ABSTRACT:
A circuit for dispensing fluid products, in particular coloring agents, paints and the like, comprises a pump (12) for delivering a fluid product, which pump can be activated selectively to send the fluid product to a dispensing duct (16) and a valve (18) which is disposed on the dispensing duct (16) and which can be opened to dispense the fluid product. A control system (28) is able to control the activation of the pump (12) in order to dispense a predetermined quantity of the fluid product. A sensor (24) is provided to detect the opening of the valve (18) and thus the effective start of the dispensing operation to be signalled to the control system (28).
