摘要： A fire prevention safety device for a gas meter (3) has closure means (4, 4′, V) that can be activated by heat to interrupt the gas supply into the gas meter (3) in the event of a fire. The gas meter (3) is arranged in a bypass (2) of a gas pipe (1). At least one of the aforementioned closure means (4, 4′, V) for interrupting the gas supply is in each case arranged in the bypass (2) in the flow direction upstream and downstream of a sensor (31) belonging to the gas meter (3). The device permits a cost-efficient, simple and effective fire prevention safeguard, in particular for electronic gas meters.

摘要： The invention relates to a differential pressure means and a gas meter arrangement for precisely measuring a gas consumption by means of a gas meter. A previously known gas meter is disposed in a bypass comprising a differential pressure means in the gas pipe for measuring a volumetric flow rate inside the gas pipe. According to the invention, the differential pressure means comprises flow ducts having decreasing diameters as the radial position increases starting from a central axis of the differential pressure means. Examples of execution include inlet ports and/or outlet ports of the flow ducts which are provided with a specific countersink angle (α), and an equidistant, concentric arrangement of flow ducts on the cross-sectional area of the differential pressure means. The invention has the advantage of increasing the differential pressure at a low volume flow rate, reducing the differential pressure at a high volume flow rate, and generally creating an improved linearity across the entire measurement range between the volume flow rate in the bypass and the volume flow rate in the gas pipe, among other things.

摘要： The invention relates to a method and a device for measuring a gas consumption by means of a gas meter. A gas meter with thermal mass flow sensor for determining mass flow signals (SM) and with a calibration as energy meter for outputting energy value signals (SE) is known. According to the invention, a gas type is determined by the gas meter insofar as combustible and non-combustible gas mixtures are differentiated. The gas meter is operated, in the case of a non-combustible gas mixture, with calibration in mass or standard volume units (l/min) and, in the case of a combustible gas mixture, with calibration in energy units (kWh). Embodiments concern inter alia: measurement of a gas parameter (λ, α, c, η) of the gas or determining the gas type; gas quality sensor with an identical construction to thermal flow sensor; measuring intervals lengthened in the case of non-combustible gas and shortened in the case of combustible gas. Advantages are inter alia: reliable energy measurement because of automatic differentiation between non-meterable gas and high-quality useful gas; detection of manipulation attempts; and automatic heat value tracking even without heat value measurement.
