Miniature flow rate sensor for gas RAPIFLOW®
- Model No.
- FSM
Discontinued some variations
- Industry
- Semiconductor manufacturing process (post-process)
Miniature flow sensor for compressed air and nitrogen gas. It is ideal for checking suction of electronic parts and the like thanks to its light weight and high-speed response.

- Features
[Miniature/lightweight] (FSM-X Series)
Compact body enabled by separating the sensor head.
Reduced volume by 52% compared to conventional products, light weight of 4 g and ultra-thin 8 mm are realized.
It is available as sensor head only and with flow path block.[Non-linear characteristics] (FSM-X Series)
Since the analog output has non-linear characteristics, the resolution in low flow rate range is improved.[High-speed response] (FSM-V / FSM-X Series)
5 ms high-speed response has made possible a design once abandoned[Bi-directional measurement] (FSM-V / FSM-X Series)
Bidirectional measurement is possible, making it ideal for suction confirmation.
