The Litre Meter pelton wheel flowmeter was first patented in 1975 and has an established reputation for function and reliability. Flows from 0.004 l/min can be metered up to 28 l/min using our LM series range. Large flowmeters are provided utilising the orifice/bypass principle where a wide flow range is given and the ability to measure low flows is retained. Pelton Wheel flowmeters are suitable for low viscosity clean fluids with variants in all- PFA Teflon for maximum chemical resistance and high pressure types to 2000 bar at the other end of the spectrum.
