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 Specifications: Venturi meter, variable area meter and orifice plate with control valve Pressure tappings to measure head loss from each meter Manometer range: 0 to 440mm Number of manometer tubes: 8 Orifice plate diameter: 20mm Variable area meter: 2 to 20 litres/min
