Abstract: A mechanical fluid meter, for liquid or gas, includes an electronic device (E) that has means for metering, and generally also displaying, consumption, said fluid meter including: at least one fluid temperature sensor (3) near the meter and at least one ambient temperature sensor (4) where the meter is installed; a connection means between the temperature sensors (3, 4) and the electronic device (E); and analysis means (5) for establishing the temperature difference (??) between the fluid temperature and the ambient temperature and for taking into account the fluid flow rate value supplied by the meter, said analysis means being programmed so as to display and/or transmit information indicating a meter blockage when the temperature difference (??) is higher than a predetermined limit and the flow rate value supplied by the meter is zero.

Abstract: System for transmitting data for remote logging between a measurement sensor (1a, 1b) comprising an electronic circuit with non-synchronized internal clock and a memory for storing at least one value measured at a first instant (t1), and a transmitter (7) suitable for transmitting at a second instant (t2) the value or values measured at the first instant (t1), and a receiver (12, 12a) synchronized to a reference time base, for gathering the measured values transmitted; the sensor (1a, 1b) comprising an electronic circuit suitable for establishing the time difference ?t (t2?t1) between the instants of transmission (t2) and of measurement (t1) according to the internal clock of the sensor, and the transmitter (7) transmits, with the value or values measured at the first instant (t1), this time difference ?t; and the receiver comprises a circuit for subtracting from the reception instant (T0) according to the reference time base, the time difference (?t) transmitted via the transmitter so as to give the differen

Abstract: Method for inspecting, in real time, the quality of water of a drinking water delivery network comprising, on the one hand, on connections for consumers, consumption meters (9a) fitted with remote-reading devices, and, on the other hand, on-line analysers (10a) distributed at supervision points on the network in order to measure at least one parameter of water quality. The meters (9a) are fitted with remote-reading devices and the consumption data of the various meters (9a), and the measurements of the analysers (10a) are transmitted to a programmed computing unit (A) with a kinetic model of decrease of the quality parameter in question; the computing unit (A) permanently updates the hydraulic model according to the consumption data received from the meters (9a, 9b etc.

Abstract: The present invention relates to a remote water-meter reading device (8) that comprises an assembly (10) for acquiring consumption data and comprising at least one radio transmitter for transmitting the information acquired, at least one radio receiver incorporated into the acquisition assembly (10) so as to enable said device (1) to communicate in both directions in order to receive the information from a central unit (2), and an antenna (11) so that said central unit can transmit time/date information such that this transmission of information taken into account by said radio receivers makes it possible to guarantee exact timing/dating of all the acquisition assemblies (10) of the meters that form one and the same lot, characterized in that said meter (8) initiates a volume-consumed measurement at a time determined by a first timing/dating received from the central unit (2) by the receiver and stops it at a time determined by a second timing/dating received from the central unit (2) by the receiver, the vol

Abstract: Device (D) for producing energy, from solar radiation (RS), intended for a building or industrial construction (1), comprising, on the outside, at least one first wall (2) made up of translucent photovoltaic panels (4) and towards the inside some distance away from the first wall, a dark-coloured opaque second wall (3) positioned facing the first wall (2), a gap (5) being created between the first (2) and the second (3) wall, the energy being produced in electrical form by the photovoltaic panels (4) and in thermal form by the second wall (3) which recovers, in the form of hot air or hot water, some of the radiation that has passed through the first wall (2).

Abstract: The invention relates to a method for processing nitrogen-concentrated effluents by ammonia oxidation into nitrites followed by nitrite denitritation in a gaseous nitrogen in a sequential biological reactor (1) consisting in pouring a processable effluent volume in to the reactor by successive volume fractions, in dividing the entire processing cycle into successive sub cycles, wherein each sub-cycle comprises a feeding phase, an aeration phase for nitrification and an anoxia phase along which a carbon-containing source is introduced into the reactor for converting nitrites into nitrogen.

Abstract: A denitrification reactor with a culture fixed to an organized plastic-type support is combined with an installation for the nitrification and elimination of the carbon-based pollution The reactor is supplied with a mixture of the raw effluent to be treated and of the effluent originating from the installation for the nitrification and elimination of the carbon-based pollution. The reactor includes two denitrification compartments (3, 4) arranged in parallel and operating altenatingly between a filling phase (denitrification and self cleaning-out of the excess biomass); and an emptying phase (denitrification and drainage of the excess biomass). A system for supplying the mixture of effluents consisting of a rotary arm (11) which alternately supplies the mixture to each of the compartments.
