The devices of the BOREAS series are flow transmitters based on the calorimetric (thermal) principle in the splash-proof IP65 housing.
This robust design makes the devices very insensitive and allows very accurate measuring results even in rough environments.

The devices use state-of-the-art microprocessor technology for linearization of the measurement curve as well as temperature-compensated sensors, thus achieving the extremely high precision that these devices have.

The standard, internal USB interface allows bidirectional communication to configure the devices, as well as digital, serial output of the measured value with free software under various operating systems and is optionally available as an external, IP65-protected version.
The devices can be tared at the push of a button, using software or via an externally connected button.

They also have an adjustable 9-stage damping for calming the measurement signal in case of unsteady or pulsating flow. The attenuation is adjusted by means of buttons or software.

High-quality 16-bit digital-to-analog converters are used for the output of the analog signals, enabling precise, low-noise current or voltage signals.

The devices are calibrated according to DIN1343 with air (0 ° C and 1013mbar), but a total of six different gas standards can be selected via software.

The BOREAS housing can be opened without screws, thanks to the innovative hinge-closing technology, and a variant that can be opened without tools is also available as an option.

Various analog output signals, an optional illuminated LCD display as well as a measuring range between 10 mln / min and 3000 mln / min make the BOREAS an all-rounder among flow transmitters.
