Abstract

This invention relates to a system for measuring solid particles, e.g. sand, in a fluid flow in a pipe, comprising at least one acoustic sensor for registering acoustic signals generated from collisions between particles and a surface. The pipe comprises a constriction through which the fluid flow passes, and that at least one of said acoustic sensors are positioned in relation to said constriction, and on a surface facing toward the flow so as to receive acoustic signals resulting from collisions between particles and the surface.
