<p>A device is described, for the adjustment of the flow rate of a liquid which circulates within thermal convectors or heat exchangers making up part of heating, conditioning or ventilation plants, or apparatus for the thermal treatment of products. The device comprises a body within which a movable shutter is provided, the position of which allows for adjusting the quantity of liquid flowing between at least an inlet duct and an outlet duct, the positioning of the shutter being obtained by way of a suitable actuator. The device comprises a control circuit and an instant flow rate and/or quantity meter of the liquid flowing in one of said ducts, for the automatic and continuous adjustment of the flow, by way of the appropriate positioning of the shutter.</p> |
