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.
