Abstract
A flow control device (1) for an HVAC fluid transportation system comprises a flow tube (10) formed in one piece, a 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). 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). 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 actuating a valve of the HVAC fluid transportation system (2) arranged outside the flow tube (10) of the flow control device (1).
