Flowmeters for Sanitary and Ultrapure Applications

Sanitary applications such as food processing and ultrapure applications such as semiconductor processing often require precise flow control and an unobstructed flow path. Finding the right flow meter or flow switch for these applications can be daunting.

Depending on the process, these applications can range in size from 1/4" connections to 6" and may utilize either Tri-Clamp, VCR, VCO, or stub-weld process connections. Many sanitary installations require "CIP/SIP" (clean in place) design, and for ultrapure designs a 10-15 RA finish may be required. The body of the flow switch should be all welded to minimize any area for contamination to hide and prevent leakage. And since many ultrapure fluids can be highly corrosive, a body made of 316 stainless steel (low sulfur) is typical but other corrosion resistant materials such as Hastelloy C,  Monel, Inconel, Tantalum, and Carpenter 20 may be required.
