Single Jet Low Flow Meter, Woltman Flow Meter
These versatile impeller flowmeters are available 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 a 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. For metering pump pacing or interfacing with low-speed counters, the PD10 pulse divider is recommended. The AO55 may be used for blind 4-20 mA transmission
