The MF16 is the micro-flow version of the MF1 metal tube rotameter, made for analyzer systems, purge panels and precision dosing. Actual-flow scales with a 10:1 turndown, an integral needle valve for setting the exact flow, inlet filtration and an outlet check valve protect the float from sticking and clogging.

Three versions cover indication, transmission and alarming: mechanical pointer, LCD two-wire transmitter (4-20mA + HART7) and limit-switch versions with up to two NAMUR switches at class 1.5 accuracy. Wetted parts are 316L and ratings reach PN400 / Class 2500 at -80 C to +200 C.

FAQ

What is the smallest flow the MF16 can measure?

From 1 L/h of water or 30 NL/h of air, with a 10:1 turndown and actual-flow (not converted) scales.

Can the MF16 output a signal or alarm?

Yes. The transmitter version gives two-wire 4-20mA with HART7, and the switch version provides up to two NAMUR limit switches for alarm and control at class 1.5 accuracy.

Where is the MF16 typically used?

Analyzer and sampling systems, gas purge panels, chemical dosing of additives and catalysts, specialty gas monitoring and precise small-flow control in fine chemical and biopharma processes.
