    摘要: A method monitors an operation of a fluid meter mounted in a fluid-supplying fluid distribution system. Wherein, by use of an ultrasonic transducer, an event, in the form of a noise generated during the operation of the fluid meter or a pressure surge generated in the distribution system, which is not attributable to the flow measurement and which mechanically excites the ultrasonic transducer, is selectively detected and evaluated and, by reference to a result of the evaluation, at least one fluid meter-specific operating property is generated.

    摘要: A pulse generator has a galvanically isolated output, in particular for a consumption meter. A control output of a control unit of the pulse generator is coupled to an input of an opto-isolator of the pulse generator in order to output at the output of the opto-isolator an output current controlled by the control unit. The opto-isolator is connected to a field-effect transistor in such a way that the output current from the opto-isolator charges a capacitor via a rectifying component, which blocks the capacitor from discharging via the opto-isolator. The voltage drop across the capacitor is the gate voltage of the field-effect transistor. The field-effect transistor switches the output of the pulse generator directly or indirectly.

    摘要: A measurement module determines a fluid quantity which relates to a property of a fluid located in or flowing through a measurement tube. The measurement module contains a base body, a control device and first and second oscillation transducers fastened at a distance from one another on the base body. The first and/or the second oscillation transducer is controlled by the control device to excite an oscillation of a side wall of the measurement tube when a contact face of the measurement module is coupled to the side wall of the measurement tube directly or via a coupling layer. The oscillation of the side wall excites compression oscillations of the fluid, which are conducted through the fluid to the respective other oscillation transducer and recorded the control device to determine a measurement quantity. The fluid quantity can be determined by the control device in dependence on the measurement quantity.

    摘要: A measuring device for determining a fluid variable relating to a fluid or fluid flow includes a control device, a measuring tube receiving the fluid or fluid flow, and oscillation transducers spaced apart on the measuring tube. At least one oscillation transducer is drivable by the control device to excite a wave conducted through at least one side wall of the measuring tube, the conducted wave exciting compression oscillations of the fluid conducted through the fluid to the other oscillation transducer and recorded there by the control device to determine measurement data. The fluid variable can be determined by the control device as a function of the measurement data. At least one further side wall of the measuring tube has at least one recess extending in a flow direction and increasing a flow cross section of the measuring tube. A method for determining a fluid variable is also provided.

    摘要: A flow meter detects a flow rate of a fluid. The flow meter includes a housing having a flow passage, through which the fluid can be guided from an inlet opening of the housing to an outlet opening of the housing, a measuring tube, which is inserted into the flow passage and constricts the flow cross section in one section of the flow passage, and a holding device, by which the measuring tube is retained on the housing. A respective flow straightener having at least one aperture through which the fluid can flow is arranged between the inlet opening and the measuring tube and/or between the measuring tube and the outlet opening. The flow straightener is configured as a separate component part, which is secured on the holding device by a form-locking or force-locking connection.

    摘要: An ultrasonic meter for recording a flow quantity dependent on a flow of a fluid, has a control device, a measuring tube having a plurality of side walls, mutually adjacent side walls being at an angle to one another, and through which the fluid can flow in a longitudinal direction of the measuring tube, and first and second ultrasound transducers which are arranged at a distance from one another in the longitudinal direction on the measuring tube. The first and second ultrasound transducers respectively contain one transducer element or a predetermined arrangement of a plurality of transducer elements. The ultrasound transducer can be driven by the control device in order to excite an acoustic wave conducted in a side wall of the measuring tube, and conducted through the fluid to the other ultrasound transducer and recorded there by the control device to determine a signal time of flight.

    摘要: A method for determining measurement information includes conducting waves excited by first oscillation transducers to second oscillation transducers or back to the first transducers and recording to determine measurement data. The measurement information is determined using first and second data or first data determine an excitation parameter of a second wave. The first transducers excite the second wave with polarities reversed relative to a polarity for excitation of a first wave, or subgroups of the first transducers operate differently to excite the first and second waves, and/or first and second subgroups of the first or second transducers are used for recording. Only measurement signals of the first subgroup are used, or measurement signals of first and second subgroups are added to record the first data. Only measurement signals of the second subgroup are used, or measurement signals of subgroups are subtracted, or vice versa, to record second data.
