Abstract:
The invention relates to an electronic flow controller ( 30 ) for applications in the HVAC field, said electronic flow controller comprising a one-piece valve body ( 31 ) which is penetrated by a flowing medium. The valve body is divided into a valve portion ( 31 a ) and a flow measurement portion ( 31 b ) along the flow direction, wherein a valve element ( 32 ) is arranged in the valve section ( 31 a ) for the control of flow, wherein said valve element can be controlled from the outside via a valve spindle ( 33 ), and wherein a measurement path ( 36 ) is formed in the flow measurement portion ( 31 b ) for determining the flow rate by means of ultrasound. In order to achieve a compact arrangement and a greatly simplified assembly, accesses ( 34 a, b ) for coupling and/or outcoupling ultrasound into or from the measuring path ( 36 ) are formed on the valve body ( 31 ) in the region of the flow measurement portion ( 31 b ). A control unit ( 62 ) is placed on the valve body ( 31 ), which comprises first means ( 27, 28 ) for actuating the valve element ( 32 ), said first means being in engagement with the valve spindle ( 33 ), and second means ( 29 a, b ) for emitting and/or receiving ultrasound signals which are acoustically coupled to the accesses ( 34 a, b ) for coupling and/or outcoupling ultrasound.

Claim (Index 1):
An electronic flow controller ( 10 ,  20 ,  30 ,  40 ,  66 ) for applications in the HVAC field, which comprises a one-piece valve body ( 11 ,  21 ,  31 ,  41 ) that is penetrated by a flowing medium and is sub-divided along the flow direction into a valve portion ( 11 a ,  21 a ,  31 a ,  41 a ,  67 ) and a flow measuring portion ( 11 b ,  21 b ,  31 b ,  41 b ), wherein in the valve portion ( 11 a ,  21 a ,  31 a ,  41 a ,  67 ) a valve element ( 12 ,  22 ,  32 ,  42 ,  76 ) is arranged to control the flow rate, which can be actuated from the outside via a valve spindle ( 13 ,  23 ,  33 ,  43 ,  75 ) and wherein in the flow measuring portion ( 11 b ,  21 b ,  31 b ,  41 b ) a measuring path ( 17 ,  26 ,  36 ,  46 ) is formed for determining the flow rate by means of ultrasound, characterized in that on the valve body ( 11 ,  21 ,  31 ,  41 ) in the region of the flow measuring portion ( 11 b ,  21 b ,  31 b ,  41 b ) access ports ( 14 a,b ,  15 a,b ,  24 a,b  34 a,b ,  44 a,b ) are formed for coupling in or extracting ultrasound into or out of the measuring path ( 17 ,  26 ,  36 ,  46 ), and that a control unit ( 62 ,  63 ,  68 ) is mounted on the valve body ( 11 ,  21 ,  31 ,  41 ), said control unit comprising first means ( 27 ,  28 ,  39 ) for actuating the valve element ( 12 ,  22 ,  32 ,  42 ,  76 ), said means being in engagement with the valve spindle ( 13 ,  23 ,  33 ,  43 ,  75 ), and second means ( 29 a, b ,  48 a, b ) for transmitting and receiving ultrasonic signals that are acoustically coupled to the access ports ( 14 a,b ,  15 a,b ,  24 a,b ,  34 a,b ,  44 a,b ) for coupling ultrasound in or out.
