Abstract: A wireless pressure sensor of a swimming pool filtration system includes a pressure switch, a communication unit, an energy storage element, a memory for recording multiple consecutive measurements, and an analysis device. The analysis device is configured to detect a critical situation if one or more current measurements exceed a critical value and/or if the pressure difference between a current measurement and the last measurement recorded in the memory is greater than a predetermined value. The communication unit is configured to send, upon expiration of a transmission period, the measurements stored in said memory. The communication unit also is configured to transmit the measurements stored in the memory before the expiration of the transmission period when the analysis device detects a critical situation.

Abstract: The present invention relates to a filtration unit for filtering the water in a pool or basin, in particular a swimming pool, said unit being mounted behind a wall of said pool, and communicating with said pool via a suction intake (3, 6) and via a delivery orifice to generate a forced flow of water from and back into the pool through a filtration tank and through a suction column by means of centrifugal hydraulic pump. The centrifugal hydraulic pump has an electric motor coupled to a centrifugal turbine housed in a pump body. The electric motor is a sealed, brushless, autonomously controlled motor that is powered at very low voltage and that may advantageously be immersed inside the filtration unit below the level of the water contained in said pool, thereby enabling said motor to be cooled and sound-proofed naturally by the forced flow of the water from the pool, thereby forming a filtration unit and a pool that have low energy consumption.

Abstract: A modular and multipurpose covering device for a pool includes a first modular covering tarpaulin forming a tailor-made safety cover made up of first tarpaulin elements which are joined together reversibly by transverse supports. A second modular covering tarpaulin is superimposed with the first tarpaulin and made up of second tarpaulin elements which are joined together reversibly by the same transverse supports. This second covering tarpaulin affords additional functions that can be modified according to the season. The two end transverse supports are coupled to lashing and tensioning mechanism for securing and holding down on ground covering device that is arranged over a pool.
