Sierra Instruments InnovaMass 240i and 241i vortex mass flow meters

The Sierra Instruments InnovaMass 240i and 241i vortex mass flow meters have been specifically designed for precise flow energy management in steam, compressed air, natural gas and water applications. Capable of measuring five process variables with one instrument, the flow meters now feature the Raptor II operating system, claimed to provide end users with flow measurement precision that promises to reduce energy costs and increase productivity.

Forms of energy in flow include heat energy (BTU or Joules) in steam or water, the potential combustive energy in natural gas and the potential expansion energy in compressed air. The InnovaMass 240i and 241i mass flow meters deliver flow energy calculations (AGA8 natural gas, steam enthalpy, thermal energy/BTU).

The FloPro software application improves point-velocity accuracy for the insertion version. In addition, the Raptor II OS Flow Engine and MassBalance sensor technology extends the measuring range down to Reynolds numbers well below 5000.

The flow meters are suitable for saturated or superheated steam, gas and liquid applications and measure mass and/or volumetric flow rate. The insertion version is for 50.8 mm or greater, while inline models support up to DN 200. Accuracy is up to 0.7% of reading, temperature to 200°C and pressure to 1500 psig (103 barg). They also offer three configurable 4–20 mA outputs, as well as HART, Modbus, Profibus DP, Foundation Fieldbus, USB and RS-232, as well as CE, cFMus, ATEX and IECEx approvals.
