Abstract
System for remotely measuring pressure for pressures exerted by a fluid conveyed by a pipe, the system comprising a measuring tube with a first end connected to the pipe and a second end to a pressure sensing element. The measuring tube completely filled with a liquid and comprising watertight membranes that respectively close its both ends retaining the liquid inside it, a first membrane in contact with the fluid and closing its first end, and a second membrane in contact with the pressure sensing element and closing its second end. The first membrane being sensitive to fluid pressure oscillations and the second membrane o liquid pressure oscillations for propagating the pressure exerted by the fluid to the pressure sensing element for its measure.
