FL 23.1 – Flow Meter Study

The goal of this item is the study and comparison of some of the different types of existing flow meters. The equipment incorporates gauges for more teaching and representative flow.
These flowmeters are a Venturi tube, rotameter, diaphragm, angle seat valve and a Pitot tube placed in series to allow direct comparison of results.
Through the realization of some of the practices of this item has failed to understand the behavior of fluids against certain laws of statics, dynamics, thermodynamics.
They may implement general principles such as the conservation of mass, or energy in a simplified and easily.
Besides regulating valve with variable flow rates allow you to work according to the needs of the practice.
The results are displayed in both the water column manometer and the supplied electronic differential. Through these gauges pressure values ​​are extracted at different strategic points of the equipment.
