Low Cost Paddlewheel Flow Meter

Streamline your flow measurement operation with the FP-5100 Series flow sensor. Using this compact flow sensor, a matched sensor installation fitting, an OMEGA™ flow meter or controller, and ordinary handtools, you can assemble a complete flow monitoring or controlling system in minutes. Accurate to ±0.2 fps, with repeatability at ±0.1 fps, this insertion sensor operates on a simple electromechanical principle, proven in thousands of liquid flow applications worldwide. It all adds up to precision, dependability, and convenience– basic advantages that are quickly surpassing its in-line competition.

Convert your maintenance hours into minutes with the FP-5300. Should a sensor, rotor, or O-ring need to be replaced, it takes only seconds. Reduce your system downtime substantially with a stand-alone FP-5300 sensor, or simply add a Wet Tap Assembly and eliminate downtime completely. Combined with the FP-5300 during initial installation, the Wet Tap allows sensor removal without system shut-down. Optional local or remote capability lets you place your meter up to 200 feet away without signal amplification, and you can install the FP-5300 in pipe sizes ranging from 1/2 inch to 36 inches without a lot of additional cost, because the price of the FP-5300 increases only slightly for larger pipe sizes.

Available in a choice of chemically resistant, non-contaminating housing materials, the FP-5300 stands up to the harshest environments. The glass-filled polypropylene housing version is lightweight but strong, which makes it ideal for handling a wide range of liquids, including corrosive fluids in chemical processing. For processes involving acids and solvents, the PVDF (polyvinylidene fluoride) housing version is a tough fluorocarbon that is highly resistant to more severe fluids.

The sensor works on a simple but precise electromechanical principle based on measuring the rate and volume of flow in your pipe. Four permanent magnets, imbedded in the rotor blades, spin past a coil in the sensor body. As the fluid flow causes the rotor to move, a sine wave signal is produced, directly proportional to the flowrate. The patented “open cell” feature of the rotor ensures a linear, repeatable output, up to 20 fps, with accuracy of ±0.2 fps. The result is minimal head loss and no cavitation.

Designed to allow optional conduit installation, the FP-5300 easily lets you comply with local codes requiring conduit protection. For instance, pry off the plug on top of the sensor: underneath, you’ll find a 1/2 FNPT thread. Using an optional conduit adaptor fitting kit, you can connect your conduit FPM-5000-SCAK conduit adaptor kit), and an optional instrument back-cover kit will provide everything you need for quick conduit connection to a meter or controller. Additionally, you can adapt to both rigid and flexible liquid-tight conduits, protecting your system hookup from harsh elements and mechanical damage.
