Bronkhorst mini CORI-FLOW mass flow meters and controllers

Click2Contact

The mini CORI-FLOW series by Bronkhorst are compact mass flow meters and controllers based on the Coriolis measuring principle. Designed to cover the needs of the low-flow market, there are three models to overlap flow ranges from 5 g/h up to 30 kg/h (full scale values), each offering multi-range functionality. Factory-calibrated ranges can be rescaled by the user, maintaining the original accuracy specifications. As a result, users 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.

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 meters also feature density and temperature of the fluid as secondary outputs. Coriolis flow meters are offer high accuracy and when applied for liquids, the mass flow accuracy is better than ±0.2% Rd.

The mini CORI-FLOW meters can be applied to the mass flow measurement of most liquid types. They are fully metal-sealed, and the controllers have a high-performance elastomeric valve seat made of Kalrez.
