MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202647094663 A) filed by Huba Control AG on August 05, 2026, for Lamb Wave Ultrasonic Flow Meter.
Inventors include Anliker, Peter; and Menzi, Stefan.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: A flow meter (10) is described, comprising a housing (1) with a longitudinal axis (L) and a flow channel (2), the flow meter (10) comprising a first and a second piezoelectric transducer (3.1, 3.2) arranged at an outer surface (1.3) of the housing (1) and each configured to generate an acoustic wave with a wavelength ? in the housing (1), wherein the housing (1) has a thickness d1 at the piezoelectric transducers (3.1, 3.2) and a thickness d2 at an opposite side (1.5) of the flow channel (2), the thicknesses d1 and d2 being smaller than the wavelength ? of the acoustic wave such that a Lamb wave (Lb1, Lb2, Lb3) is excitable in the housing (1), wherein the piezoelectric transducers (3.1, 3.2) are each configured to receive an acoustic wave in the form of a Lamb wave (Lb1, Lb3) from the housing, wherein the piezoelectric transducers (3.1, 3.2) each exhibit a height (H) and a width (W), wherein the height (H) is larger than the width (W).
