When there is entrained air in the process line, an air eliminator should be used.
This entrained air causes air pockets and these air pockets will cause the rotor to
spin at a faster rate than liquid, thus resulting in in- correct readings, which results
in an overstatement of actual flowrate and volume. This condition can damage the
flowmeter.
In process lines where particulates are present, a filter/strainer should be used.
Refer to the table below for the recommended mesh size.

Cleaning Procedures
G-Series Sanitary Turbines are designed to be compatible with commercially
accepted methods of both CIP (Cleaned-In-Place) mechanical cleaning as well as
intermittent SIP (Steam-In-Place) cleaning methods.
If CIP or SIP cleaning methods are not available, manual COP (Cleaning-Out-of-
Place) methods can be used.
Care must be taken during system start-up, chemical cleaning, air purge or steam-
cleaning processes to ensure that the turbine rotor does not over speed as damage
can result to the rotor and/or bearing. Maximum allowable over range for G-Series
Sanitary Turbines is 125% of maximum rated flowrate for intermittent periods.
A minimum fluid velocity of 5 foot per second (1.5 meter per second) must be
maintained during the CIP process to ensure adequate cleaning.

Product and Solution Pipelines and Cleaning Systems Used in
Milk and Milk Product Processing Plants, Number 605-XX as
amended for procedures and recommended flowrates.
The following flowrates are recommended by the 3-A Recommended Practices
