Pressure insensitive mass flow controller

The latest from Bronkhorst, providers of flow instruments used for a variety of applications in laboratory, machinery, industrial and hazardous areas

EL-FLOW Prestige, the newest generation of Bronkhorst mass flow meters/controllers for gases, can now be equipped with an onboard pressure sensor.

In combination with differential temperature balancing sensor technology and an incorporated gas database with physical properties, the instrument automatically compensates for inlet pressure variations.

As a result, the accuracy and control stability will not be affected by these pressure changes. Next to an improved yield of the customerís process, additional components for line pressure control will no longer be required.

The multi gas / multi range functionality of the EL-FLOW Prestige enables the user to select any of the installed gases and to adjust the measuring range within the boundaries of the device.

Also the dynamic behaviour of the mass flow controller can easily be tuned onsite, by adjusting the controller speed parameters. These settings can be changed using the software tools FlowTune or FlowPlot.
