DEVICE FOR CONTROLLING THE MEASUREMENT OF AT LEAST ONE PARAMETER OF A FLUID UNDER A CERTAIN PRESSURE AND METHOD FOR IMPLEMENTING IT

摘要

The device and the method are characterised in that controllable means 30, 31, 32, 35 allow measurement of the parameter, means 50, 54, etc. allow measurement of the pressure of the fluid and deliver a signal which is a function of a determined pressure variation, this signal then being applied to controllable means for measuring the parameter. Application: in particular, measuring the pressure and/or temperature at the bottom of hydrocarbon extraction wells. IMAGE
