Coriolis Flow Meters
QFlow – QMASS 55100 Series
The QFlow QMASS 55100 is a DN100 bent-tube Coriolis flow meter for very high-capacity measurement on large process and transfer lines in oil, gas and chemical industries. A single sensor measures mass flow, density and temperature directly to 260,000 kg/h at ±0.1 % of reading, and 4–20 mA with HART and Modbus RTU outputs serve analogue and digital systems. DN100 flanged connections rated to 40 or 70 bar handle heavy throughput. Within the QMASS family choose this size for duties to 260,000 kg/h; only the DN150 flagship carries more.
