The story

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 company's 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.

Products and brands

In 2018, corporate leaders at Brooks introduced a new, annual scholarship program, which awards up to $2,000 per individual to undergraduate engineering students at accredited colleges or universities. The program is designed to support students who show "potential for leadership and interest in engineering, particularly as it relates to instrumentation, fluid mechanics and flow or pressure measurement."
