Ultrasound sensor arrangement, apparatus and method of transmitting of ultrasound

An ultrasound sensor arrangement comprises a plurality of ultrasound transmitting elements (102') of an ultrasound transmitter (102) and an ultrasound receiver (104) with at least two ultrasound receiving elements (106). The transmitter (102) and the receiver (104) are integrated together on a chip (100) which can attached on or inserted as a part of solid material of a duct (108) within which fluid flows for the receiving elements (104) to receive the ultrasound signal, which is transmitted by the transmitting elements (102) into the flow, as a reflection from the duct (108). The transmitting elements (102) are between at least two receiving elements (106) of the plurality of receiving elements (104), where a line (LI) of the flow and a line (L2) between said at least two receiving elements (106) are parallel or have a predetermined angle therebetween, and/or the at least two ultrasound receiving element of the ultrasound receiver (104) are between two groups (102A, 102B) of the ultrasound transmitter elements of the ultrasound transmitter (102), where a line (LI) of the flow and a line (L2) between said two groups (102A, 102B) of transmitting elements are parallel or have a predetermined angle therebetween.
