    • Disclosed are an apparatus for and a method of automatically digitizing an indication value of a meter. A light emitter emits a light towards the outer circumferential face of a target number wheel of which rotation numbers are to be counted. A light receiver receives and converts the reflected light into an optical detection signal. The optical detection signal is converted into a digital data, which is provided to a metering computer unit. A determination result as to whether the supplied goods are currently being consumed is provided to the metering computer unit. The metering computer unit counts an increase by T only if the stabilized state is caused by use of the supplied goods. Further, a temperature and pressure compensation unit is further adopted, which compensates for the meter reading errors caused by a difference between reference temperature and pressure at the gas-supplying point and the temperature and pressure values of the gas passing through the gas meter, i.e., calculates a temperature and pressure compensation coefficient. The metering computer unit reflects this compensation coefficient on the automatic read value to provide a more precise digitalized read value.

    • The invention relates to an energy-saving sampling method and an electrical apparatus (1, 1'), particularly an electronic gas meter (1') or motion detector (1), for carrying out said method. The aim of the invention is to reduce power consumption (I) of the battery (105) in said method and apparatus (1, 1'). Said aim is achieved by sampling the test signal (100b, 101b) in a quasi continuous (13) manner by defining sampling time slots (14') during which sampling is done in an uninterrupted fashion while sampling gaps (14) during which no sampling is done are allowed between the sampling time slots (14'). Examples of embodiments include sampling gaps (14) at regular or random intervals, sampling gaps (14) with a variable duration and/or frequency and especially an increasing duration and/or frequency as the remaining service life of the battery decreases, and a lower sampling rate (f1, f2, f3) during the sampling time slots (14'), among others, resulting in an increased battery lifetime without substantially reducing test reliability.

    • A vortex flow transmitter (10) has a filtering circuit (20) receiving a noise contaminated input signal representative of the flow and which has a fundamental frequency varying responsively to flow. The filter (20) filters the input signal using one of a family of HP filter characteristics. Each member of the family of HP filters has varying corner frequencies, each filter having a unique switchup and a unique switchdown value assigned to it. Adaptive response means (40) select a current HP filter for use in the filter means. The adaptive means use one selection method when the flow is increasing and another selection method when the flow decreases. Output means (52) convert the signal from the filter means into a transmitter output, typically a 4-20 mA current or a frequency output representative of the flow.
