Description
It includes:
  • Static fluid panel and manometry.
 It consists of different types of piezometric tubes and level measuring elements such as graduated scales and limnimeter. Transparent tank where we will pour water, and through the different valves and pipes, the water is brought to the different columns.
One of the water columns has a system to tilt it, so that the effect of the different possible inclinations can be clearly visualized. Both in the different columns and in the deposit, it exist a graduated scale to visualice directly the height of the water.
It also includes a limnimeter for accurate water measurement.
  • Calibrator of dead-weight manometer.
The objective to be achieved with this equipment is to determine the reading error of a Bourdon manometer since, to guarantee the accuracy and precision of these manometers, it is necessary to perform calibration processes and continuous evaluation of the instrument.
For this purpose, procedures will be carried out to verify accuracy and precision using a deadweight calibrator.
  • Bourdon manometer panel (manometer and vacuometer)
Learning Objectives
 A wide range of practices and experiences can be performed, some of which are listed below:
  • Study and testing the hydrostatic paradox.
  • Comparison between absolute and relative pressure.
  • Use of the piezometric tube.
  • Pressure measurement with the following types of manometers:
    • in “U”
    • inverted “U”
    • Titled
    • Differentials
    • Bourdon
    • Bourdon vacuometer
  • Use of limnimeter to messure the water level.
  • Use of graduated scales to determinate the water level.
  • Study of the air influence inside the manometers.
  • Study of load loss.
  • Functioning manometer explanation.
  • Manometer calibration.
