These versatile impeller fowmeters 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 fow rates and superior life. With a body material of polypropylene, the SPX is an economical choice for metering water or low corrosion fuids. The lens cover is available in a choice of materials: acrylic for visual fow indication of low-corrosion fuids; 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 Tefon body and cover, Tefon-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 FT420 provides fow rate and total fow indication, with 4-20 mA output capability. The FT415 is a battery-operated rate & total display. For metering pump pacing or interfacing with lowspeed counters, the PD10 pulse divider is recommended. The AO55 may be used for blind 4-20mA transmission.
