Abstract: A home use Video Tape Recording system with a built in chronometer is a relatively cheap item of laboratory equipment which is used to great advantage in hydraulic model studies. The combined reliabili-ty and efficiency of this method is a marked improvement on alternative systems. The flow velocity errors are a1so smaller (about 5%) than errors which are conmon with single velocity measurements with a micro-propeller. the equipment required and the practical implementation of the method is given in the paper.
