For use by all kinds of engineering students, the Flow Meter Calibration apparatus compares and shows the accuracy and use of fundamental flow meters.
The nozzle flow meter (included) or any of the optional flow meters quickly and easily fit into place between the adaptors in the base unit of the apparatus. Four water-filled manometers show the pressure differences at the flow meter and across the overall flow meter assembly. The manometers have a common manifold fitted with an air valve. Students use the hand-pump (included) to increase the air pressure in the manifold. This ‘offsets’ the manometer measurement (adjusts the datum).
The straight pipe (included) gives a comparison of the true pressure losses caused by the flow meters.
The optional Pitot Tube Flow Meter (H40a) will also show the velocity profile in a pipe. This helps to explain the ‘boundary layer’ and surface friction in pipes and flow channels.

- Losses and k value
- Calculation of the coefficient of discharge
A mobile self contained bench with recirculating water supply. It provides water at different flow rates direct to experiments and includes digital flow display for hydraulic and fluid mechanics experiments.
A mobile, vertical panel featuring various pipe configurations to demonstrate flow and losses in different pipes fittings and valves. Includes Pitot tube, Venturi and orifice meters for flow measurement.
A Venturi meter, an orifice plate meter and a rotameter that demonstrates typical methods of measuring the flow of an incompressible fluid and shows applications of Bernoulli's equation.
