Weber Sensors 4120.13A BSP Flow-Captor Metering Flow Switch with Analog LED Display with 2 m Silicone Cable, 24 VDC
- Part #:4120.13A BSP
- Model #:Flow-Captor
- Condition:Brand New

The flow-captor is ideally suited for use in automation processes or other industrial applications where liquid media must be monitored. The sensor works according to the calorimetric measuring principle, fully electronic and without mechanically moving parts. The flow-captor detects the flow velocity of the medium and converts it into an electrical signal.
