FLOWSIC600 DRU Ultrasonic gas flow meter for upstream applications



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.
