Abstract
A method and apparatus for detecting and measuring gelled material (i.e. gelled pig) as it passes through a tubular by generating ultrasonic pulses at timed intervals which, in turn, are transmitted through said tubular and materials flowing therethrough at a fixed point along said tubular. These pulses are received after they have passed through said tubular and the materials and are processed to identify those pulses which travel through said gelled material as said gelled material passes by said fixed point. From the number of identified pulses, the length of the gelled pig can be determined.
