Steady Flow Meter

The SFM300 steady flow meter is a flow meter with a built-in (Built-in type) flow straightening function to counter the effects of turbulent flow (turbulent flow) during measurement, designed to prevent measurement error.
The SFM305 is a model that combines a flow straightener (commutator) and a flow element in a single insertion-type (Insertion type) product for large-bore ducts and pipes, providing stable measurement while reducing cost.
Both models have a turndown of 6:1, and the material is selected from Carbon Steel, STS304, STS316, Inconel, Monel and Hastelloy.
SFM300 — Shank due to turbulent flow on measuring, Built-in type for measuring error-prevention. SFM305 — In large duct or pipe case, Insertion type product containing a commutator and flow element for Saving cost and stable measuring. Turndown Range 6:1, Accuracy ±2.0%.
