Vortex flow sensor 236
The flow sensors of Type 236 are based on the principle of the Kármán vortex street.
They differ from their counterpart, the Type 210, through their brass housing. The vortex flow sensors of Type 236 offer a wide range of configuration options for electrical power supply and output interfaces. Due to their maintenance-free design without moving parts, the sensors are resistant to contamination. Furthermore, they are characterized by a low pressure drop and exceptionally high measurement accuracy.
Optional variants with an integrated temperature sensor are available.
- Temperature-insensitive measuring principle
- Excellent media resistance (measuring element without media contact)
- Optionally with temperature measurement
- Low pressure loss with high measurement accuracy
- Dirt-insensitive measuring element
- Temperature measurement directly in the medium
- Drinking water approvals KTW, W270, ACS, WRAS
- High measurement accuracy
