Description

The bench STL200 allows the study of the losses of charge of various components and to measure flow rates by the mean of Bernoulli's theorem on deprimogenic organs (Venturi and orifice plate).

For this, water circulates in a hydraulic circuit comprising the classic elements of an installation (elbows, sudden contraction and enlargement, orifice plate and venturi), to measure the pressure losses using a bank of water manometer tubes.

The bench is equipped with a flowmeter which makes it possible to study the relationship between the flow rate and the pressure drop on each element.

The robust design of this equipment makes it perfectly suited for school use.

Its anodized aluminum structure on wheels makes it very robust as well as a great flexibility of integration into your premises. The manufacture of this equipment meets the European machine directive
