Designed to be mounted in-line in high-purity applications, these sterile-design visual flow indicators from L.J. Star Inc. provide operators with a clear view of the flow of virtually any process pipeline fluid or fine powder. They feature an internal-flush style that meets FDA and 3-A specifications, based on a unique O-ring seal design that minimizes traps where bacteria can buildup. Polished stainless steel connections include sanitary clamp as standard, with butt weld and flange as special order items. Stop by Booth 747 at INTERPHEX.
