Gas flow meters

Ultrasonic gas flow meter for upstream applications

Your Benefits

  • Low initial investment – precise measurement without an expensive high-pressure flow calibration
  • Low subsequent investments – no costly measurement station upgrades or orifice plate changeovers thanks to the wide measuring range
  • Lower operating costs – long maintenance-free operation, and servicing only when required as indicated by remote diagnostics
  • High reliability thanks to real time monitoring of all device diagnostics data
  • Extended process monitoring with unique wet gas detection feature
  • Better measurement accuracy than orifice measurements under wet gas conditions
  • Long service life thanks to the moisture- and contamination-resistant encapsulated ultrasonic sensors

Ultrasonic gas flow meter for upstream applications

The innovative FLOWSIC600 DRU gas flow meter for upstream applications based on the FLOWSIC600. With a measuring range of up to 150:11, the FLOWSIC600 DRU also covers flow ranges that previously required several orifice plates. Low manufacturing tolerances and wet-gas tolerant ultrasonic sensors ensure consistently low measurement uncertainty, even under challenging conditions. SICK therefore makes it possible to skip the otherwise common cost-intensive high-pressure flow calibration. The FLOWSIC600 DRU enables real-time diagnostics of devices and processes and is virtually maintenance-free - even with high liquid loads.

1 Increasing measurement uncertainty at flow speeds of less than 0.9 m/s.
