Bronkhorst FLEXI-FLOW mass flow meter and controller

Click2Contact

The FLEXI-FLOW mass flow meter and controller from Bronkhorst combines the advantages of a through-chip-sensor with bypass technology. The company says the compact thermal mass flow meters and controllers are 35% smaller than traditional instruments, and offer flow ranges up to 20 ln/min.

Due to the sensing technique, the instruments feature stable but fast flow control, with settling times smaller than 150 ms.

FLEXI-FLOW instruments have integrated temperature and pressure sensors and an onboard gas database for high accuracy, even in varying process conditions. With this technology, the instruments 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.

For easy set-up and monitoring of the instruments and the process, Bronkhorst has introduced a USB-C port, optional Bluetooth communication and NAMUR status indication by means of coloured LEDs and digital output parameters. FLEXI-FLOW is available in two preconfigured models, as a built-to-order version or as a customised, multi-channel solution, each including software tools for configuration, diagnostics and predictive maintenance.
