Descriptions:

• The equipment consists of a Venturi meter, variable area meter and orifice plate, installed in a series configuration to permit direct comparison.
• A hand pump facilitates pressurization of the manometers.
• A flow control valve permits variation of the flow rate through the circuit.
• Pressure tappings are incorporated so that the head loss of each flow meter may be measured.
• 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.
