Flow Meter Demonstration Unit

A flow control valve permits variation of the flow rate through the circuit.
Pressure tapping’s 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.
Flow Meter Demonstration Apparatus contains different flow rate measurement devices that are clearly laid out with the associated pipework on a metal sheet.
So that the function can be observed, the measuring devices are made of transparent plastic.
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 is included in the form of a multiple tube manometer so that the pressure curve along the venturi flow meter can also be displayed.
The apparatus is placed on the Hydraulics Bench; this provides the water supply to the unit.
