Bronkhorst Cori-Tech B.V. achieved a technological breakthrough in Coriolis mass flow measurement and control, by realising the mini CORI-FLOW series, compact and cost-effective Coriolis Mass Flow Meters/Controllers for accurate measurement and control of (very) low flow rates; from 100 mg/h up to 30 kg/h. 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 2000:1, with easy, on-site possibility for the user to re-range the instrument to his requirements, thus guaranteeing highest process flexibility.

Suitable for both liquid and gas flow applications and capable of bi-directional measurement, the instruments are equipped with robust IP65 weatherproof housing and available with approval for use in hazardous areas (ATEX Cat.3 Zone 2). Mini CORI-FLOW offers 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. The instruments feature fluid temperature and density as secondary digital outputs.

Typical applications include research laboratories, pilot plant, semiconductor and fuel cell processing, food and pharmaceutical industries, analytical installations, micro-reactors, surface technology and anywhere requiring direct mass flow measurement, independent of fluid properties.
