A third kind of control uses a mechanical water meter to measure water utilization and provoke recharging. The advantage of this system is that no electrical components are required and the mineral tank is only recharged when crucial. When it's equipped with two mineral tanks, softened water is at all times out there, even when the unit is recharging.
