This multi-range radial flow turbine meter uses a low inertia turbine supported on robust sapphire bearings in a chemically resistant housing. Nine flow ranges (0.05 to 160 litres per minute), a choice of plug in fittings and individual traceable calibration make this meter one of the most flexible available. It uses Hall Effect sensing so that opaque fluids may still be metered.

Redux flow cells have had nowhere near the R+D effort compared to Lithium ion. They certainly have the potential (pun not intended) for longer...
