The nozzle flow meter or any of the optional flow meters quickly andeasily fit into place between the adaptors in the base unit of the apparatus. For use by all kinds of engineering students, the Flow Meter Calibration apparatus compares and shows the accuracy and use of fundamental flowmeters. The manometers have a common manifoldfitted with an air valve. Students use the hand-pump to increase the air pressurein the manifold. The straight pipe gives a comparison of the true pressurelosses caused by the flow meters. Four water filled manometers show the pressure differences at the flow meterand across the overall flow meter assembly. This helps to explain the boundary layerand surface friction in pipes and flow channels. The optional Pitot Tube Flow Meter will alsoshow the velocity profile in a pipe.
