Vortex flow sensor 230
The flow sensors of Type 230 are based on the principle of the Kármán vortex street. They offer a wide range of configuration options for electrical power supply and output interfaces.
The vortex flow sensors are maintenance-free due to their design without moving parts, making them resistant to contamination. Moreover, they are characterized by a low pressure drop and exceptionally high measurement accuracy. Additionally, the Type 230 provides high mechanical stability thanks to its red brass housing.
Optional variants with an integrated temperature sensor are available.
- Flow measurement optionally with voltage, current, pulse, or frequency output
- Excellent media resistance (measuring element without media contact)
- Optionally with integrated temperature measurement
- Large temperature operating range
- Large temperature operating range
- Low pressure loss
- Dirt-insensitive measuring element
- Drinking water approvals KTW, W270, ACS, WRAS
