580 Series Excess Flow Switch

Excess flow switch for use with CONCOA 585 Series emergency shut-off controller
5804001 shown

The 580 Series Excess Flow Switch is designed to monitor and detect increasing flow rates of gases in critical processes. Unlike mechanical excess flow shut-off valves, shut-off initialized by an excess flow switch can easily be reset with a controller, such as the 585 Series emergency shut-off controller, without significant application disruption. When connected to the 585 Series ESO controller, excess flow switches monitor the rate of gas flow. If the flow reaches the pre-set flow rate, the flow switch triggers an action, such as "initiate alarm" or "initiate alarm and shutdown." Excess flow switches are tested and programmed at the factory but can be re-calibrated to the desired flow settings. CONCOA 580 Series excess flow switches ensure immediate shutdown of any gas line in the event of a pipeline break or excess flow condition.
