Abstract (en)
[origin: FR2895011A1] The pressure meter has a reservoir (4) carried by a down hole tool (1) e.g. probe, and a pressurized gas whose flow is controlled by a nozzle (221) and a valve (222). A pressure control unit includes a computer (8) and a control unit (7) for selectively opening the valve for application of new pressure set points (Kpi) conforming to an application program (PROG) during time intervals (Tpi) corresponding to the set points.
