Yokogawa released the Rotamess XR Coriolis mass flowmeter, which is the largest ever product of its type and is capable of handling a maximum flow rate of 600 t/h. It offers state-of-the-art accuracy – 0.1 % of measured value for liquids and 0.5 % of measured value for gases – as well as good zero and long-term stability. Featuring the box in box design with dual balanced metering tubes, the measuring device is based on a self-draining design and can carry out bi-directional measurements on mass flow, density and temperature, as well as derive the values of concentration, volume flow, and net flow. In common with the rest of the Rotamass 3 series, the model XR offers a temperature measurement accuracy of 0.5 °C. Rotamass XR will operate over a temperature range of -200 to 230 °C, and is suitable for use in high solid content slurry applications when used with the high-power option. Built-in self-diagnostic capabilities including slug flow detection and compensation as well as corrosion detection are standard features. In addition to digital communication via Hart or Foundation fieldbus, Atex, IECEx, and FM approval options are available for use in hazardous environments. With the multi-flange concept offering process connections up to 8“ ASME class 300 and DN 200, PN 40 as standard, the model XR is suitable for the most demanding applications.
