Abstract

The equipment automatically meters quantities of fluid, having a vessel accommodating the fluid with a bottom outlet and valve. The vessel (10) has a top cover (15) with an inlet union (21) for pressure equalisation by means of inflowing air. There is a jet-type opening (20) of predetermined cross-section in the union. It contains the resistance unit (30) of an anemometer circuit (40). At the output of this a voltage appears proportional to the flow speed and thus to the quantity of air, and is fed to the input of an analogue/frequency converter, emitting an alternating voltage or a succession of impulses of frequency proportional to this voltage. This is supplied toa counter circuit (60) for comparison with a reference value predetermined by an adjuster (70). The output of the counter circuit supplies a circuit (80) controlling the electrically-operated outlet valve (12).
