mini CORI-FLOW M15 Coriolis Mass Flow Meters/Controllers - 1

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. TM mini CORI-FLOWTM 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. TM Fields of application 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.

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 p ­ erformance 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 meas­ ring principle offers the following advantages: u • no conversion factors (if scaled in units of weight) •...

Mass Flow Controller Close-coupled control valves Mass flow control with pumps For control applications M15 mini CORI-FLOW meters offer integrated, adaptable PID control for fast and smooth control of close-coupled control valves. This could be a standard direct acting, electro magnetic control valve or, for instance, a pilot operated valve for applications with high differential pressure. TM Close-coupled control valve options: M15+C0I: Gas flow control valve (nc), Kv-max= 6,6x10-2 M15+C2I: Liquid flow control valve (nc), Kv-max= 2,3x10-3 M15+C5I: Gas/Liquid flow control valve (nc),...
