Flow Meter Demonstration.
Flow 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 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
volumetric each flow meter.
Experimental Capabilities:
Directly comparing flow measurement using a Venturi meter, variable area meter and orifice plate
Calibrating each flow meter using the volumetric measuring tank of the bench
Comparing pressure drops across each device
