ABSTRACT:
A flowmeter for the quantitative measurement of small rates of flow of fluids (liquids and gases), comprising a hermetically sealed housing having two parallel walls, at least one of these being transparent, a scale being provided on said transparent wall, a thin flexible resilient vane attached by one of its ends to a sidewall of the housing so as to divide the inner space into two parts, inlet means for the fluid being provided in sidewall connected to one of these parts, outlet means being provided in a sidewall of the other part, the flexible vane having an area protruding into the inner space of the housing equal to essentially the inner cross-section of the housing at the position of the vane when no fluid is flowing. Preferred shapes of the housing are (in side view) a semi-circle, half an ellipse or a triangle.
