New Mini Coriolis Flow Meters for Smallest Flow Rates  

Bronkhorst Cori-Tech (The Netherlands) has released a new model in its series of compact Coriolis Mass Flow Meters/Controllers for accurate measurement and control of (very) low flow rates. With the mini CORI-FLOW® model M12 the lowest capacity has been reduced to 0,4…20 g/h. The instruments are suitable for both measurement and control for liquid flow as well as gas flow applications. 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 effective turndown is no less than 1000:1, with easy, on-site possibility for the user to re-range the instrument to his requirements, thus guaranteeing highest process flexibility.

Mini CORI-FLOW®, being the smallest Corilios flow meters on the market, have a robust IP65 weatherproof housing and are available with approval for use in hazardous areas (ATEX Cat.3 Zone 2). The instruments offer integrated PID control and close-coupled control valves or pumps, thus constituting very compact Coriolis mass flow control loops.

Mini CORI-FLOW® features state-of-the-art digital technology, offering standard analogue and RS-232 communication, optional fieldbus interfaces and additional functions such as alarms, totaliser (to measure fluid consumption) and batch dosing. Both fluid temperature and density are available as secondary digital outputs.

Typical applications include research laboratories, food and pharmaceutical industries, analytical installations, micro-reactors and anywhere requiring accurate, fluid independent mass flow measurement or dosage of very small flow rates.
