Description
Streamline your flow measurement operation with the FPL300 Series flow sensor. Using this compact flow sensor, a matched sensor installation fitting, an trodeks® flow meter or controller, and ordinary hand tools, 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 FPL300. Should a sensor, rotor, or O-ring need to be replaced, it takes only seconds. Reduce your system downtime substantially with a stand- FPL300sensor, or simply add a Wet Tap Assembly and eliminate downtime completely. Combined with the FPL300 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 FPL300in pipe sizes ranging from 1/2 inch to 36 inches without a lot of additional cost, because the price of the FPL300 increases only slightly for larger pipe sizes.

Available in a choice of chemically resistant, non-contaminating housing materials, the FPL300stands 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 FPL300 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 FPL300-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.
