Bronkhorst Cori-Tech B.V. of Ruurlo, The Netherlands has launched a new model in its series of compact Coriolis mass flow meters/controllers (MFCs) for accurate measurement and control of (very) low flow rates.
With the introduction of mini CORI-FLOW model M15, the maximum flow range of the product line is extended from 0-30kg/h to 0-300kg/h. The instruments are suitable for both liquid and gas flow applications.
The firm claims that 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 1500:1, with the possibility for the user to easily re-range the instrument to their requirements on-site, guaranteeing the highest process flexibility, it is claimed.
The instruments have a robust IP65 weatherproof housing and are designed to withstand an operating pressure of up to 100 bar. Mini CORI-FLOW also offers integrated PID control and close-coupled control valves or pumps, constituting very compact Coriolis mass flow control loops.
The Mini CORI-FLOW features digital technology, offering standard analog and RS232 communication, optional fieldbus interfaces and additional functions such as alarms, totalizer (to measure fluid consumption) and batch dosing. The instruments also feature fluid temperature and density as secondary digital outputs.
