GE’s PanaFlow MV82 insertion multivariable mass vortex flow meter is the next generation of vortex meters. PanaFlow MV82’s multivariable design consists of a vortex shedding velocity sensor, an RTD temperature sensor and a solid state pressure transducer that measures the mass flow rate of steam, gases and liquids. Other meter types use external process measurements to calculate mass flow. The temperature and pressure devices are typically not installed in the same location as the flow meter. Process conditions can vary greatly between the two locations, causing inaccurate mass flow readings. PanaFlow MV82 measures velocity, temperature and pressure at the same location, which provides more accurate process measurement.

Features:

  • Multivariable vortex fl owmeter for measuring volumetric fl ow, temperature, pressure, density, and mass fl ow using a single meter
    Advanced design and digital signal processing for vibration isolation
    Cost eff ective, accurate and reliable meter for volumetric and mass fl ow measurement in most gases, liquids and steam without the need to recalibrate
    Energy management through accurate measurement of both temperature and mass fl ow simultaneously
    Remote monitoring and integration to DCS using HART® and Modbus® communication protocols
    Signifi cant cost savings through reduced installation costs, wiring runs and services support using MV meter with no moving parts
    Certified for Division 1/Zone 1 Explosive Atmospheres ?US/CAN/ATEX/IEC Ex
