    Abstract: The invention relates to a gas meter, especially for household and industrial use, comprising a CMOS anemometer (2) which is provided as a means for determining a consumed quantity of gas, which measures a change in temperature of a gas flowing through or over said anemometer and, as a result, determines the flow rate of the gas. In addition, a density sensor (3) is preferably provided which serves as a means for correcting measured values generated by the anemometer (2).

    Abstract: A capacitative level sensor (1), especially for determining the boundary (34) between water (3) and oil (4) in a separator tank (2), comprises a measurement probe (5) with an electrode (6). The probe has an electrically insulating cover (7), and at least one outer layer (7a) made of fluorated plastic and at least one inner layer (7b) made of a plastic containing mica.

    Abstract: The coverings have differing thicknesses (di, dj). Measurements of capacity between electrodes (4, 5, 6, 13) are used to calculate the effective thickness (ds/ epsilon s) of an insulating film of contamination (14). An Independent claim is included for a capacitative level sensor. Preferred Features: The quotient of double layer capacities CDSj and CDSi for the ith and jth electrodes is obtained from a cited equation. The effective thickness is obtained from a further equation, relating dielectric constant of the coverings, their thicknesses, and capacitor areas. The sensor has a covering thickness of ca. 1 mm, with a dielectric constant below 5. The contaminant film electrical characteristics are specified in terms of a critical frequency related to measurement. Measurement frequency is specified as a function of dielectric relaxation frequency at the boundary layer. Though dielectric thickness varies and the electrodes are segmented, the probe external configuration, is a long, smooth, cylindrical rod.

    Abstract: The movement sensor and actuator system has a current supply unit comprising solar cells (7) and an energy store (6) connected to the cells. The actuator controls a light or lamp (5) which radiates at least some light onto the solar cells. An energy store monitor (8) determines the current charge state of the energy store. The monitor sends a signal to switch the light on when the charge state of the energy store falls below a minimum value, without movement needing to be sensed.
