Coriolis Flow Meters
QFlow – QMASS 55150 Series
The QFlow QMASS 55150 is a DN150 bent-tube Coriolis flow meter for very high-capacity mass flow measurement on the largest process and transfer lines in oil, gas and chemical plant. A single sensor measures mass flow, density and temperature directly up to 480,000 kg/h at ±0.1 % of reading, and 4–20 mA with HART and Modbus RTU outputs integrate with analogue and digital control. DN150 flanged connections rated to 40 or 70 bar handle maximum throughput. This is the largest QMASS size, for duties to 480,000 kg/h; smaller sister sizes start at 360 kg/h.
