    摘要: A method and a sensor (1) for oil-in-water measurement, in particular for the oil industry. In an electric measuring cell (7, 12) a capacitance is measured as a measure of an oil concentration in the water flowing through or in the accumulation filter (16, 16a, 16b). In order to reduce the maintenance requirement, the measuring cell (7, 12) is automatically calibrated at recurring time intervals with clean water (FIG. 1) and/or flushed with water, possibly oil-contaminated, in the back-flushing direction (FIG. 2). Advantages of the invention are reduced signal drift, improved long-term reliability and a long service life without monitoring or filter exchange. Important exemplary embodiments relate to: a measuring cell (7, 12) with a long measuring and short flushing/calibration cycle, a measuring cell (7, 12) with a plurality of accumulation filters (16a, 16b) whose measuring cycles supplement one another in time, a cross-flow filter (2) for oil enrichment upstream of the measuring cell (7, 12) and a compact, pressure-resistant cylindrical ring-type filter (13) made from porous ceramic (16, 16a, 16b) with measuring and flushing connections radially (17a, 17b, 18a, 18b) and axially (17c, 18c).

    摘要: A photoacoustic flow measuring cell (1a, 1b) for measuring oil residues in water including a photoacoustic sensor principle based on converting optical energy into acoustic energy by absorption of light on oil molecules in water. A measuring cell (1a, 1b) having contamination-free infeed optics (9, 10, 11, 21) is produced by providing a free fall stage (3) for a contactless feed (12) of light into an analyte (4). A sound detector (16) is an externally mounted piezoelectric transducer (16) or an optical interferometer (23) which measures vibrations of a liquid surface (6) without contacting the same. The photoacoustic free fall measuring cell (1a, 1b) provides a high level of detection, well into the ppm concentration range, low susceptibility to faults and is suitable, in particular, for use in high pressure separating tanks (28) for conveyance of crude oil.

    摘要: A gas meter for determining a gas mixture consumption is revealed which determines sensor signal values proportional to a flow rate, this gas meter being calibrated as an energy measuring unit. The calibration is based on a basic gas mixture. During the measurement of the gas consumption, a measured energy consumption value is multiplied by a correction factor which takes account, at least approximately, of the calorific value of a supplied gas mixture, this calorific value being determined by an external unit. By this means, it is possible, using a simple and cost-efficient gas meter, to determine the effective supplied energy and to bill costs according to the supply.

    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.
