Patent number: 12339149Abstract: A clamp-on ultrasonic flowmeter includes pairs of ultrasonic transducers arranged on an exterior of a pipeline, and an electronic measuring/operating circuit for operating the transducers and for registering and evaluating measurement signals and for providing measured values of volume flow or flow velocity. The pairs are implemented as 1-traverse or 2-traverse pairs. One-traverse pairs are arranged on opposite sides of the pipeline, and 2-traverse pairs are arranged on a same side of the pipeline. At least three pairs are arranged on the pipeline and are distributed peripherally. Adjoining pairs of a number of pairs have an inner angle down to a minimum inner angle (MIA) between one another measured about a pipeline axis, which minimum inner angle obeys the following relationship: MIA=360°/(T*N*F(T,N)) with T as number of traverses and F(T,N)=0.38+0.62*T+(0.048?0.01*T{circumflex over (?)}2)*(N?2){circumflex over (?)}2.Type: GrantFiled: June 16, 2021Date of Patent: June 24, 2025Assignee: Endress+Hauser Flowtec AGInventors: Oliver Berberig, Thomas Fröhlich, Beat Kissling, Quirin Müller, Klaus Bussinger
