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

Constants

Назва	Тип	Значення	Опис
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).
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).
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).
