FLOW MEASUREMENTS - HYDRAULIC FEEDING FROM BERNOULLI KIT
Allow the study of different devices for measuring the flow and their comparison permit the measurement of water flow with instruments placed one in series to another, verifying, thereby the degree of imprecision be made of transparent material for viewing the phenomena be installed on the hydraulic bench base, through an anodized aluminum frame with suitable PVC panels
The unit should be composed of:
Water inlet valve
Venturi meter:
in transparent plexiglass
Converging section from Ø 20mm to Ø 6 mm and a length of 50mm
Diverging section from Ø 6 mm to Ø 20 mm and a length of 100mm
Fitted with pressure taps upstream and downstream of the narrowing of the diameter
To read the pressure difference by means of piezometric tubes
Calibrated diaphragm:
In transparent plexiglass
Two flanged pipes (inner diameter 50 mm)
An orifice plate inner Ø 20 mm
Fitted with pressure taps located upstream and downstream of the diaphragm
Flow meter:
Conical tube section, on which is shown a graduated scale, and a float:
The balance between the thrust of the water flow and the
Weight of the float that moves inside the tube,
Allow the reading of the flow rate value
Measuring range 0 to 1200 l/h
Exhaust valve for regulating the flow rate inside the circuit
It works only if the Bernoulli's theorem kit is present
