This category contains sensors with an electrical contact output at a specific air flow rate. Applications include low air flow condition duct alarm, fan monitoring, damper feedback, air handlers, and air flow proving in HVAC systems.
What is a Flow Switch Used For? As previously stated, flow switches are used to monitor and control the flow rate of fluid within an industrial process system. Automated industrial systems that process fluid media rely heavily on flow switches to ensure safe and optimal flow rates.
