The new generation
EL-FLOW® is here

EL-FLOW Prestige is the next generation of Bronkhorst Mass Flow Meters / Controllers for gases. Nearly all core components have been redesigned and many improvements and innovations have been incorporated. With this new series Bronkhorst introduced the “Differential Temperature Balancing” technology, ensuring a superb sensor stability.

Customized Input/Output configurations

Digital pulse output

The programmable pin 5 (9-pin sub-D connector) can be set for a pulse output per quantity, as defined by the user. This pulse can be fed directly to remote totalizing counters, digital readout devices or control instrumentation.

Shut-off valve activation

The digital output of the programmable pin 5 (9-pin sub-D connector) can be used to activate a shut-off valve. For instance, a shut-off valve can be programmed to close when the MFC’s setpoint is zero, to ensure that the gas line is absolutely closed. Alternatively the valve may be activated upon a certain alarm value or when a preset counter value has been reached. This functionality makes the use of valve terminals superfluous.

Shut off valve activation

External reset counter

EL-FLOW Prestige instruments offer alarm and counter functions as a standard feature. To reset the counter value, e.g. locally displayed by a BRIGHT R/C-module, the user should operate the push-buttons. Alternatively, using the digital input option of the programmable pin 5, an external input signal can be sent to the instrument to reset the counter.
