ATENG 11719. Rotameter
GENERAL DESCRIPTION
The Rotameter, “ATENG 11719”, is a device
developed for the study of flow measurement in fluid systems.
This unit allows students to analyze the operating principle of
variable area flowmeters with a float, which are widely used in
industrial and hydraulic applications. The inlet flow is supplied
through the Hydraulic Bench, “ATENG 12035”.
The ATENG 11719 consists of a vertical tube through which the
fluid flows upward. Inside, a float moves until it reaches an
equilibrium state between the upward force exerted by the
flow and its own weight. This equilibrium point allows for an
accurate measurement of the instantaneous flow rate, as the
position of the float is directly proportional to the velocity of
the flow.
PRACTICAL POSSIBILITIES
1.- Flow measurement.
Anodized aluminum structure and panel of painted steel.
