2-8 Process Mounting
The Brooks Quantim will function in any orientation if the Coriolis sensor and
the control valve remain filled with process fluid. Entrapped gas in a liquid
application and entrapped liquid in a gas application should be prevented as
it may disturb the Coriolis sensor and the control valve.
Install the Brooks Quantim in the direction of the FLOW arrow.
The arrow indicating proper flow direction is engraved on the front of the
instrument between the process fittings. (See Figure 2-1 below.)
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
