| If you want to dose at a fixed percentage to the water flow volume a layout such as below could be used. The generator produces into a tank which contains a level sensor. The level sensor can be set to a minimum and maximum which will control the start stop function of the generator. The size of buffer tank will be related to the flow of the system. A dosing pump is connected to a flow sensor and |
|
matches its speed to suit the flow rate. The advantage of the buffer tank is that if the flow rate demand for dosing is variable and at times exceeds the maximum output of the machine the shortfall is made up by the buffer tank. In this layout the flow sensor could equally well be substituted with an ORP sensor if the critical parameter was REDOX potential. |
