Vortex flow sensors for Heatpumps / Plastic version

Type VVX20 LowFlow

  • Increased efficiency of the heat pump by controlling even at low flow rates
  • The low pressure drop of the sensor can help to reduce the power consumption of the pump
  • The compact design allows the use even if only little space is available

The SIKA VVX LowFlow is used for the flow measurement in Heatpumps.

Behind a flowed-around bluff body, counter-rotating and mutually offset vortices arise. The vortices detach at the edges of the bluff body and form a Kármán vortex street in the flow. The distance between the individual vortices is constant. The frequency at which the vortices flow past a sensor depends on the flow velocity and is proportional to the flow rate. The sensor detects the vortices, which are converted into an electrical frequency signal.
