摘要： A measurer for measuring a flow rate of a medium which may be multi-component or heterogeneous, independently of the medium, a signal-generating unit generating a transmit signal on the basis of a reference signal of a signal generator and transmitting same by means of a stimulator via the flowing medium. This signal is received by a sensor and passed on to an evaluating unit which is implemented to determine a signal transfer time based on a plurality of mutually corresponding locations of a waveform of the receive signal and the waveform corresponding to the reference signal and the flow rate of the medium based on the signal transfer time and the certain distance between the stimulator and the sensor.

摘要： A frequency generator according to the invention includes a controllable oscillator comprising a control input and an oscillator output, wherein the controllable oscillator is formed to output, at the oscillator output, an oscillator signal with an oscillator frequency dependent on a control signal at the control input, sampling means for sampling the oscillator signal or a signal of the controllable oscillator derived therefrom with a reference frequency, in order to obtain a sample signal, and a low-pass filter for low-pass filtering the sample signal or a signal derived therefrom, in order to obtain the control signal or a signal underlying the control signal. Due to the less intensive construction, in particular the lack of a frequency divider, and the quicker adjustability of the currently generated frequency, according to the invention, more current-saving frequency generation may be obtained.

摘要： The present invention relates to a transponder reading device for reading out a plurality of inductive passive transponders having a resonant circuit. A transmitter is provided to create an alternating magnetic field having an operating frequency fB, in which the number of transponders may be placed such that same are magnetically coupled to each other. A retuning means is further provided which is arranged in the alternating magnetic field and has such a frequency-dependent impedance that a voltage induced in the resonant circuits of the transponders by the alternating magnetic field has a maximum in the range of the operating frequency fB.
