Measured and non-measured meters are terms used in the context of energy measurement and verification. The difference between the two is as follows:
Measured Meters:
Measured meters are devices that directly measure the energy consumption of a particular subsystem or equipment.
They provide accurate and reliable data on energy consumption.
Examples of measured meters include electricity meters, gas meters, and water meters.
Non-measured Meters:
Non-measured meters are devices that estimate the energy consumption of a particular subsystem or equipment based on certain assumptions or calculations.
They provide less accurate and less reliable data on energy consumption compared to measured meters.
Examples of non-measured meters include estimates of energy consumption based on square footage, occupancy, or other factors.
In energy measurement and verification, it is important to use measured meters whenever possible to ensure accurate and reliable data. However, in some cases, measured meters may not be available or feasible, and non-measured meters may need to be used instead. In such cases, it is important to use appropriate assumptions and calculations to estimate energy consumption as accurately as possible.
