The invention relates to an electrical energy meter comprising a current-measuring circuit and a voltage-measuring circuit, the current-measuring circuit comprising a current sensor producing a first analog measuring voltage and a first analog-to-digital converter arranged so as to carry out a first sampling of the first analog measuring voltage in a such a way as to produce first digital values, and the voltage-measuring circuit comprising a voltage sensor-producing a second analog measuring voltage and a second analog-to-digital converter arranged so as to carry out a second sampling of the second analog measuring voltage in such a way as to produce second digital values, the electrical energy meter also comprising a first synchronization circuit arranged so as to synchronize the frequency of the first sampling and the second sampling.
A method of monitoring a set of meters that are connected to a common remote processor device, the method comprising both first steps performed in each meter for: acquiring primary measurements of a magnitude representative of the occurrence of an anomaly; selecting pertinent measurements from the primary measurements, the pertinent measurements satisfying a pertinence criterion; regularly transmitting the pertinent measurements to the remote processor device; and second steps performed in the remote processor device, for: comparing, for each meter, the pertinent measurements with a detection threshold common to all of the meters of the set of meters in order to attempt detecting an anomaly associated with said meter; and adjusting the detection threshold dynamically as a function of the percentage of meters detected as being associated with an anomaly.

TERMINAL BLOCK HOUSING INTENDED TO RECEIVE AT LEAST ONE MULTI-STRAND CABLE
The invention relates to a housing comprising a terminal block intended to receive at least one end of a multi-strand cable and therefore comprising at least one recess (6a, 6b, 6c, 6d) for receiving the end of the cable, the recess being provided with a wall (8) in which an opening (7a, 7b, 7c, 7d) is arranged and through which the end of the cable extends during use, and a flank (10a, 10b, 10c, 10d) arranged opposite the wall with the opening, at least one surface of the flank facing the inside of the recess being rough in order to limit the risk of at least one strand detached from the end of the cable sliding through a space between the flank and the rest of the housing.
A method of measuring the speed of a fluid, comprising the successive steps of: causing the processor component to emit at the same emission time both a first electrical excitation signal that is applied as input to a first transducer and also a second electrical excitation signal that is applied as input to a second transducer, such that the first transducer generates a first ultrasonic signal and such that the second transducer generates a second ultrasonic signal; putting the processor component on standby; reactivating the processor component after a predetermined standby duration; causing the first ultrasonic signal to be acquired by the second transducer and then by the processor component, and causing the second ultrasonic signal to be acquired by the first transducer and then by the processor component; using a value DToF to estimate the speed of the fluid.
