Abstract

The disclosed technology concerns a method for providing a liquid solution from a liquid solution tank at a target pressure to an injector fluidically connected to a pump via a supply line, the pump being fluidically connected to the liquid solution tank, comprising the steps of:- Running (110) the pump at a first predefined speed;- After a first duration, measuring (120) the pressure of the liquid solution in the supply line;- If the measured pressure is lower than a threshold pressure lower than the target pressure, running (140) the pump at a second predefined speed lower than the first predefined speed;- If the measured pressure is greater than or equal to the threshold pressure, measuring (150) the pressure of the liquid solution in the supply line after a second duration;- If the measured pressure after the second duration is lower than the target pressure, stop (170) running the pump.
