Meter

A Meter is an identifier for recording meter readings, measurements and observations on assets or locations.

Once defined, a meter is added to an asset or location. There are three meter types.

Continuous meters are associated with meter readings where the value increases over time unless it reaches a point at which the meter rolls over and returns to zero. For example, the odometer in a vehicle. There would be an associated unit of measure, miles or kilometres. You will need to decide whether the meter readings will default to actual values or a delta value, the difference between the last and current meter reading.

Gauge meters are associated with measurements where the value can fluctuate over time, for example temperature or pressure. A unit of measure will also be required.

Characteristic meters are associated with observations, the acceptable values are defined by a domain, which must be defined first. A unit of measure is not used with a characteristic meter.

The Meters application is used for creating meters of each type. The identifier, is called the meter name. You cannot create a location meter or asset meter until the meter name has been defined. These meter references are defined at the System level.
