Founded in 1946 by Stephen A. Brooks, Brooks Instrument was originally based in Lansdale, Pennsylvania. The company was built on the strength of an innovative side-plate, dowel-pin principle of rotameter construction, which is, today, the basis of one of the companys more important product lines. In 1958 the company developed a new, streamlined laboratory flow meter named Sho-Rate and a new type of full-view rotameter - with an improved packaging seal that represents one of the first innovations for the glass tube rotameter in 20 years.
