Embodiment Construction

[0037] Figure 1a , Figure 1b and Figure 1c A compact ultrasonic flow meter 1 according to one embodiment of the invention is shown. The flow meter comprises a flow tube 11 having a flow hole 111 for passing a fluid between an inlet 112 and an outlet 113 . The flow meter housing 12 is formed as an integral part of the flow tube, thereby providing a compartment for instrumentation components arranged at the flow tube for measuring the flow of fluid flowing in the flow bore. The flowmeter housing is closed by a cover 121 consisting of a locking ring 122 and a transparent cover element 124 . A sealing element 123 is arranged between the cover and the flowmeter housing to provide a hermetic seal.

[0038]Inside the flow meter housing, a printed circuit board (PCB) 13 is arranged which includes a processor 135 for controlling the operation of the flow meter. The PCB further includes instrumentation circuitry (not shown) and two ultrasound transducers 14 mounted on its undersi...

Abstract

Compact ultrasonic flowmeter for measuring flowrate and other fluid related data, comprising: a flow tube with a flow bore for passage of the fluid between an inlet and an outlet; a flowmeter housingassociated with the flow tube; a printed circuit board arranged in the flowmeter housing and including a processor for controlling operations of the flowmeter; a meter circuit including two or more ultrasonic transducers provided on the printed circuit board and configured for operating the ultrasonic transducers to transmit and receive ultrasonic wave packets through the fluid; a display mountedon the printed circuit board and configured for displaying a measured flowrate and other fluid related data; and one or more battery packs for powering flowmeter operations including at least the processor and the meter circuit and the display; wherein the processor and the ultrasonic transducers are surface mounted on a lower side of the printed circuit board and the display is mounted on an upper side of the printed circuit board.

Description

technical field [0001] The present invention relates to an ultrasonic flow meter for measuring flow and other fluid related data, the flow meter includes a flow tube and a flow meter housing containing a plurality of flow meter components including a Surface components of printed circuit boards. Background technique [0002] Electronic or steady-state flow meters, such as ultrasonic flow meters, are increasingly used as utility meters for measuring water consumption. Ultrasonic flow meters offer the advantage of having no moving parts over traditional mechanical flow meters. Another advantage is the electronic nature of ultrasonic flow meters. Since the ultrasonic flowmeter includes a power source, usually a battery, for powering the measuring circuit, it is also possible to integrate radio communication means for external communication. Additionally, ultrasonic flow meters typically include on-board processing capabilities so that data processing can be performed within ...
