    摘要： A moving body surface or paper web (1) to be investigated is irradiated at at least one irradiation site by 3 laser light sources of a surface structure measuring device (FOS1, FOS2). Reflected and scattered light is detected and evaluated in order to calculate ellipse points. An ellipse major axis ratio corresponding to a fiber orientation ratio, and a fiber orientation angle are calculated from the ellipse parameters thus obtained. Identical measurements and calculations are carried out periodically on an isotropic sample (NO) and a sample (Nx) having a fiber orientation similar to that of the body surface to be measured, in order to calibrate the measurements at the body surface (1).

    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： Described is a method and a device for more accurate measurement of a gas supply with a gas meter. A consumption-weighted correction factor is determined by weight averaging of a sensor error factor of the gas meter with a consumption profile characteristic of the gas supply location and the measuring signal is converted using the correction factor. Embodiments relate inter alia to: operation of the gas meter as volume, mass or energy meter; formulae for determining the correction factor with sensor error factors and consumption profiles relative to volume, mass or energy; and measuring signal correction in the case of a non-registering or registering gas meter. Advantages are inter alia: subsequent customer-specific measuring signal correction; no additional measuring complexity; and improved measuring accuracy, in particular improved energy measurement by means of compensation for inherent deviations of the energy signal in the vase of heat value variations.
