Designed for in‑line mounting in high‑purity hygienic processes, these sterile‑design visual flow indicators give operators a clear, unobstructed view of virtually any process pipeline fluid or powder flow. Their internal‑flush configuration, combined with a unique O‑ring seal design, minimises dead legs where bacteria can accumulate.
