LMX Flow Meters Litre Meter Pelton Wheel Series


Also known as a radial turbine the highly efficient Pelton Wheel meter has some major advantages. The very large blade area compared with the flow inlet port size produces an exceptionally wide range flowmeter which can measure very low flows. The flow through the inlet of the meter is accurately directed onto the rotor which rotates at a speed in linear proportion to the flow rate.

LMX Flow Meters Litre Meter Pelton Wheel Series

A small sensing coil detects the ferrites mounted in the rotor blade tips as they pass. No drag is imposed on the rotor which assists in the measurement of extremely low flows. Sapphire bearings provide a very low friction mechanically-robust bearing with long life characteristics. Turndown can be as high as 280:1.

Each size pelton wheel flowmeter has its flow rate range controlled by jet size. For example, the LM24 has a 2.4mm diameter jet and a flow range of 0.03 to 4.3 litres per minute.

The LMX series are in line. The stainless steel units incorporate inlet and outlet pipes.
