The unit contains a Venturi tube made of a transparent acrylic material. When water flow rate increases, pressure at the throat is reduced complying with the Bernoulli equation until the vapour pressure of the liquid is reached. Under these conditions small bubbles of vapour are created and they collapse violently generating this phenomenon called cavitation.
The unit is equipped with two pressure gauges and a vacuum gauge in order to measure the pressure before and after the throat of the Venturi tube. In order to adjust the rate and the pressure there are two valves placed at the in inlet and outlet of the Venturi tube.
