# EstimatedVolume

> A volume produced in a period, estimated without a meter (e.g. flow × operating time). Counts only for time no meter interval covers. Since v2.3.

> **EstimatedVolume** = [`ProductionEntryBase`](/core/api/type-aliases/ProductionEntryBase) & `object`

A volume produced in a period, estimated without a meter (e.g. flow ×
operating time). Counts only for time no meter interval covers. Since v2.3.

## Type Declaration

### method?

> `optional` **method?**: [`OpenVocab`](/core/api/type-aliases/OpenVocab)\<[`EstimationMethod`](/core/api/type-aliases/EstimationMethod)\>

Basis of the estimate. Descriptive only: it never changes how the volume
is counted. Recommended values: [ESTIMATION\_METHODS](/core/api/variables/ESTIMATION_METHODS).

### period\_end

> **period\_end**: `string`

RFC 3339 instant the period ends. Later than `period_start`.

### period\_start

> **period\_start**: `string`

RFC 3339 instant the period starts.

### type

> **type**: `"estimated_volume"`

### volume

> **volume**: `number`

Volume in m³.
