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.
The Auxiliary Relay option kit installs into the rear of the FlowVis Digital Display enclosure and comprises the following items:
