Product Information

In 1997, Sierra was the first to introduce a combination volumetric vortex and multivariable mass flow meter. Today, Sierra’s completely redesigned InnovaMass® iSeries™ 240i/241i builds on two decades of success measuring five process variables for gas, liquid, and steam with one connection.

With this multivariable capability, it's easier to maximize your steam productivity and reduce overall cost of ownership for more energy savings.

It Has Apps.  Now You Have The Power.

Experience innovative tools driven by our new Raptor II OS that will empower you and save time and money.

  • ValidCal Diagnistics™ delivers field validation
  • MeterTuning ™ cancels noise, improves accuracy
  • Dial-A-Pipe™ allows you to quickly change pipe sizes in the field
  • Dial-A-Fluid™ measures a variety of fluids whenever you choose
  • qMix ™ makes/measures custom mixtures
  • Many more apps to come

Boiler MACT Certified

The InnovaMass vortex is also ideal for compliance for Boiler MACT regulations for steam outlet and inlet feed water measurements for area source boilers (40 CFR 63, subpart JJJJJJ) and for major source boilers (40 CFR 63, subpart DDDDD).
