However, if the rate rises again above the Sand Alarm Level
within the Time to alarm reset period, the accumulator continues
to accumulate the sand production. When the accumulated sand
production exceeds the Sand Alarm Mass, a Sand Alarm is
generated. (See Figure 5-1). This alarm will be reset when the rate
drops below the Sand Alarm Level minus Alarm Bound Limit for
a time period longer than the Time to alarm reset. This will be
directly affected by the values which are entered in Sand Mass
Accumulation.

5.1.3 Sand rate alarm
It is recommended that this is either set to the same value as sand
rate threshold for sand mass accumulation, or a lower rate. When the
sand rate exceeds the value, an alarm is triggered.
Default value: 1.000 g/s
