Vortex Flow Sensor WAFS 1102 – Compressed Air Flow Meter

The WAFS 1101 vortex flow meter is based on the Karman vortex principle to measure gas, steam, or liquid volume flow.

Its simplified structure, high reliability, and strong anti-pollution performance make it suitable for demanding industrial applications.

Integrated temperature and pressure sensing enables automatic density compensation to calculate mass flow using standard algorithms.

With digital spectrum analysis (DSA) and a high-sensitivity dual vortex sensor, the meter improves low-flow performance and helps reject vibration and electromagnetic disturbances.

Protection code: IP67. Explosion-proof structure is available for harsh environments (as applicable).
