Coriolis Flow Meters
QFlow – QMASS 5580 Series
The QFlow QMASS 5580 is a DN80 bent-tube Coriolis flow meter for high-capacity measurement on large process lines in oil, gas and chemical plant. A single sensor measures mass flow, density and temperature directly to 180,000 kg/h at ±0.1 % of reading, and 4–20 mA with HART and Modbus RTU outputs integrate with analogue loops and digital networks. DN80 flanged connections rated to 40 or 100 bar suit heavy process throughput. Within the QMASS family choose this size for duties to 180,000 kg/h; sister sizes run from 360 to 480,000 kg/h.
