- Optical flow alarm sensor for bistable and monostable use
- Bistable: sensor detects if sufficient or low flow is present
- Monostable: sensor detects set flow value
- For float-type flow meters with measuring tubes out of translucent material
- Measuring tube diameter: 5 to 14 mm
- Mounting with pressure screw
- 3 m connection cable
For non-heated flow meters FM1/10/40, clamping range from 5 to 14 mm
The patented forked light-barrier FA-... bi is used in gas and water analysis for flow monitoring in float-type flow meters with measuring tubes made of translucent material, e.g. Duran glass. Thanks to optical scanning, very low flow quantities can be detected by flow meters with non-metallic or very small (1 mm) floating balls.
Photoelectric bistable clamp‑on flow sensor type FA1bi, clamping range: 5 to 14 mm, 3 m connecting cable
