Abstract: A communications link is evaluated between a communications module connected to a meter and a remote reading terminal. The communications link is established between the meter's communications module and the remote reading terminal under given operating conditions. Then, under substantially the same operating conditions, at least one of the communications parameters of the remote reading terminal is controllable attenuated, and a detection operation is performed to determine whether the communications link between the meter's communications module and the remote reading terminal is still established. Communications parameters of the remote reading terminal that are controllably attenuated, either alone or in combination, include transmitter power and receiver sensitivity.

Abstract: Propagation time Tp of an ultrasound signal between two spaced-apart transducers constituting an emitter and a receiver is measured. The emitter transducer is subjected to an excitation signal of n successive pulses of period Te giving rise to an ultrasound signal being emitted towards the receiver transducer which receives the ultrasound signal generating and outputting a receive signal. A measurement of an intermediate propagation time Tint is started when the emitter transducer begins to be excited. The receive signal is detected and the oscillations in the receive signal are counted. Measurement of the intermediate propagation time Tint is stopped when an ith oscillation is detected. The propagation time Tp is determined by taking the difference Tint?i×Te. Advantageously, measurement of Tint is stopped for an ith oscillation of the receive signal that corresponds to the receive signal being at a maximum amplitude.

Abstract: A method for detecting malfunctions in a flowmeter includes the measuring of the receive signal VIN output by a transducer. A characteristic of the receive signal is compared to a predetermined reference characteristic VREF and the peak voltage VPK of the receive signal is stored. An alarm signal VAL is generated when a trigger characteristic VDEC of the receive signal is less than the predetermined reference characteristic. A threshold voltage VTH is defined, proportional to the peak amplitude VPK of the receive signal in such a manner that VTH=K×VPK where K is a factor depending on the transducer. The receive signal is compared with the threshold voltage and a conditioned output signal VOUT is generated in a first state when the receive signal is greater than the threshold voltage, and in a second state when the receive signal is less than the threshold voltage.

Abstract: The oscillation frequency of a fluid jet in a fluidic oscillator is measured using a temperature sensor. The resistance of the temperature sensor varies as a function of the oscillation of frequency f0 of the jet. The method consists in feeding the temperature sensor with an AC voltage of frequency f, and then in determining the frequency components around the frequency 3×f in the output signal from the temperature sensor in order to determine the oscillation frequency f0 of the jet. The frequency components in the signal output by the temperature sensor are determined by measuring the measurement signal across the terminals of the temperature sensor, then by synchronously demodulating the measurement signal at the frequency 3×f, and finally by determining the frequency of the demodulated measurement signal, which frequency corresponds to the oscillation frequency f0 of the jet.
