The RotaMass LR (photo) is claimed to be the world’s smallest dual bent-tube Coriolis mass flowmeter. The unit is designed to be self-draining and to measure both liquids and gases, with a mass flow measurement span from 0 to 40 kg/h. The accuracy is ±0.15% for liquids and ±0.5% for gases. This low-flow Coriolis meter is based on a proven dual bent-tube design designed to overcome the shortcomings of single-tube low-flow meters, such as susceptibility to external vibrations and changes in ambient or process fluid temperatures, which lead to less accurate and stable measurements. The RotaMass LR uses an inline temperature sensor, ensuring exact and fast measurements in process temperatures ranging from –50 to 150°C. — Yokogawa Corp. of America, Newnan, Ga.
