Abstract: A consumption meter 100 for measuring consumption data of a supplied utility is provided, the consumption meter comprising: a housing 110 with an opening 112, where the housing 110 forms a closed compartment when the opening 112 of the housing 110 is closed with a cover 120; a communication module 130 provided in the closed compartment; a front plate 140 provided in the closed department and arranged adjacent to the cover 120, wherein the front plate 140 has a first front plate surface 142 facing the cover 120, and a second front plate surface 144 facing opposite; and an antenna comprising an antenna body 150 with an antenna conductive element 154, which is connected to the communication module 130; wherein the front plate 140 has an indentation 146 arranged between the first and the second front plate surfaces 142, 144, and wherein the antenna body 150 is arranged in the indentation 146. The consumption meter 100 provides an antenna with a high transmission performance. Further, the antenna is mechanically supported, and is arranged inside the closed compartment, eliminating the need of any feedthrough across the housing wall.

Abstract: A flow meter (1) includes a flow tube (3) and sensors (19a, 19b), that generate signals for measuring a fluid flow through the flow tube. An electronics housing (5) accommodates a battery (23) and a printed circuit board, PCB (15). The PCB is equipped with electronics. A pair of elongate connector elements (29) electrically connect axial end contacts (27) of the battery with the PCB for powering the electronics and/or sensors by the battery. The battery is arranged at a distance (D3) to the PCB. The pair of elongate connector elements includes a first end section (31), connected to the PCB, a contact section (33), connected to one of the end contacts of the battery, and a second end section (35). The electronics housing includes inward protrusions. The second end sections of the pair of elongate connector elements abut axially against the inward protrusions to fix the battery axially.

Abstract: An ultrasound flow meter includes a housing (1) which includes a channel (2) for leading through a fluid, which fluid flow rate is to be measured. Two ultrasound transducers are arranged on the wall which delimits the channel (2), within the housing (1). The ultrasound transducers are fixed within the housing by a non-releasable snap connection and/or clamping connection.
