Compact Coriolis Mass Flow Meters & Controllers for Liquids and Gases General Coriolis mass flow meters are highly appreciated for their accuracy and independence of fluid properties. The direct Coriolis mass flow measuring principle is generally used for higher flow rates. However, Bronkhorst® has succeeded in applying this technique for low to very low flows. Moreover, mini CORI-FLOW” instruments have an integrated PID-controller and a batch counter to control the fluid flow. mini CORI-FLOW™ model M15 In addition to the previously developed mini CORI-FLOW” series M12-M14 for ranges from 0,1 g/h up to 30 kg/h, Bronkhorst® developed the new model M15 for mass flow rates between 0,2 and 300 kg/h. Similar to the models for lower flow rates, M15 contains a uniquely shaped, single loop sensor tube, forming part of an oscillating system. When a fluid flows through the tube, Coriolis forces cause a variable phase shift, which is detected by sensors and fed into the integrally mounted pc-board. The resulting output signal is strictly proportional to the real mass flow rate. All instruments of the mini CORI-FLOW” series feature density and temperature of the fluid as secondary outputs. Furthermore the instruments offer "scalable range" functionality: factory calibrated ranges can be rescaled by the user, maintaining the original accuracy specs. As a result of this, customers are able to reduce the variety of instruments and thus reduce the cost of ownership. The instruments are equipped with a robust IP65 weatherproof housing and are available with optional ATEX approval for use in Zone 2 hazardous areas. mini CORI-FLOW” instruments can be applied for both gases and liquids in process fluid measurement or control systems in (petro-) chemical and pharmaceutical industries, food & beverage applications and liquid dosing systems in a wide variety of markets. mini CORI-FLOW™ Ml5 Mass Flow Meter > direct flow measurement, independent of fluid properties > integrated PID controller for control valve or pump > CORI-FILLTM or FLUIFILL batch dosing functionality > fast response time > high accuracy, excellent repeatability > additional density and temperature outputs > compact design (same footprint as CORI-FLOWTM M50 series) > excellent price/performance ratio > scalable range: easy on site re-ranging via digital interface (large rangeability) > no dead volume (single, uninterrupted tube) > insensitive for environment vibrations > analog I/O-signals, RS232-connection, optional on-board fieldbus interface > IP65 design, optional ATEX approval Cat.3, Zone 2

Mass Flow Meter Capacities Application on liquids mini CORI-FLOW can be applied for most liquid types. The mass flow meters are fully metal sealed, controllers have a high performance elastomeric valve seat, made of Kalrez. TM smallest range nominal range highest range* * Maximum capacities depend on the available pressure difference across the mass flow meter, especially when used on gases. Application on gases In comparison with thermal mass flow devices, the Coriolis measuring principle offers the following advantages: • no conversion factors (if scaled in units of weight) • possibility to...
