FLEXIM - FLUXUS HPI - Hydrocarbon Media Detection and Mass - Hydrocarbon Media Detection and Flow Measurement

Hydrocarbon Media Detection and Flow Measurement

Non-invasive Hydrocarbon Media Detection and Mass Flow Metering

By combining the attributes of FLEXIM’s highly accurate and reliable non-invasive ultrasonic flow measurement with temperature and, where necessary, pressure inputs, the integrated FLUXUS HPI flow meter is the ideal solution for hydrocarbon flow metering and media detection / identifcation applications, where the fluid viscosity can significantly vary over the temperature range.

The FLUXUS HPI flow meter allows to report:

  • Operational and standard (net) volume and mass flow
  • Density, API number and Specific Gravity
  • Sonic ID (for Interface Detection)
  • Liquid ID (for Fluid Identification)
  • Leak detection (data source based on multiple HPI flow meters)

FLEXIM’s FLUXUS HPI flow meter eliminates measurement errors associated with multiple devices at various places and provides a complete turn-key solution to your flow metering needs.
