Vdc is required to energize the

relays or an expansion I/O option must be selected,

which enables 24 Vdc loop.

Note: This option is available only with Class 1 Div 2 approval.
