ACCURACY THAT PAYS OFF
In the FP-5200 sensor housing, a magnet is surrounded
by a coil, creating a magnetic field. As the liquid flow
causes the rotor to spin, each blade passing this coil
concentrates the lines of magnetic force, producing a
repeatable AC sine wave output. The FP-5200 also
features OMEGA’s patented “open-cell” rotor, for
increased linearity at ±1% over the full dynamic range
of 1.6 to 20 fps, with negligible head loss.
COMPATIBLE,
VERSATILE INTERFACING
The FP-5200 is completely compatible with FPM Series
powered flow indicators, controllers, and totalizers,
to give increased flexibility in system design. It also
interfaces easily with digital computers and with a
variety of other external equipment.
FP-5200 FLOW SENSOR
When you’re looking for the added strength of an
all-metal flow sensor, make it the FP-5200. It permits
the high degree of accuracy and reliability you demand,
without added cost. Compare it to traditional metal
flowmeters, where the price increases dramatically
with pipe size. In contrast, you can install the FP-5200
insertion flow sensor in pipe sizes ranging from 1⁄2 to
12" without a lot of additional cost, because the sensor
price increases only slightly for larger pipe sizes.
Furthermore, it’s accurate to ±1% of full scale.
Installation is easy. Use the FP-5200 locally, or in a
remote area up to 100 feet from the meter or controller
without signal amplification. It needs no external power
or battery. Just one operator, simple tools, an FP-5200
Flow Sensor, a few minutes . . . and you’re on-line.
Additionally, the all-stainless-steel flow sensor
accurately measures a wide variety of fluids,
even under high pressure and temperature
conditions [pressures up to 1500 psi, temperatures
up to150°C (300°F)].

METAL HOT-TAP FLOW SENSOR
The metal hot-tap sensor allows the user easy
sensor installation and removal without shutting down
the process stream. Compatible with Mueller drill
assemblies, this new hot-tap sensor can be quickly
installed into pipe sizes from 11⁄2 to 24". This hot-tap
assembly is compatible with any 11⁄2 NPT female pipe
fitting such as weldolets and saddles. Installation

INSTALLATION
SUGGESTIONS
FOR
PADDLEWHEEL
SENSORS
For maximum
linearity and
accuracy, the
sensor should
be located in a
straight run of
pipe upstream and
downstream of
the sensor. Major
obstructions
such as pumps
or throttle
valves
require longer
straight runs.

PRESSURE/TEMPERATURE CHARTS
For FP-5100, FP-5200, FP-5300 and FP-8500 Series
Sensors and Associated Fittings
NOTE: All pressure/temperature ratings listed are for water under non-shock conditions with no pressure cycling.
Various chemicals and cycling pressures up and down can weaken plastics. Fittings must be installed so that the
fitting does not carry the weight of the piping and does not suffer from thermal expansion stresses. Water hammer,
fluid surges, and cavitation must always be avoided. If the end user elects to thread the plastic fittings with socket
ends, the pressure rating will be substantially decreased.

These ratings are for PVC and PVDF fittings. For all metal
fittings 10” and larger, a PVC insert is used; for 8” and below, a
PVDF insert is used. Use the appropriate curve to determine the
maximum pressure rating of these fittings.
