摘要： The invention relates to a method for the highly accurate digital measurement of an analogue signal and to a corresponding device. A measuring clock pulse (fM) is generated from a clock pulse signal (fT). In a first calibration step, a capacitor (C) is charged with a constant current (IK) during the entire period of the clock pulse signal (fT). The charge voltage is maintained and is converted into a digital comparison number. In a subsequent measuring step, a first portion (T1) of the duration of the analogue signal is determined as an appropriately selected, whole-numbered multiple (m) of the duration (T0) of the period of the clock pulse signal (fT). The capacitor (C) is charged with the same constant current (IK) from the end of the first portion (T1) until the occurrence on the specified flank of the received signal (fE). The charge voltage is maintained and converted into a digital measuring number. The measuring number is divided by the comparison number, which permits the duration of a second portion (T2) of the analogue signal to be calculated as a fraction of a measuring clock pulse period. The measured value of the analogue signal is calculated from the first portion (T1) and the second portion (T2).

摘要： The subject matter of the invention is an annular piston counter for consumption measurement of fluids with less noise being developed. This is achieved by the size of a first gap (y) between the piston pin (32) and the dome (11), a second gap (x) between the piston casing (31) and the housing casing (10), and a third gap (e) between the piston casing (31) and the dome (11), such that the piston casing (31) does not touch either the dome (11) or the measurement chamber casing (10) during the oscillating movement of the annular piston (30).

摘要： A worm gear unit is disclosed for roller type counters to be used in highly sensitive and accurate supply meters. The worm gear unit comprises a screw (10) and a worm wheel (20) with teeth (21) that mesh with the screw (10). The worm wheel (20) forms at the same time the first number roller of the roller type counter. In order to reduce friction, the teeth (21) are provided only on the flank (22) which extends parallel to the flank (12) of the screw thread (11) and meshes with the screw (10) during the forward movement of the supply meter.

摘要： The invention relates to a converter for an ultrasound flowmeter. In said converters, a converter element (2) is arranged in a converter housing (1), comprising a front electrode (21) on the side facing the medium and an opposing rear electrode (22), which are mounted on a ceramic disc. According to the invention, an elastic rubber moulded seal (6) surrounds the body surface of the converter element (2) and the external parts of the front and rear side thereof. A better electroacoustic efficiency is achieved by means of the direct contact of the front electrode (21) with the medium. The front electrode (21), facing the medium, is advantageously provided with protective layer, for example made from titanium nitride. Said converters can be used in ultrasound flowmeters for both liquid and gaseous media.

摘要： The invention relates to water meters to be mounted in pipe conduits of a nominal diameter class and to a method for operating such water meters that function according to the Woltmann principle. The aim of the invention is to provide a device and a method which eliminates the need for calibration of every nominal diameter of the nominal diameter class, thereby avoiding the corresponding disadvantages. To this end, the water meters have, in the relevant location, namely in the annular channel (16) directly upstream of the impeller wheel (8), independent of the nominal diameter of the pipe conduit connected, a substantially rectangular speed distribution (19) with flow threads that are substantially parallel to the wall of the annular channel (16), said flow conditions being substantially identical at identical flow rates.

摘要： A method and apparatus for coupling a meter register to a communication device such that output data signals from the meter register can be transmitted to a remote location. The coupling arrangement includes a data transfer wire that is connected to the meter register and is inductively coupled to the communication device such that the data transfer wire does not need to be conductively connected to the communication device. During installation of the communication device, the inductive coupling between the data transfer wire and the communication device eliminates the requirement of a conductive connection.

摘要： A system for providing the ability to obtain consumption data from a communication device used to transmit accumulated data from the meter register. The system includes a programming port formed as part of the communication device. The programming port includes the programming coil that allows the accumulation data received from the meter register to be read by an interrogation device. Further, the programming coil allows programming information to be transferred to the communication device from the interrogation device. The system can also include a reading module coupled to the programming port of the communication device through an inductive coupling. The reading module can extend through a pit lid such that the reading module can be accessed without removing the pit lid.
