VN Series is an electromagnetic flow sensor designed for small pipe diameter and low flow.
- Electromagnetic flow sensor without moving parts suitable for use in machines.
- With absence of moving parts, there is less failure due to its contaminants.
- Low-pressure loss
- No straight pipe required, compact design, and easy to install.
