OPTIMASS 3010 Coriolis Mass Flowmeter

Source: KROHNE, Inc.

The OPTIMASS 3010 is a cost-effective Coriolis mass flowmeter for low flow and dosing applications with liquids and gases (from 0.3 kg/h or 0.01 lb/min upwards). The flowmeter 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 3010 features a single Z-tube design which guarantees a low pressure drop across the meter. It is available with NPT connections, a range of flange connections as well as standard hygienic connections. The Coriolis device can also be used 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.
