Abstract
Method and apparatus to monitor the quantity of magnetically permeable particles in admixture with a fluid carrier in which the mixture is placed in a magnetic field having flux lines which change in direction or position. The mixture is out of physical contact with a source of the field and with a movable member the degree of movement of which is influenced by the strength of the field. The degree of movement of the member is monitored and this corresponds to the quantity of particles in the mixture.
