OPTIMASS 1010 Coriolis Mass Flowmeter

Source: KROHNE, Inc.

The OPTIMASS 1010 is a cost-effective twin straight tube Coriolis mass flowmeter for a wide range of universal and hygienic applications with liquids and gases (up to 170,000 kg/h or 6,235 lb/min and +130°C / +266°F). It features an integrated Modbus converter. This makes the flowmeter an ideal solution 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 1010 features an optimised flow splitter for minimum pressure loss and can be drained and cleaned easily. Next to standard flange process connections, the flowmeter supports a wide range of standard hygienic connections for food and beverage applications. It is also suitable for use in hazardous areas. The OPTIMASS 1010 is 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.
