These versatile impeller flowmeters are availalble in 3/8”, 1/2”, 3/4”, and 1” nominal pipe sizes with female NPT threads. They employ jewel bearings to allow for very low minimum flow rates and superior life.
The SPX, with a body of polypropylene, is an economical choice for metering water or low corrosion fluids. The lens cover is available in a
choice of materials: acrylic for visual flow indication of low-corrosion fluids; polypropylene when more corrosion resistance is needed. The
standard rotor assembly is Kynar® with tungsten carbide shaft. The O-ring is EPDM.
The SPT offers greater chemical resistance with a Teflon® body and cover, Teflon®-coated Viton® O-ring, and standard Kynar®/ceramic rotor assembly.
The pulse output of these meters is compatible with many different types of controls, including a full range of Seametrics rate displays and
controls. The Seametrics FT430 and FT440 provide flow rate and total flow indication. The FT440 also includes 4-20 mA output capability. The FT450 is a battery-operated rate & total display.
