Seametrics SPX Low Flow Meter

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.

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 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.
