We describe a low cost optical fibre sensor devoted to the continuous characterization of the density of drilling muds used in oil prospecting. It is constituted by two parallel edge to edge fibres. flee of them permits to light the particles spread in the mud while the other acts at the same time to collect a part of the back-scattered light and to carry back it to a photodetector. With such a device, for the muds used in this field and containing a very high number of particles by unit of volume, the response is always a decreasing function of the density.
