Coriolis Flow Meters
QFlow – QMASS 5506 Series
The QFlow QMASS 5506 is a compact DN6 bent-tube Coriolis mass flow meter for precision dosing, injection and skid applications in oil, gas and chemical processes. The bent-tube sensor measures mass flow directly across 0 to 1200 kg/h with accuracy from ±0.1 % of reading, and 4–20 mA with HART and Modbus RTU outputs integrate it into analogue loops and digital control. Flanged process connections rated to 40 or 100 bar suit packaged skid and injection systems. Within the QMASS family choose this size for duties to 1,200 kg/h; sister sizes run from 360 to 480,000 kg/h.
