Features of Metal Tube Rotameter

Multiple wetted material options

Wetted parts can be configured in 304, 316L stainless steel, PTFE or titanium alloy. This flexibility allows the meter to cope with weak‑acid, alkaline and other corrosive liquid and gas media on site.

Flexible multi‑direction installation

Available in vertical, horizontal, bottom‑in side‑out and side‑in side‑out configurations. Various connection types including flange, internal thread and sanitary clamp suit diverse field piping requirements.

Magnetic non‑contact transmission

Float displacement is transferred via magnetic coupling with no direct mechanical linkage. It reduces internal wear, lowers failure risk and extends instrument service lifetime under continuous operation.

Optional alarm function

Upper‑limit and lower‑limit flow alarm switches are selectable. Relay signals can trigger interlock actions, helping operators respond promptly to abnormal liquid or gas flow conditions.

Wide measuring scope for small flow

Well‑suited for low‑flow liquid and gas measurement. Its 10:1 standard rangeability covers common process conditions without demanding long upstream and downstream straight pipe runs.
