# FuelTankStatus (UORB message)
|
|
|
|
**TOPICS:** fuel_tank_status
|
|
|
|
## Fields
|
|
|
|
| Назва | Тип | Unit [Frame] | Range/Enum | Опис |
|
|
| --------------------------------------------------------------- | --------- | ---------------------------------------------------------------- | ---------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
|
|
| timestamp | `uint64` | | | time since system start (microseconds) |
|
|
| maximum_fuel_capacity | `float32` | | | maximum fuel capacity. Must always be provided, either from the driver or a parameter |
|
|
| consumed_fuel | `float32` | | | consumed fuel, NaN if not measured. Should not be inferred from the max fuel capacity |
|
|
| fuel_consumption_rate | `float32` | | | fuel consumption rate, NaN if not measured |
|
|
| percent_remaining | `uint8` | | | percentage of remaining fuel, UINT8_MAX if not provided |
|
|
| remaining_fuel | `float32` | | | remaining fuel, NaN if not measured. Should not be inferred from the max fuel capacity |
|
|
| fuel_tank_id | `uint8` | | | identifier for the fuel tank. Must match ID of other messages for same fuel system. 0 by default when only a single tank exists |
|
|
| fuel_type | `uint32` | | | type of fuel based on MAV_FUEL_TYPE enum. Set to MAV_FUEL_TYPE_UNKNOWN if unknown or it does not fit the provided types |
|
|
| temperature | `float32` | | | fuel temperature in Kelvin, NaN if not measured |
|

|
|
| <a id="#MAV_FUEL_TYPE_UNKNOWN"></a> MAV_FUEL_TYPE_UNKNOWN | `uint8` | 0 | fuel type not specified. Fuel levels are normalized (i.e., maximum is 1, and other levels are relative to 1). |
|
|
| <a id="#MAV_FUEL_TYPE_LIQUID"></a> MAV_FUEL_TYPE_LIQUID | `uint8` | 1 | represents generic liquid fuels, such as gasoline or diesel. Fuel levels are measured in millilitres (ml), and flow rates in millilitres per second (ml/s). |
|
|
| <a id="#MAV_FUEL_TYPE_GAS"></a> MAV_FUEL_TYPE_GAS | `uint8` | 2 | represents a gas fuel, such as hydrogen, methane, or propane. Fuel levels are in kilo-Pascal (kPa), and flow rates are in milliliters per second (ml/s). |
