Pressure insensitive mass flow controller

10 September 2018

EL-FLOW Prestige, the latest generation of Bronkhorst mass flow meters/controllers for gases, can now be equipped with an on-board pressure sensor. In combination with its ‘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 is not affected by these pressure changes. Next to an improved yield of the customer’s process, additional components for line pressure control will no longer be required.

The multi gas/multi range functionality of the EL-FLOW Prestige enables users to select any of the installed gases and to adjust the measuring range within the boundaries of the device. The dynamic behaviour of the controller can be tuned on site by adjusting the controller speed parameters. These settings can be changed using our free software tools FlowTune or FlowPlot.
