The vortex flow meter is installed in the water circuit of the HM 500 trainer. It operates according to the principle of Von Karman vortex shedding. Downstream of a dam body in a flow, vortices alternately form which are separated off by the flow. The frequency of the vortex separation to both sides of the dam body is proportional to the flow rate. The separated vortices alternately generate local vacuum which is measured using capacitive pressure sensors. The pressure signals are converted and indicated as the flow rate on a display. The necessary connections are provided so that the pressure loss can be determined with the HM 500.
