F1-21-MKII Flow Meter Demonstration
This accessory is designed to introduce students to three basic types of flow meter:
-
- Venturi meter
- Variable area flowmeter (Rotameter)
- Orifice plate
- 8 pressure tappings are connected and displayed on the manometer bank to visualise pressure profiles
Description
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 an 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 volumetrically calibrating each flow meter.
- Optional Pitot Static Tube
