These versatile impeller flowmeters are availalble in 3/8”, 1/2”, 3/4”, and 1” nominal pipe sizes with female NPT threads (SAE or BSP optional). They employ jewel bearings to allow for very low minimum flow rates and superior life.
With a body material of polypropylene, the SPX 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 (ceramic shaft optional). The O-ring is EPDM (Viton or Teflon-coated Viton optional).
The pulse output of this meter 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 and total display.
