Vortex flow sensor 240
The flow sensors of Type 240 are based on the vortex principle and deliver reliable measurement results for liquid media with varying specific viscosities – from antifreeze to drinking water. They operate without moving parts, ensuring long service life and high accuracy. These sensors are ideal for precise and stable flow measurements, even under challenging conditions.
The Type 240 stands out due to its exceptional resistance to high system pressures and media temperatures. It offers excellent accuracy and outstanding leak tightness. Covering a wide range of applications, it is suitable for small diameters, such as precise measurements in DN 6 pipelines, as well as large diameters in industrial processes.
Its compact design allows for direct mounting on the manifold, ensuring optimal space utilization.
- Wear-free and long-term stable sensor design
- Rugged design for system pressure up to 16 bar
- Up to 100 bar (pressure peaks)
- Media temperature measurement (optional)
- Hydrolysis-resistant sensor design
- Drinking water approvals
- UL 61010-1
- High long-term stability
