Coriolis Flow Meters
QFlow – QMASS 5515 Series
The QFlow QMASS 5515 is a versatile DN15 bent-tube Coriolis mass flow meter for process dosing and small production lines in oil, gas and chemical industries. Its bent-tube sensor measures mass flow directly across 0 to 3000 kg/h with accuracy from ±0.1 % of reading, and 4–20 mA with HART and Modbus RTU outputs serve both analogue loops and digital networks. DN15 process connections make it an adaptable choice for everyday process metering and batching. Within the QMASS family choose this size for duties to 3,000 kg/h; sister sizes run from 360 to 480,000 kg/h.
