Coriolis Mass Flow Meter

Now available with IECEx and ATEX approval II 2G Ex d IIB T6 for use in hazardous areas, the mini CORI-FLOW series compact mass flow meters from Bronkhorst Cori-Tech are suitable for both liquid and gas flow applications, covering rates ranging from 0.1 g/h to 30 kg/h. Operating via the Coriolis principle, they are built into a rugged enclosure with separated compartment for electronics. The flow meters can be used in systems with pipeline pressures up to 140 bar. The miniature Coriolis sensor features quick response time and high accuracy, irrespective of changing operating conditions with regard to pressure, temperature, density, conductivity and viscosity. The mass flow meters offer integrated PID control for close-coupled control valves or pumps, thus constituting compact Coriolis mass flow control loops. They offer both analogue and RS-232 communication, optional fieldbus interfaces and additional functions such as alarms, totalizer (to measure fluid consumption) and batch dosing. Fluid temperature and density are featured as secondary digital outputs. As an option, the flow meter can be equipped with a heater to prevent condensation or solidification inside the instrument. Applications can be found in process control systems as for example in food, chemical and petrochemical plants.
