HM 150.13 Methods of Flow Measurement
Education / GUNT Hamburg / Fluid Mechanics and Hydrology / Fundamentals of Fluid Mechanics /


The HM 150.13 Flow Meter Demonstration Apparatus contains different flow rate measurement devices that are clearly laid out with the associated pipework on a metal sheet. So that the function can be observed, the measuring devices are made of transparent plastic. The flow rate is measured using a nozzle, orifice, venturi flow meter and variable-area flow meter. To determine the flow rate using a nozzle/orifice and with the venturi flow meter, a differential pressure measuring device is required. This is included in the form of a multiple tube manometer so that the pressure curve along the venturi flow meter can also be displayed. The apparatus is placed on the HM 150 Basic Hydraulics Bench, this provides the water supply to the unit.
