Abstract: A method for detection of a utility meter having been tampered with, in particular a water or heat meter having been tampered with, and a meter for detecting such tampering are provided. The utility meter comprises a flow measurement portion in which the flow of water is measured. The method comprises detecting a presence of air in the flow measurement portion and evaluating a fraud condition, wherein the fraud condition comprises that air is present in the flow measurement portion for a first period of time or more. In response to the fraud condition being evaluated as met, an alert is generated.

Abstract: The invention relates to a remote-reading device (3) for enabling the consumption of a meter to be read remotely and including a casing with a front wall (3A) and a side wall (3B). In the invention, the device also includes a specific solar radiation protective cover (4), said cover being disposed on the casing of the remote-reading device and including at least one covering wall (4A) for covering said front wall, the cover being secured to the casing of the remote-reading device. The device may be a remote-reading module (3) that is installed on a meter, or a remote-transmission relay (10).

Abstract: The invention relates to the technical field of oscillating piston volumetric fluid meters. The meter comprises a cylindrical measuring chamber including a lateral wall (2), a bottom (1) and a lid (3), a lower cylinder (4) and an upper cylinder (5) having the same diameter, which is less than the diameter of said chamber, an inlet orifice and an outlet orifice (8) for respectively admitting fluid to and evacuating fluid from said chamber, a cylindrical piston (11) disposed eccentrically and guided kinematically in said chamber and effecting an oscillatory movement in said chamber (30) as a result of the displacement of a volume of fluid, and a fixed partition (9) between said inlet orifice and said outlet orifice (8), lying radially between said lateral wall (2) and said lower and upper cylinders (4, 5), and lying axially between said bottom (1) and said lid (3), said lateral wall (2) including a vertical cavity (16) in the vicinity of said fixed partition (9).

Abstract: A volumetric fluid meter has a cylindrical measuring chamber with a lateral wall, a bottom (1) and a lid (3), a lower cylinder (4) and an upper cylinder (5), having the same diameter, which is less than the diameter of the chamber. An inlet orifice and an outlet orifice (8) respectively admit fluid to and evacuate fluid from the chamber. A cylindrical piston (11) is disposed eccentrically and guided kinematically in the chamber and effects an oscillatory movement in the chamber as a result of the displacement of a volume of fluid. A fixed partition (9) between the inlet orifice and the outlet orifice, lies radially between the lateral wall and the lower and upper cylinders, and lies axially between the bottom and the lid. The meter further includes a vertical groove (17) extending at least partly along the lower and upper cylinders and is in communication with one of the inlet and outlet orifices, and is situated in the vicinity of said fixed partition.
