Vortex Volumetric Flow and Multivariable Mass Flow Meters


Vortex is the ideal flow technology for gas, liquid and steam measurement.  Sierra's InnovaMass vortex can be specified to measure up to five process variables with one process connection: volumetric flow, mass flow, density, pressure, and temperature.  With this multivariable capability, it's easier to maximize your steam productivity and reduce cost-of-ownership.

Sierra's next generation InnovaMass "iSeries" (240i inline and 241i insertion) features a new hyper-fast microprocessor, robust software apps, and an automated state-of-the-art manufacturing and flow calibration facility to assure the highest level of quality and delivery.

Reduced Cost of Ownership:  With five high accuracy measurements available from a single compact flowmeter, total cost-of-ownership plummets. Lower initial cost, less complex installation, and reduced maintenance costs contributed to significant overall savings.

Did You Know?  Sierra was the first to design and introduce a multivariable mass vortex flow meter to the world.  Sierra introduced InnovaMass 240S/241S "S-Series" multivariable mass vortex meters to the market in the late 1990s.  Today, multivariable mass vortex units are an industry standard.

The completely re-designed InnovaMass iSeries follows our tradition of innovation forged by products like QuadraTherm 640i and 780i mass flow meters.
