Abstract

To determine the mean density of a fluid flowing along a hyrocarbon well (12), the pressure difference between two regions (H1, B1; H2, B2) situated in the vicinities of the bottom generator line and the top generator line of the well is measured. To this end, a pressure sensor (24, 26) is placed on a tube (28, 30) whose ends open out into the above-mentioned regions, the tube being mounted on an arm (20, 22) that is hinged to the body (14) of the apparatus. The inclination of the straight line joining the two pressure take-off regions (H1, B1; H2, B2) is also determined. The desired mean density is calculated from the measured pressure difference and from the determined inclination.
