Abstract: A sensor for determining gas content of a two phase fluid flowing in a flow line, the sensor including a sleeve configured to be arranged in the flow line in a stream of fluid. The sleeve includes a plurality of measurement electrodes that, in pairs, define a plurality of subdivision spaces subdividing a flow section of the sleeve. The sensor also includes switch and measurement members coupled to the measurement electrodes to control switching of each subdivision space of the sleeve between a measuring state and a non-measuring state. The switch and measurement members are configured to selectively switch the state of each of the subdivision spaces independently of one another.

Abstract: The present invention relates to a method of thermally and mechanically protecting cables and bundles of cables by use of a sheath braided directly around the element to be protected using a braiding yarn constituted by a plurality of elementary strands formed by interlacing synthetic fibers obtained after cracking and spinning an aramid fiber and a carbonizable oxidized organic fiber. The carbonizable oxidized organic fiber constitutes the major portion of the synthetic fibers making up the elementary strand for the braiding yarn. The invention also provides a thermal and mechanical protective sheath for cables and bundles of cables obtained by the method. In order to improve certain mechanical or thermal characteristics of the sheath, it may be associated with a material made of a fiber additional to said two synthetic fibers, in order to form the elementary strand, or indeed the sheath braided in this way may itself be covered in additional braiding based on aramid fibers.
