1. A flow control device (1) for an HVAC fluid transportation system (2), the flow control device (1) comprising:
a flow tube (10) formed in one piece;
flow measurement system (11) integrated with the flow tube (10) and configured to measure a volumetric flow of fluid (φ) through the flow tube (10); and
an electronic circuit (12) arranged in a fixed fashion on the flow tube (10) and connected electrically to the flow measurement system (11);
wherein the flow control device (1) further comprises a control signal output terminal (13) attached to the flow tube (10) and connected to the electronic circuit (12), and the electronic circuit (12) is configured to generate and apply on the control signal output terminal (13) an actuator control signal, using the volumetric flow of fluid (φ) measured by the flow measurement system (11), for an actuator (23), arranged outside the flow tube (10) of the flow control device (1), to actuate a valve (22) of the HVAC fluid transportation system (2),
wherein the flow control device (1) further comprises a (15) an actuator data input terminal (18) attached to the flow tube (10) and connected to the electronic circuit (12), and the electronic circuit (12) is further configured to generate the actuator control signal further using actuator data received on the actuator data input terminal (18), and
wherein the electronic circuit (12) is configured to determine an actuator type from an actuator identifier received in the actuator data input terminal (10), and to generate the actuator control signal using the actuator type.
