Measuring components are either subtractive or consumptive.

According to the Oracle Utilities Customer Cloud Service User Guides, a subtractive measuring component is one that records the cumulative usage of a service point or a device over time1. A consumptive measuring component is one that records the usage of a service point or a device for a specific interval of time2. The difference between these two types of measuring components is how the consumption is calculated. For a subtractive measuring component, the consumption for a given period of time is the end measurement minus the start measurement1. For a consumptive measuring component, the consumption is simply the measurement itself, and represents the consumption for the period of time since the previous measurement was taken2. Subtractive and consumptive measuring components can be associated with any type of service, such as water, gas, or electric, and any type of meter, such as deductive or non-deductive12. References: About Measuring Components, Physical Measuring Components, [Oracle Utilities Customer Cloud Service - Get Started]
