Abstract

The pressure meter has a down hole tool (1) e.g. probe, introduced in a boring (F), and a reservoir (4) carried by the down hole tool and containing a liquid (L) and a pressurized gas (G) such as pressurized nitrogen. A gas source (21) delivers the pressurized gas to the reservoir. A volume sensor comprises a liquid level detector (61) housed in the reservoir. A connection unit includes a transmission line (30) connecting the liquid level detector and a surface equipment (2).
