System for remotely measuring pressure for pressures exerted by a fluid (2) conveyed by a pipe (1), the system comprising a measuring tube (3) with a first end (4) connected to the pipe (1) and a second end (5) to a pressure sensing element (6). The measuring tube (3) completely filled with a liquid (7) and comprising watertight membranes that respectively close its both ends (4, 5) retaining the liquid (7) inside it, a first membrane (8) in contact with the fluid (2) and closing its first end (4), and a second membrane (9) in contact with the pressure sensing element (6) and closing its second end (5). The first membrane (8) being sensitive to fluid (2) pressure oscillations and the second membrane (9) to liquid (7) pressure oscillations for propagating the pressure exerted by the fluid (2) to the pressure sensing element (6) for its measure. |
