Abstract: An ultrasonic flow measurement system (1) comprising a flow tube (11), an ultrasound damping layer (12), an ultrasound transmitter (13) covered by the ultrasound damping layer, and an ultrasound receiver (14) covered by the ultrasound damping layer, characterised in that the ultrasound damping layer comprises: —a first damping portion (121) that is at least partially positioned in between the ultrasound transmitter and the ultrasound receiver as well as—a second damping portion (122) that is at least partially positioned in between the ultrasound transmitter and the ultrasound receiver, wherein the first damping portion and the second damping portion of the ultrasound damping layer are spaced apart from each other by a distance (d) in an axial direction (A) of the flow tube.

Abstract: The present invention relates to street sweeper. According to a first aspect of the invention, different mechanisms are disclosed for controlling the movement of the brush-holder arms in a horizontal plane, while also damping side and front impacts. According to a second aspect, a sweeper is disclosed, in which the movement of the brush-holder arms (3) in a vertical plane is imparted by a set of four profile members, arranged in two pairs which each forms a deformable parallelogram, wherein the deformation of the parallelogram is actuated by a jack (25) and the own weight of the sweeping arm. The jack is configured to remain below the upper profile members (11) of the two pairs when the brush-holder arm is raised to its maximum height. According to a third aspect, the suction turbine (103) is arranged in such a way that load losses are reduced during the operation of the sweeper.

Abstract: The invention relates to a thermal-type flow sensor (1) for a flow meter, comprising a main channel part (3b) with a main channel (3) for a medium whose flow is to be determined, a sensor tube (4), having a first tube portion (5), a second, opposite tube portion (8), a sensing portion (11) connecting the first and second tube portions, at least two sensing or heating elements (12) for measuring a temperature differential or a power differential in the sensor tube, a thermally conductive frame element (13) in contact with at least the first tube portion, the second tube portion as well as the main channel part, configured to equalize temperature gradients, wherein thermally conductive frame element (13) is a printed circuit board (PCB) (14).
