The meter of a water softener can be likened to the engine of a car. The better the meter, the better the softener can perform. The Minimax M2 is unique in its design, and is fitted with two displacement meters. With pinpoint accuracy, they easily measure from a dripping tap all the way up to the highest flow rates of a domestic plumbing system. Other softeners are fitted with paddle wheel meters, which means that trickle flow, or creeping hard water, is an inconvenient problem home owners often have to live with.
