FP90 Series

440
The FP90 Series flow transmitter
is an advanced solution that
converts the signal from many flow
sensors into a 4 to 20 mA signal
for long distance transmission.
Configuration flexibility is maximized
with two optional relays for process
control, two packaging options for
integral/pipe mount or panel
installation, and scalability for
virtually any flow range or
engineering unit. State-of-the-art
electronic design ensures long-term
reliability, signal stability, and simple
user setup and operation. The FP90
can be integrally mounted to
FP8500 Series paddlewheel
sensors utilizing a mounting kit.
F-31
The FP90 can be remotely used
with the OMEGA®FP-5100,
FP-5200, FP-5300, FP-5060,
FP-2541, FP-5600, FP-3-1500 or
FP-6000 flow sensors and an
FP90UM mounting kit. The
FP90-XP units are designed to be
panel mounted. The three front keys
control all programming and scaling
of the FP90—there are no pots to
tweak or internal adjustments to
make. Simply enter the K-factor and
the FP90 displays rate with fieldadjustable decimal point, mA output
value, total (field selectable for
resettable or non-resettable
operation) and the date of the last
reprogramming. The 8-digit
alphanumeric LCD shows every
program step in clear language,
allowing display in any engineering
units and timebase in seconds,
minutes, hours or days. A special
pushbutton sequence permits entry
into the programming, thus
providing security against
unauthorized reprogramming.
