Fluid level wake-up functionality

A method, comprising:

• determining, with a low power circuit, that a primary system associated with a storage tank has entered a key-off state;
• based at least in part on determining that the primary system has entered the key-off state, causing, with the low power circuit, a fluid level sensor within the storage tank to determine:
• a first fluid level of a fluid within the storage tank at a first time, and
• a second fluid level of the fluid within the storage tank at a second time;
• determining, with the low power circuit, that a difference between the first fluid level and the second fluid level exceeds a threshold;
• based at least in part on determining that the difference exceeds the threshold, transmitting, with the low power circuit and to a direct power circuit operably connected to a power source, a command causing the direct power circuit to provide power from the power source to a tank controller, wherein the tank controller generates an indication upon receiving the power via the direct power circuit, the indication configured to cause verification of the fluid upon the primary system entering a key-on state;
• and
• based at least in part on the indication, causing the direct power circuit to provide the power to a recording system configured to store the difference and the indication to perform a fluid quality check.

A system, comprising:

• one or more processors;
• and
• a memory storing one or more instructions that are executable by the one or more processors to perform operations comprising:
• determining that a circuit switch has transitioned a primary system from a key-on state to a key-off state;
• providing, from a power source and via a direct power circuit, power to a fluid level sensor associated with a storage tank, the fluid level sensor determining, upon receiving power from the power source,
• a first fluid level of fluid within the storage tank at a first time, and
• a second fluid level of the fluid within the storage tank at a second time different from the first time;
• determining a difference between the first fluid level and the second fluid level;
• determining that the difference exceeds a threshold value;
• and
• based at least in part on determining that the difference exceeds the threshold value, providing, from the power source and via the direct power circuit, power to a recording system operably connected to the one or more processors, the recording system being configured to store an indication that the difference exceeds the threshold value.
