Embodiment Construction

[0069] In order to simplify future descriptions, the same reference numerals are used for the same elements or elements performing the same function in various implementation modes of the present invention.

[0070] The present invention relates to an autonomous device for measuring at least one property of a fluid circulating in a pipeline and possibly changing one or more of its properties. The device is energy autonomous, as such, it includes a generator that converts the kinetic energy of the fluid into electrical charge. The working principle of the generator is described below.

[0071] dynamo

[0072] Such as Figure 1c As shown in the example in , a generator 1 operated by the invention comprises a magneto-electric converter 2 and a magnetic field source 3 such as a permanent magnet. Converter 2 and source 3 are movable relative to each other. As detailed later in this statement, the generator may remain stationary and the source 3 may rotate under the action of ...

Abstract

The invention relates to an autonomous device (10) for measuring at least one characteristic of a fluid circulating in a conduit in a flow direction. The device comprises a permanent magnetic field source; a magneto-electric converter (2) and a processing circuit (12a) capable of using the electric charges supplied by the converter to supply a measurement of a characteristic of its environment. The source and the converter are placed in a stator (12) and a rotor (11) forming the device. The autonomous device further comprises attachment means (13) allowing the stator (12) to be fixedly placedin the conduit (14) or at one end of the conduit (14), in a configuration in which the axis of rotation of the rotor (11) is parallel to the flow direction. The invention further relates to a controlsystem employing at least one such autonomous device (10).

Description

technical field [0001] The present invention relates to an autonomous device for measuring the properties of fluids circulating in ducts, and in particular the flow properties of air circulating in ventilation, air conditioning or heating ducts of buildings. The invention also relates to a system for controlling the ventilation, air conditioning and / or heating of buildings using this device. Background technique [0002] Modern buildings are equipped with ventilation, air conditioning and / or heating systems that allow the renewal of indoor air and expel stale air. This prevents excess harmful compounds or particles (CO 2 , volatile organic compounds, etc.) accumulation. Excessive humidity, which can cause damage to the building, is also avoided and a satisfactory level of comfort is provided for the residents. [0003] As far as ventilation is concerned, and generally, known solutions consist in drawing room air from the most humid possible rooms (shower room, kitchen) th...
