  • Publication number: 20230243682
    Abstract: A method of determining flowrate of a fluid (7) in a pipe is disclosed. The flowrate is determined using a flowmeter having first and second ultrasonic transducers (10; FIG. 8A) separated along the pipe by a given distance (D; FIG. 1) and inclined so that waves in the fluid propagate at a given path angle (?; FIG. 1). For a given inner pipe diameter (d; FIG. 1), there is a given integer number of reflections between the first and second ultrasonic transducers. The method comprises obtaining flow rate measurements using wave packets (18) corresponding to an integer number of reflections which is less than said given number.

  • Publication number: 20210371967
    Abstract: A method is described for selectively depositing a metallic layer (10) including one or more of copper, silver and gold. The method includes depositing a fluorinated layer (5) over a surface (1, 4). The fluorinated layer (5) has a thickness sufficient to substantially prevent deposition of the copper, silver and/or gold between the fluorinated layer (5) and the surface (1, 4) during a subsequent evaporation step using a given deposition rate. The method also includes forming the metallic layer (10) by evaporating, at the given deposition rate, the copper, silver and/or gold over the surface (1, 4) and the fluorinated layer (5). The copper, silver and/or gold preferentially adhere to the portions of the surface (1, 4) not covered by the fluorinated layer (s).
