13. Auxiliary relay (optional kit)
The Auxiliary Relay option is a valuable feature that allows the FlowVis Digital user to control external devices such as Heater
and Chemical Feeders at user-defined flow rates. For example, you may want to control the Chemical Feeder to operate only
above 20 GPM. Setting this value is discussed in Section 12.
