Abstract
The invention relates to an electronic flow controller () for applications in the HVAC field, said electronic flow controller comprising a one-piece valve body () which is penetrated by a flowing medium. The valve body is divided into a valve portion () and a flow measurement portion () along the flow direction, wherein a valve element () is arranged in the valve section () for the control of flow, wherein said valve element can be controlled from the outside via a valve spindle (), and wherein a measurement path () is formed in the flow measurement portion () for determining the flow rate by means of ultrasound. In order to achieve a compact arrangement and a greatly simplified assembly, accesses () for coupling and/or outcoupling ultrasound into or from the measuring path () are formed on the valve body () in the region of the flow measurement portion (). A control unit () is placed on the valve body (), which comprises first means () for actuating the valve element (), said first means being in engagement with the valve spindle (), and second means () for emitting and/or receiving ultrasound signals which are acoustically coupled to the accesses () for coupling and/or outcoupling ultrasound.
