Horizontal Mounting
If installing the Brooks Quantim in a horizontal orientation, liquids should
flow in the direction of the flow arrow. Situations of entrapped gas in the
liquid process should be avoided. In liquid flow applications, it is
recommended to mount the Quantim in an inverted attitude on the underside
of the pipe to limit the possibilitiy of entrapped gas collecting in the sensor,
which can cause errors (See Figure 2-2).
For use in gas flow measurement, the Quantim should be mounted on the
topside of the pipe to limit the possibility of entrapped fluid collecting in the
sensor, which can cause errors. (See Figure 2-3).
