The model FSM-BSV flow switch is designed for flow indication and monitoring of liquids in cooling circuits and systems of welding machinery, laser and pipeline systems, dosing systems, pumps, compressors, hydraulic systems, high-pressure plants and many more.
Based on the piston working principle, a float (piston), with its integrated magnet, is moved by the medium in the direction of the flow within a cylindrical slotted nozzle or measuring tube. When the switch contact position is reached, the float stops.
When the flow rate increases, the piston moves further, at most until it reaches the end stop position, preventing the float from being driven beyond the switching range.
The flow switch enables a microswitch contact to be mounted outside of the flow circuit. The switch contact is cast into a continuously adjustable switch case and thus is protected from external influences.
The model FSM-BSV flow switch is a compact flow meter used for operational controls that prevent system failures in the absence of liquid supply.
