Sierra InnovaMass® iSeries 240i and 241i Volumetric & Multivariable Mass Vortex Flow Meter

Enquiry Item

The new InnovaMass iSeries vortex flow meter is a game changer in the industrial flow measurement market. The powerful combination of our Raptor II OS, which runs apps like FloPro for real-time flow profile calculation and Dial-A-Fluid, and robust Smart Interface Portal (SIP) software to run field validation & tuning make InnovaMass the most precise and easy to use vortex flow meter on the market.

The onboard Smart Interface Portal (SIP) software allows end-users quick access to filed validation and meter configuration. Access ValidCal Diagnostics through the SIP or meter LCD display to automatically check the meter's firmware and hardware and report faults to the factory for immediate repair. MeterTuning from the SIP or local display allows field adjustments for the low flow cut off and vortex coefficient Ck. Through the SIP, InnovaMass' firmware can also be updated or repaired in-situ (in-the field), saving time and money.


There are many forms of energy contained in flow, whether it is the hear energy (BTU or joules) in steam or water, the potential combustive energy in natural gas, or the potential expansion energy in compressed air. The reinvented InnovaMass 240i and 241i delivers a revolution in flow energy management by maximizing measurement precision and realizes this goal with the new iseries features.  The new InnovaMass 240i/241i iSeries is ideal for saturated or superheated steam, gas and liquid applications and measures mass and/or volumetric flow rate.
