Vortex flow sensor 200
The flow sensors of Type 200 are based on the principle of the Kármán vortex street. The vortex flow sensors are free of moving parts, making them resistant to contamination. They are also characterized by a low pressure drop and high measurement accuracy.
Optional variants with an integrated temperature sensor are available.
- Low-cost product with very good accuracy
- Temperature-insensitive measuring principle
- Excellent media resistance (measuring element without media contact)
- Wider operating temperature range
- Low pressure loss
- Dirt-insensitive measuring element
- Temperature measurement directly in the medium optionally with PT1000 or NTC
- Drinking water approvals KTW, W270, ACS, WRAS
