If a flow of more than 133% the nominal maximum flow rate of the Mass Flow
Meter is taking place (displayed mass flow reading is flashing), a condition
known as "swamping" may occur. Readings of a "swamped" meter cannot be
assumed to be either accurate or linear. Flow must be restored to below 133%
of maximum meter range. Once flow rates are lowered to within calibrated
range, the swamping condition will end.
