    摘要: Dust filter (40) for a gas meter (1) which comprises an inlet channel (41) and an outlet channel (42) passing through one same first plane (P1), the dust filter comprising a filtering medium (43) wherein a hole is made, a cross-section of the filtering medium and a cross-section of the hole, along a second plane (P2) perpendicular to a thickness of the filtering medium, having for shapes, the shapes of a cross-section of the inlet channel and of the outlet channel along the first plane, the dust filter (40) thus being arranged such that, when it is installed in the meter (1), the gas, before entering into the measuring module, passes into the inlet channel through the filtering medium, and after exiting the measuring module, passes into the outlet channel through the hole.

    摘要: Illustrative embodiments of a meter box and couplings, either separately or in combination, are provided. An illustrative embodiment provides a valve coupling that is disposed through a wall of the meter box such that a first portion of the valve coupling extends exterior of the meter box and a second portion of the valve coupling extends interior of the meter box. An outlet coupling is disposed through the wall of the meter box such that a first portion of the outlet coupling extends exterior of the meter box and a second portion of the outlet coupling extends interior of the meter box. A telescoping tube is located in the meter box, extended into and movable relative to, and in fluid communication with, at least one of the second portion of the valve coupling and/or the second portion of the outlet coupling. The telescoping tube varies a distance between the valve coupling and the outlet coupling within the meter box.

    摘要: To enable accurate measurement of a flow rate of a gas flowing in a non-metallic tube. An ultrasonic flowmeter includes a first wedge member having a first angle, a second wedge member having a second angle, and a flow rate measurement unit that measures a flow rate of a gas based on a propagation time difference of a longitudinal wave excited by a tube. The first angle and the second angle are configured such that the tube excites both a longitudinal wave and a shear wave, and a mixing ratio of the shear wave to the longitudinal wave is 10% or less.
