The iSeries Vortex Flow Meter for Precise Steam, Liquid, and Gas Flow Measurement

Industrial and manufacturing process control both rely on the highest accuracy steam, liquid, and gas flow measurement possible to optimize productivity, efficiency and cost savings. In the 1990s, Sierra designed and introduced InnovaMass®, the first multivariable mass vortex flow meter in the world. Today, with the latest in firmware advancements, robust software applications, and Sierra's automated state-of-the-art calibration facility, the next generation InnovaMass iSeries—240i (inline) and 241i (insertion)—build on their predecessor's success to drastically exceed their performance. Five...

240i / 241i Highlights • Accuracy of up to 0.7% of reading • Fluids: Mass or volumetric flow metering of gases, liquids and steam • Pipe/duct size: Insertion version: 2 inch (50.8mm) to 72 inches (1.8M) Inline version: 1 inch (DN25) to 8 inches (DN200) • Hot-tap probe retractor • 30:1 turndown • Free user software • Field firmware upgrades • Multivariable: mass flow rate, volumetric flow rate, density, pressure, temperature • Dynamic density calculation improves steam metering accuracy • Flow Energy: steam enthalpy and AGA8 natural gas • In-Situ calibration validation • No moving parts • Raptor...

With all insertion point velocity flow meters, knowing the flow profile is key to stable and reliable accuracy. FloPro improves flow profile knowledge by also calculating the transitional flow regime that occurs between laminar flow and turbulent flow. This all adds up to accuracy you can rely on. WaterLoop World Class Calibration Designed by Sierra and located at our metrology headquarters in Monterey, California, Sierra's Water-Loop™ is among the world's most accurate liquid/gas calibration facilities. Rated at +/- 0.2% of reading, all calibrations follow the guidelines of ISO 17025 and are...

Fluid Measured Mass or volumetric flow measurement of any gas, liquid, or steam Dial-A-Fluid feature to change fluid in the field Fluid Database to build complex fluid mixtures with qMix software Multivariable Outputs Measure five process variables with one process connection: Mass flow rate, volumetric flow rate, density, pressure, and temperature Totalized flow based on user-determined flow units, sixteen full digits Notes: (1) Accuracies stated are for the total mass flow through the pipe. (2) Over 50% to 100% of the pressure transducer's full scale. (3) Nominal rangeability is stated. Precise...

OPERATING SPECIFICATIONS Material Compatibility 240i: Any gas, liquid or steam compatible with 316L stainless steel. Not recommended for multi-phase fluids. 241i: Any gas, liquid or steam compatible with 316L stainless steel. Not recommended for multi-phase fluids. Note: Units with the pressure option use Viton® elastomers. Linear Range Smart electronics corrects for lower flow, down to a Reynolds number of 2,000. The Reynolds number is calculated using the fluid's actual temperature and pressure monitored by the meter. Rangeability depends on the fluid, process connections and pipe size (consult factory...
