Tesca Vortex Flow Meter makes it possible to study different methods of volumetric and mass flow measurement, as well as to compare continuous and intermittent methods. This module includes two continuous and two intermittent methods to carry out the experiments. The continuous methods include a vortex flowmeter and a variable-area flowmeter (or rotameter). A series of oscillating vortices, where the oscillating frequency is proportional to the flow rate, are generated in the vortex flowmeter. Dye or colouring is used to visualize such vortices. Intermittent methods include the measurement of volumetric and mass flows. A precision scale is used to measure the mass flow and compare the measurements. The water supply may be provided either from the Hydraulics Bench 32096
