Pelton Wheel Flowmeters

The Litre Meter Pelton Wheel flowmeters employ a single size straight bladed rotor manufactured in chemically resistant PFA with bearings of sapphire. The rotor runs in hemispherical sapphire bearing cups forming two 'floating' low friction precision bearings. Ferrites sealed in the PFA rotor are sensed by a pick-up coil in the Litre Meter sensor. The flow path for the LM series meters is shown where all of the flow travels with the Pelton Wheel and exits from the flowmeter. The meter provides a square wave pulse output. LM Series meters are specifically designed for low flows and have a wide turndown ratio of up to 280:1.

For the MM Series an identical Pelton Wheel ring assembly is located in a by-pass chamber. The rotor movement is directly proportional to total flow through the flowmeter. This gives a wide rangeability, typically 50:1 for the MM orifice/by-pass meter.
