The OPC UA Variable Type MaterialRateType describes a material flow or consumption/production rate. The Value of the Variable represents the quantity of the material flown in 60 seconds, i.e. 1 minute.

Figure 28 shows an overview for the MaterialRateType with related Variable. It is formally defined in Table 76.

The MaterialRateType is formally defined in Table 76.
