SPX Series Low-Flow Paddle Wheel Flow Sensors

SPX Series Low Flow Sensors

These versatile impeller flowmeters are availalble 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 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.

The pulse output of the SPX meter is compatible with many different types of controls, including a range of AquaMetrix displays and controls. For rate and total display, the Shark-120/240 controller or SharkTX(P) transmitter (loop powered) models are compatible with the SPX series sensors. They can be mounted in either surface, pipe or panel configurations.
