HM 112 Hydrodynamics Trainer / PC Print page
Technical Description


The HM 112 trainer permits basic experiments on fluid mechanics. The experimental set-up is clearly laid out on a laboratory trolley. Due the use of a sealed water circuit, the trainer is particularly suitable for use in training and seminar rooms, and also lecture theatres. The system contains pressure and flow rate sensors that allow the values measured to be further processed on a PC. 6 different pipe sections and 8 components are used as measurement objects; of the 8 components, 5 represent components built into pipes, e.g. a membrane valve or dirt trap. 3 measurement objects are manufactured from Plexiglass and represent a venturi tube, a pitot tube, a metering orifice and a metering nozzle. With the PC data acquisition card and software included measured values can be displayed and evaluated on a PC.

Learning Objectives / Experiments

- Pressure and velocity measurements using

  venturi/pitot tube
- Flow rate measurements using nozzle and orifice
- Investigations on the fittings
  * comparative measurement of pressure loss, head

    loss and flow rate in relation to the degree of

- Investigations on the pipes
  * pipe flow with friction, pipe constriction, pipe

    enlargement, elbows and bends, drag coefficients


* Clear layout for experiments on the basic principles

  of fluid mechanics1
* Evaluation of measured data on a PC1
* Large number of measurement objects and pipe

  sections that can be changed
