GENERAL INFORMATION, FEATURES, SPECIFICATIONS
FEATURES
Thread-in Sensor, Field Replaceable,
6-24 Vdc pulse
18’ Sensor Cable
Standard Acrylic Top (SPX)
Removable Lens Assembly
Hex Screws
Female NPT Ports (SAE optional)
These versatile impeller flowmeters are available in 3/8", 1/2”,
3/4”, and 1" nominal pipe sizes with female NPT threads (SAE
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 economi-
cal 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-corrosive 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.
The SPT offers greater chemical resistance with a Teflon body
and cover, Teflon-coated Viton O-ring, and standard Kynar/
ceramic rotor assembly (carbide shaft optional).
The pulse output of these meters is compatible with many dif-
ferent types of controls, including a full range of Seametrics rate
displays and controls. The Seametrics FT420 provides flow rate
and total flow indication, with 4-20 mA ouput 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.
