Yokogawa's RotaMASS 3 Series Adds Modbus Interface

The RotaMASS 3 series extends its communication capabilities with a Modbus interface. Modbus running over RS-485 will be available in with both Modbus RTU and ASCII transmission modes. The fast and simple Modbus communication, running at up 57000 bps, enables access to all relevant process measurements including mass flow, volume flow, density and temperature. All measurement variables are included as readable address registers.

In addition to the other standard field communication protocols such as FOUNDATION™ fieldbus and HART, Modbus offers a Point-to-Point and multi-drop network. The RotaMASS also keeps the standard 4-20 mA, Pulse/Frequency, and Status In/Out as additional options for control or monitoring purposes.

For easy configuration of meter measurements and settings, the free RotaMASS Modbus Communication Tool will be delivered with each RotaMASS. This software is equipped with different functions, clearly displayed in an explorer view. Even with Modbus communication, all settings can be done at the indicator. Simultaneous HART communication via HHT or FDT is also possible.

The RotaMASS is respected in the market for its superior box-in-box design, which decouples the measuring device from external vibrations and stresses for consistent accuracy. With its dual thick walled, u-shaped tubes, it provides an optimum measuring accuracy of +/-0.1% for liquids and +/- 0.5% for gasses. The mass flow measurement range of the RotaMASS spans from 45 kg/h to 600 t/h.
