PRODUCT
HM 500.10 Paddle Wheel Flow Meter
Education / GUNT Hamburg / Fluid Mechanics and Hydrology / Steady Incompressible Flow /
description

The vane impeller flow meter is installed in the water circuit of the HM 500 trainer.
  The kinetic energy of the flowing water causes angular rotation of the paddle wheel, the frequency of which is proportional to the flow rate of the water. The angular frequency is measured by a ring magnet and converted by a Hall sensor into an analogue voltage signal. This voltage signal corresponds to the flow rate of the fluid.
  A display indicates the flow rate. The necessary connections are provided so that the pressure loss can be determined with the HM 500. The transparent front makes the paddle wheel visible, thus aiding understanding of the operating principle.

 

Learning Objectives / Experiments

- familiarisation with the principle of operation
- flow measurement
