HM 120 Pipe Fitting Loss Demo Panel Print page
Technical Description


The experimental arrangement is clearly laid out on a demo panel. The panel is fitted to a laboratory trolley and is thus flexible in use. Only a supply of cold water and a drain are required for operation. For the investigations on the pipes, 10 different pipe sections are provided in which measuring connections with annular chambers are incorporated. The measuring connections are connected to the corresponding measuring equipment using hoses. The pipes can be individually selected for the experiments using connecting hoses. For pressure measurements, a double manometer, manometer panel and a battery operated electronic differential pressure measuring unit are provided. The flow rate is indicated on a variable-area flowmeter. An instruction manual with detailed description of the theoretical background is supplied.
