APPLICATION
DATA SHEET 90222
In
very low flow applications, two Micro Flowmeters may be required to attain
the desired accuracy or repeatability. This is especially true when the
liquid to be measured is low in lubricity. In such cases, an installation
such as depicted in the drawing below is recommended. If, for example,
it is required to flow distilled water at 2 ccpm, the system may be set
to pump at 25 ccpm through Micro Flowmeter 1, and the Control Valve adjusted
so as to cause 23 ccpm through Micro Flowmeter 2 which returns this amount
to the Liquid Sump.
