1. A hydraulic separator for hydronic systems for heating and/or cooling, comprising:
a hollow body with a casing, internally defining a chamber;
at least two first through openings for the delivery of a fluid, and at least two second through openings for the return of the fluid, said first through openings and said second through openings being made on said casing of the body and operable to establish fluidic communication between the chamber and to external circuits by hydraulic connection;
at least one mobile element separating the chamber of the body into a first portion and a second portion, to reduce fluidic communication between said first portion and said second portion of the chamber;
a control unit;
at least one actuator connected to the at least one mobile element and positioned in communication with and operably controlled by the control unit; and
a plurality of electric or electronic sensors or transducers connected to the control unit configured to measure a physical parameter of the fluid, at least one sensor of the plurality of sensors being positioned at or between at least one of the first through openings and at least one of the second through openings;
wherein said sensors send a pressure difference signal to the control unit corresponding to the physical parameter of the fluid measured by said sensors;
wherein said at least one mobile element comprises a butterfly valve made of a thermal insulating material to limit thermal heat conduction between the first portion of the chamber and the second portion of the chamber;
wherein the at least one mobile element is actuated by the actuator; and
wherein the control unit controls the actuator responsive to the pressure difference signal.
