Overview

Sierra was the first to introduce multivariable mass vortex flow meters to the market in the late 1990s with the InnovaMass "S-Series" product line--the 240S and 241S. The InnovaMass 240S inline version is a true workhorse in applications ranging from large pipes and ducts, to high pressure and saturated or superheated steam. The InnovaMass 241S is manufactured as a volumetric only version or a multivariable version.

Product Benefits
