11.5 Signal paths
11.5.1 Measuring sequences
During flow measuring, the meter passes through a number of sequences, repeated at fixed intervals.
Deviations only occur when the meter is in test mode.

between the quantity of water, which has passed through the meter and the measured water flow.
According to metrological and technical requirements/OIML R49, the upper flow limit (Q4/Max flow) is the
highest flow at which the flow meter may operate for short periods, without exceeding maximum permissible
error. The meter has no functional limitations during the period, when the meter operates above this limit
(Q
4
).
Please note, however, that high flow velocities > Q
4
(Max flow) involve the risk of cavitation, especially at low
static pressures below 0.03 MPa (0.3 bar).
