HM 150.13 Methods of Flow Measurement Print page
Technical Description


  The experimental unit 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 measuring nozzle, orifice plate flow meter, venturi nozzle and rotameter.

  To determine the flow rate using a measuring nozzle / orifice plate flow meter and with the venturi nozzle, a differential pressure measuring device is required. This is included in the form of a multitube manometer so that the pressure curve along the venturi nozzle can also be displayed.

  The experimental unit is positioned easily and securely on the work surface of the base module HM 150. The water is supplied and the flow measured by HM 150. Alternatively, the experimental unit can be operated by the laboratory supply.
