Water flows through a Venturi tube, an orifice, a bend, or a kink. During this process the pressure loss is measured and compared with the flow through a straight pipe. On flumes experiments can be performed on the open channel and on a channel with weir structures. The Principles of Hydraulics is part of a series of units that enable experiments to be performed on flow processes with the aid of a computer. Here several areas of incompressible flows can be investigated. The Data Logging Unit is necessary for the operation of the Computer Linked Hydraulics Bench. If power data is to be displayed, the Digital Power Meter is required. After the recording of a pump characteristic curve, experiments on the topics of pipe flow and flow in open flumes can be performed. Two different weir structures are supplied.

The Electronic Pitot Sensor was designed as an accessory for the Computer Linked Air Flow Bench. Measuring connections on the sensor are connected to the pressure sensors on the Bench, the measurements made in this way enable the pressures across the diameter of the tube (= travel) to be displayed. The position of the measuring opening in the tube is output by a potentiometer as a voltage signal and can be displayed in a software package as travel in mm. With the vertically moving sensor, pressure measurements in the intake tube for the fan on the can be performed.
