Bronkhorst 布琅轲锶特 Model M12 质量流量计和控制器

General","mini CORI-FLOW™ series by Bronkhorst are precise and compact Mass Flow Meters and Controllers, based on the Coriolis measuring principle. Designed to cover the needs of the low flow market, there are 4 models to overlap flow ranges from 5 g\/h up to 300 kg\/h (full scale values), each offering scalable range functionality: factory calibrated ranges can be rescaled by the user, maintaining the original accuracy specs. The instruments are equipped with a robust IP65 weatherproof housing.","Superior Coriolis flow sensor","Instruments of the mini CORI-FLOW™ series contain 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. Coriolis mass flow measurement is fast, accurate and inherently bi-directional. The mini CORI-FLOW™ features density and temperature of the fluid as secondary outputs.","Fields of application","mini CORI-FLOW™ instruments can be applied for both gases and liquids in process fluid measurement or control systems in semiconductor processing, in fuel cell technology, in food, (petro-) chemical and pharmaceutical industries or analytical installations (e.g. GC, HPLC or SFC systems measuring \/ dosing supercritical CO2) and in liquid dosing systems for micro reactors, amongst many others.","Features
