Product Details


Walsn UniMass-V Coriolis flowmeters feature twin shallow-bend V-shaped tubes with a higher working frequency than UniMass-U. The V series provides an optimal combination of performance and compactness. The shallow bend angle provides for excellent drainability when installed vertically or on a small angle. High pressure options are available.

The V 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.
