F1-10 Accessory
F1-21 Flow Meter Demonstration - Issue 19
This accessory is designed to introduce students to three basic types of flow meter.
ORDERING SPECIFICATION
• Venturi meter, variable area meter and orifice plate with control valve
• Pressure tappings to measure head loss from each meter
• Supplied with manometer board with eight tubes
• Quick release fitting for easy connection to hydraulics bench
• Educational Software available as an option
TOPDescription
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 volumetrically each flow meter.
