Bronkhorst Cori-Tech mini Cori-Flow Coriolis mass flow meter for low flows

Bronkhorst Cori-Tech of The Netherlands has released an option for its mini Cori-Flow series mass flow meters for low flow rates. The compact flow meters, operating via the Coriolis principle, are now available with IECEx and ATEX approval II 2G Ex d IIB T6 for use in hazardous areas.

The instrument is built into a rugged enclosure with separated compartment for the electronics. The flow meters, suitable for both liquid and gas flow applications, cover flow rates from 0.1 g/h to 30 kg/h and can be used in systems with pipeline pressures up to 140 bar (2000 psi). The design of the miniature Coriolis sensor features short response time and high accuracy, irrespective of changing operating conditions with regard to pressure, temperature, density, conductivity and viscosity.

Mini Cori-Flow mass flow meters offer integrated PID control for close-coupled control valves or pumps, thus constituting compact Coriolis mass flow control loops. The instruments offer both analog and RS232 communication, optional fieldbus interfaces and additional functions such as alarms, totaliser (to measure fluid consumption) and batch dosing. The mass flow meters feature fluid temperature and density as secondary digital outputs. As an option, the Coriolis flow meter can be equipped with a heater to prevent condensation or solidification inside the instrument.

Applications can be found in process control systems in food, chemical and petrochemical plants.
