Transducer mounting assembly

A transducer mounting assembly for use in conjunction with apparatus for measuring the percentage of said particles in a suspension flowing through a pipe comprising:

• a first semicircular collar member;
• a radiant energy source mounted on said first collar member and adapted to radiate energy toward the interior of the circle defined by said first collar;
• a back-scattered radiant energy detector mounted on said first collar member and adapted to detect energy returning from the interior of the circle defined by said first collar member;
• a second semicircular collar member;
• a forward-scattered radiant energy detector mounted on said second collar member and adapted to detect energy returning from the interior of the circle defined by said second collar member;
• hinge means coupling one end of said first collar member to one end of said second collar member for providing an articulating assembly adapted to be removably mounted around a section of pipe;
• and
• means for detachably securing the other ends of said first and second collar members together when said articulating assembly is positioned around a section of pipe.
