OPTIMASS 7010 Coriolis Mass Flowmeter

Source: KROHNE, Inc.

The OPTIMASS 7010 is a high-end single straight tube Coriolis mass flowmeter. It is particularly suitable for demanding process and dosing applications involving gases and shear-sensitive or viscous liquids, slurries, very aggressive media or media with a low flow velocity. The Coriolis meter features an integrated Modbus converter. This makes it the ideal solution for applications where a DCS or a PLC is already in use and extensive communication options and control functions are not necessary. By way of its Modbus interface the flowmeter integrates easily into existing controller systems. There is no need for a conventional signal converter. Purchase costs can be saved.

The OPTIMASS 7010 is available in four sensor materials (titanium, stainless steel, Hastelloy®, tantalum). Due to its sensor design, there is virtually no pressure loss and the flowmeter is self-draining and easy to clean, which makes it also the perfect choice for hygienic applications. The Coriolis device is also approved for use in hazardous areas. It is additionally available with an EtherNet/IPTM Interface Box offering a full-featured web-interface for configuration, maintenance and diagnostics as well as smooth integration into major EtherNet/IPTM host systems.
