Orifice and Venturi Meter Demonstration

Orifice and Venturi Meter Demonstration

The equipment consists of a Venturi meter, variable area meter and orifice plate, installed in a series configuration to permit direct comparison.
A flow control valve permits variation of the flow rate through the circuit.
Pressure tappings are incorporated so that the head loss characteristics of each flow meter may be measured.
These tapping’s are connected to an eight-tube manometer bank incorporating a manifold with an air bleed valve.
A hand pump facilitates pressurization of the manometers.
The circuit and manometer are attached to a support framework, which stands on the working top of the Hydraulics Bench.
The bench is used as the source of water supply and for volumetrically calibrating each flow meter.
This enables to adjust the levels in the manometer bank to a convenient level to suit the system static pressure.
