Bronkhorst High-Tech has released a new version of its mini CORI-FLOW Ex d series Coriolis mass flow meter for low flow rates, suitable for use in hazardous areas.
Compact flow meter, operating via the Coriolis principle, are built into a flameproof enclosure with a separated compartment for electronics for added protection and increased safety. In addition to the standard RS232 digital communication, the instruments can also be equipped with a fieldbus interface (Modbus, PROFIBUS DP, DeviceNet, FLOW-BUS) and, on request, an intrinsically safe 4-20 mA output. The instruments also offer additional functions such as alarms, and batch dosing.
The flow meter, 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 138 bar. The unique design of the miniature Coriolis sensor features superior response time and high accuracy, irrespective of changing operating conditions with regard to pressure, temperature, density, conductivity and viscosity.
The Coriolis flow meter offers integrated PID control for close-coupled valves or pumps, thus constituting compact control loops. It also features fluid temperature and density as secondary digital outputs.
The ATEX and IECEx approved instruments find application in process control systems in petro chemical plants and in oil and gas installations.
