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.
Specification:-
- Venturi meter, variable area meter and orifice plate with control valve
- Supplied with manometer board with eight tubes
- Pressure tappings to measure head loss from each meter
- Quick release fitting for easy connection to hydraulics bench
