Keyence FD-R125 Flow Sensor, Sensor 100A/125A Type, Clamp-on Meter
Keyence’s FD-R125 is a flow sensor component. Keyence catalogs the FD-R125 as a main unit. Flow sensing confirms that coolant, water, or air is actually moving, which pressure alone cannot verify. Typical duty covers protecting spindles, welders, and induction equipment from loss of cooling. Confirm the flow range, pipe size, fluid type, and output configuration before ordering.
