Emerson FB2200 Flow Computer Power Security

Security

To secure your valuable process and data, the FB2200

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.

Additionally, the DNP3 protocol lends itself to an added

layer of security through Secure Authentication (SA).

SA version 5 (SAv5) is available in the FB2200 Flow

Computer as a selection in the firmware. SAv5

authenticates the devices which significantly improves

resistance to outside influence.

Integral Pressure Sensor Options

The flow computer can be supplied with one of three

sensor options to suit your metering needs:

▪ Integral Multivariable Sensor (MVS) measuring

both static pressure and differential pressure (DP)

▪ Integral inline static pressure sensor

▪ NO integral pressure sensor – external transmitters

are used

The NO integral sensor option is typically used at

locations where regulations classify the location of the

pressure measurement sensor as either C1 D1 or

ATEX/IEC Exd Zone 1. In this instance, the FB2200

without an integral sensor can be mounted in the C1

D2 / Zone 2 area and be connected via a serial port to 1

or 2 remote 4088B MVT transmitters.

If the FB2200 has an integral sensor, it can

communicate with one remote 4088B transmitter for

dual meter run applications.

Enabled by superior sensor technology and

engineered for optimal flow performance, the integral

pressure sensor on the flow computer delivers

unparalleled accuracy, over a wide range of operating

conditions, and industry leading stability to ensure you

meet standards and regulations.

Pressure sensors on the flow computer can measure

DPs of up to 1000” of water / 2500 mBar and static

pressures up to 4000 psi / 275 bar in either gauge or

absolute with accuracies up to 0.05% of reading.
