KOSBE
(Flow Switch)

Product Discription

KOSBE Series (Sight Flow Indicator & Flow Switch) integrates a visual flow indication function for on-site confirmation of fluid flow in piping, with a flow switch function that provides dry contact (ON/OFF) output when flow reaches a set condition—such as Flow/No-Flow or minimum flow. It is ideal for various lines including cooling water, lubricating oil, and process water to detect abnormal flow conditions and supports pump dry-run prevention, cooling-water loss monitoring, and alarm/interlock integration with PLC/DCS.

✔ On-site visual confirmation + control panel alarm/interlock (contact output)
✔ Optimized for Flow/No-Flow monitoring
✔ Enhanced equipment protection: pump dry-run, heater dry-run, cooling-water loss, etc.
✔ Applicable to different piping conditions (threaded/flanged, etc.)
✔ Simple structure for easy installation and maintenance
