Designed to be mounted in‑line for high‑purity hygienic applications, these clamp‑type “CT” sterile‑design visual flow indicators provide operators with a clear view of flow for virtually any process pipeline fluid or powder. They feature an internal‑flush style based on a unique O‑ring seal design that minimizes traps where bacteria can build up. Polished stainless steel sanitary clamp connections are standard, with orbital weld, Swagelok® TS, flange or union connections available as special‑order items.
