Materials

  • Housing: polypropylene
  • Rotating vane: polypropylene
  • Axle/bearing: sapphire
  • Vane mount: polysulfone

Operating Principles
The medium flows through a specially shaped flow housing and causes a vane to rotate. This rotary motion is sensed by optoelectronics in a non-contacting manner, and converted to an asymmetric frequency signal or an analogue signal. A frequency divider with symmetrical output is available as an option. The frequency is proportional to the flow velocity. The vane is sapphire-supported: this ensures a high degree of linearity and long service life.
