The apparatus consists of three very important flow measuring devices which are Venturi meter, orifice meter and rotameter. All three flow meters are extensively used
in industrial sector. Flowmeter Measurement Apparatus is designed to operate together with a basic hydraulic bench or any water supply. It is to familiarize the students with typical methods of flow measurement of an incompressible fluid.
The apparatus is able to demonstrate the flow measurement comparison by using a venturi device, orifice device and rotameter (Variable Area Flowmeter). The flow comparison can be further be used to compare against the flow measurement of the hydraulics bench which can be either by gravimetric or Volumetric Method, depending on the type of hydraulics bench in use.
