Important
This table assumes that Discrete Output Polarity is set to Active High. If Discrete Output Polarity is set to Active
Low, reverse the voltage values.
Important
If you assign flow switch to the discrete output, you must also configure Flow Switch Variable, Flow
Switch Setpoint, and Hysteresis.

Overview
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.
