Flowmeter Measurement Apparatus .
The Flowmeter Measurement Apparatus 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 tappings are connected to an eight tube
manometer bank incorporating a manifold with air bleed valve.
Pressurisation of the manometers is facilitated by a hand pump.
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 calibrating volumetrically each flow
meter.
