Application need
In environmental monitoring stations, MFCs control the inlet gas blending of analyzers. The equipment is installed in a station room where the ambient temperature changes.
The difficulty
The analyzer needs the amount of gas actually delivered. If temperature or pressure changes and the instrument looks only at its displayed value, the true flow drifts.
What we did
The MFC controls mass (standard-condition) flow with temperature and pressure compensation, so the true flow stays accurate when the temperature changes. The temperature and pressure compensation demo on the home page shows the effect.
Status
Some customers have started using it in equipment, and others have completed tests and met their requirements. This is an area where we have built a foundation and are expanding; please talk to us while the analyzer is being developed.
