  • Hard copy user manual

The losses in a pipe system kit (FM106) is a bench top kit which is designed to illustrate the pressure losses in pipes, piping elements and shut-off devices. In addition to using the differential pressure method for measuring the flow rate.

  • The educational unit contains six different pipe sections capable of being shut off individually.
  • The pipe sections are equipped with piping elements such as sudden contraction, sudden enlargement, Y-pieces, T-pieces, corners and bends.
  • In one pipe section, different shut-off devices and measuring objects are installed.
  • The unit is supplied with different measuring objects for determining the flow rate according to the differential pressure method.
  • The measuring objects are made of transparent material and provide excellent insight into the inner structure.
  • The measuring objects include Venturi nozzle, orifice plate flow meter and measuring nozzle.The shut-off devices include angle seat valve and gate valve.
  • The pressure measuring points in the piping system are designed as annular chambers. This creates a largely interference-free pressure measurement.
  • The opening characteristic of the shut-off devices are also recorded. The pressures are measured with tube manometers.
  • The experimental unit is positioned easily and securely on the work surface of the main hydraulic unit.
  • The water is supplied and the flow rate measured by the main hydraulic unit.
