Puriflow offer a range of top quality electronic Water Softeners suitable for both domestic and commercial situations which require the use of a power supply and have the extra advantage of being fully programmable. These are available as either metered or time clock controlled Clack valves.
1) Metered Based Water Softeners – This type measures the amount of water consumption and only regenerates when necessary. This saves both salt and water used during the softener regeneration process. This is when the salt solution is mixed with water and backwashed through the tank to recharge the softening resin inside the tank, a bit like recharging a battery. While costing slightly more than timer (clock) based softeners, metered units will lead to savings in salt and water over time.
2) Time Clock Based Water Softeners - Time clock water softeners regenerate on a calendar basis when you set it to do so rather than automatically.
In conclusion, the only real difference is that metered systems are more cost effective, in the long run by saving you salt and water. The reason we offer both is because if your water usage is very regular and predictable, timed systems are absolutely perfect for you and more cost effective.
