Description
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 waterfilled 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.
The Flow Meter Calibration works with TecQuipment’s Digital Hydraulic Bench (H1F, available separately)* and stands on the hydraulic bench worktop.
Water enters from the left of the product and leaves at the right through a flow-control valve that sets the flow rate. This valve is downstream, so it does not cause any upstream turbulence.
Essential Base Unit
• Digital Hydraulic Bench (H1F)*
*This product will also work with existing TecQuipment Gravimetric and Volumetric Hydraulic Benches (H1 and H1D)
