This application provides an adaptive temperature-controlled heat metering device and its operation method, belonging to the technical field of heating systems. It includes a calculation and control unit, an inlet water pipe, a heat dissipation end, and a return water pipe. Temperature sensors are installed in both the inlet and return water pipes. The regulating valve assembly includes an active valve, a floating regulating chamber, and a passive valve. The floating regulating chamber is divided into regulating chamber one and regulating chamber two by a floating piston, with a regulating spring clamped between the floating piston and regulating chamber two. The inlet end of the active valve is connected to regulating chamber one, and the outlet end is connected to regulating chamber two. The valve core of the passive valve is fixedly linked to the floating piston. Due to the self-balancing effect of the floating piston, the pressure difference across the active valve remains constant regardless of whether the opening of the active valve increases or decreases, preventing whistling noise. The calculation and control unit can obtain the system flow rate value based on the valve orifice area and the aforementioned pressure difference value, and realize heat metering based on the supply and return water temperatures measured by the supply and return water temperature sensors.
