Bronkhorst FLEXI-FLOW multifunctional mass flow meters/controllers

Click2Contact

Bronkhorst’s FLEXI-FLOW compact thermal mass flow meters/controllers, for flow ranges up to 20 ln/min, are designed to be 35% smaller than traditional instruments. Combining the advantages of a through-chip sensor with bypass technology, the instruments feature stable flow control but also fast control, with settling times smaller than 150 ms.

The instruments have integrated temperature and pressure sensors and an onboard gas database to enable high accuracy, even at varying process conditions. They are adaptable to many applications through their wide dynamic flow ranges (up to 1:1000). The temperature and pressure signals may provide the user with information about the actual process conditions. The product is therefore more than just a flow meter or controller — it is a multiparameter measurement/control device.

The unit is available in two preconfigured models, as a built-to-order version or as a customised, multichannel solution, each including free and easy software tools for configuration, diagnostics and predictive maintenance. For easy set-up and monitoring of the instruments and the user’s process, Bronkhorst introduces a USB-C port, optional Bluetooth communication and NAMUR status indication by means of coloured LEDs and digital output parameters.
