Flow Switch

 is used to indicate that the flow rate (measured by the configured flow variable)

has moved past the configured setpoint, in either direction. The flow switch is
implemented with a user-configurable hysteresis.

1.

Set Discrete Output Source to Flow Switch, if you have not already done so.

2.

Set Flow Switch Variable to the flow variable that you want to use to control the flow
switch.
