Flow Meter Measurements
The ow meter measures ow through the system
being leak-tested. This is normal while the system
is being lled. If ow meter indicates ow after the
system is lled, this indicates a leak. The higher the
ball is in the ow meter, the larger the leak size. No
ow indicates no ow through the system, or no leak.
The position of the ball indicates the size of the leak.
Note: For accurate .010"/.020"/.040" measurements,
the ow control valve must be in the fully open
position.
