This group of validation rules checks that the values in the time series do not exceed maximum rates of change. When the rate of change limit is exceeded, the values causing the limit to be exceeded will be marked as unreliable. Rate of change limits may be defined to be the same for the rate of rise as for the rate of fall. These may also be defined to be different. The rates need to be specified in the unit of the timeseries it applies per second. E.g. if you define a rate of change for a water level gauge with values in metres the rate should be given in metres per second.

- constantValue: Maximum rate of rise, used irrespective of date of the value. unitofinput/s
rateOfFall
Validation rule defined for the rate of fall.

- constantValue: Maximum rate of fall, used irrespective of date of the value. unitofinput/s
monthLimit
Element used when defining variable limits per calendar month. Twelve values must be defined. When defined the monthly limit will overrule the constant limit.
