Abstract
An installation () for drilling a well () into a soil comprising: —a discharge pipe () connected to the well () for recovering a drilling mud created by the drilling fluid mixing with components from the soil; —a flow rate sensor () to measure at least one parameter of the recovered drilling mud and generate a parameter value; —a calculator () connected to the flow rate sensor () to receive the parameter value in order to calculate a flow rate of the recovered drilling mud using the parameter value; characterized in that it further comprises a flume () having a throat and an approach channel hydraulically connected to the discharge pipe () to receive the recovered drilling mud, the measured parameter of the recovered drilling mud being representative of a height of the recovered drilling mud in the approach channel.
