For maintaining critical product purity or for safe transport of 
highly corrosive acids, you can depend on OMEGA’s all-PVDF 
flow monitoring systems. Known for its superior heat-resistance 
and thermal stability, PVDF is quickly becoming the preferred piping 
material in many ultra-pure water and acid transport applications. 
Using no dyes or stabilizers, OMEGA offers the only “pure” PVDF 
flow-monitoring system. Available for installation in pipe sizes 
ranging from 
FOR ULTRA-PURE CONFIDENCE
Combine OMEGA’s PVDF flow monitoring system with your 
existing PVDF pipe—including SYGEF, PVDF, and SUPER 
PROLINE. This all-PVDF system completely eliminates the 
possibility of contaminated fluid product, making it perfect for 
measuring D.I. water in cosmetic, food, and pharmaceutical 
production. In addition, processes utilizing D.I. water in the 
semiconductor industry can be monitored with total confidence. 
FOR SAFE ACID TRANSPORT
When pumping hydrofluoric acid to wafer etching tanks...processing 
sulfuric acid through water treatment skid for regeneration...or 
transporting harsh solvents, OMEGA’s PVDF flow monitoring 
systems provide rugged, corrosion-resistant construction.
EASY INSTALLATION
PVDF Sensor installation Tee fittings allow direct compatibility with 
SYGEF piping, joined by the fusion using special 
electro heating elements. The socket fusion 
process combines simple handling with high 
operational safety and reliability. When 
used in PVDF or SUPER PROLINE piping 
systems, a flange connection is 
recommended.

DURABLE 
POLYPROPYLENE 
(See FP-5300 Series, 
omega.com/fp5300)
OMEGA also offers sensors and 
fittings constructed of durable 
polypropylene. This lightweight 
material is strong enough for a wide 
range of fluid applications, and 
polypro is rugged for longer wear, 
which saves you money by reducing 
replacement and servicing costs.

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.

WARNING: THE ABOVE PRESSURE/TEMPERATURE CURVES ARE SPECIFICALLY FOR THE FP-5100. 
FP-5300, AND FP-8500 SENSORS. DURING SYSTEM DESIGN, THE SPECIFICATIONS OF ALL 
COMPONENTS MUST BE CONSIDERED. IN A METAL PIPING SYSTEM, A PLASTIC SENSOR WILL 
REDUCE THE SYSTEM SPEC. ON THE OTHER HAND, IF USING A PVDF SENSOR IN A PVC PIPING 
SYSTEM, THE FITTING WILL REDUCE THE SYSTEM SPEC.

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.
