Flow Meter Demonstration
The module consists of a Venturi meter, a flowmeter and an orifice
plate, installed in a series configuration to permit a direct comparison.
Several pressure taps are connected to a panel of eight tubes.
The flow control valve allows the variation of the flow rate through the
circuit, and its adjustment, along with the bench control valve, allows
for varying the system static pressure.
The pressure taps of the circuit are connected to an eight-bank
manometer, which incorporates an air inlet valve at the top manifold
which facilitates the connection to the hand pump.
This enables to adjust the levels in the manometer bank to a
convenient level to suit the system static pressure.
