Industrial Division, Parker Hannifin:

Manufacturer of Mass Flow Controllers, Flow Meters, Rotameters, and Other Flow Control Products

Welcome to the Industrial Division of Parker Hannifin, a global leader in manufacturing analytical, dental, industrial and medical instrumentation. Since our inception in 1968, the Industrial Division has specialized in the development, manufacture and sale of precision instruments, like mass flow controllers, flow meters, and rotameters, for the measurement and control of gases and liquids. Our 54,000 square foot fully-integrated headquarters and manufacturing facility is located in Hatfield, PA, 35 miles northwest of Philadelphia.

Parker's passion as a precision manufacturer is a legacy dating from our founder's invention of a tube-forming machine utilizing a heat/vacuum process, capable of precisely sizing the internal dimensions and configuration of glass tubing within 50 millionths of an inch. This invention led to the first production of interchangeable, glass rotameter tubes.

Today, in that same tradition of precision, Parker flow and pressure control instruments, both standard or modified to customer design requirements, excel in some of the world's most performance-critical applications. They play a vital role in the production of computer chips. They are trusted for the regulation and measurement of anesthetic gases in operating rooms worldwide. They aid in the production of pharmaceutical drugs, cutting-edge biotech research, dental patient sedation and environmental monitoring.
