UniMass-U

Overview

Walsn UniMass-U Coriolis flowmeters use an enhanced classic U or Ω -shape with a patented balancing structure. Featuring the highest sensitivity, the U series provides high accuracy measurement, a higher turn-down and a wide selection of sizes. A lower drive frequency enables the U series to tackle difficult multiphase conditions and a single bent tube design covers low flow rate measurements.

The U series connects to the wide range of UniMass flow converters permitting online system configuration, diagnostics and data recording, providing not only mass flow rate, but also simultaneously measures density, temperature, volumetric flow rate, total flow and concentrations.
