The RotaMASS LR dual bent tube Coriolis mass flowmeter employs a proven dual-bent-tube design and represents a significant advance to Yokogawa’s RotaMASS Low Flow Line product family for gas and liquid flow measurement. Designed to be self-draining and to measure both liquids and gases, the mass flow measurement spans from 0-40 kg/h. The accuracy is +/- 0.15% for liquids and +/- 0.5% for gases. The RotaMASS LR meets the market’s demand for accurate and stable measurement of fluids at low flow rates. Yokogawa developed the low flow Coriolis meter based on its proven dual bent tube design to overcome the current shortcomings of single tube low flow meters, including susceptibility to external vibrations and changes in ambient or process fluid temperatures, which lead to less accurate and stable measurements in real-world conditions.
