## Abstract

A system comprising a plurality of ports is capable of automated, remote detection of conditions indicating that refill is required in one of a plurality of remote tanks and causing refill of the tank via at least one of the plurality of ports. Further, the system includes automated monitoring and supply of a fuel tank.

## Claims

### Claim 1

A multi-port remote filling system, the system comprising:
a supply tank mounted on a trailer;
at least one reservoir, each said reservoir fluidly associated with a stationary engine;
each said reservoir comprising a tank interface assembly each said assembly fluidly associated with the supply tank;
each said at least one tank interface assembly associated with a fluid level sensor configured to detect a level of fluid in the reservoir, the fluid level sensor comprising a float and a sender, wherein the sender is operatively connected to the float, and said sender comprises a relative vertical position, said position changing with the depth of the fluid in the reservoir, wherein when the float lowers the sender to the bottom of the reservoir, the sender opens a solenoid valve in the tank interface assembly controlling the flow of the fluid from the supply tank thereby refilling the reservoir, and when the float is adequately buoyed by the fluid in the reservoir, the sender closes the solenoid valve.

### Claim 2 (depends on 1)

The system of claim 1, wherein at least one of the tank interface assemblies further comprises a manual switch, at least one quick coupler, and a fluid fill connection.

### Claim 3 (depends on 2)

The system of claim 2, wherein the supply tank provides any one of diesel exhaust fluid, gas, natural gas, propane, hydrogen, or bio-fuel.

### Claim 4 (depends on 2)

The system of claim 2, further comprising:
an auxiliary heater to supply heat to fluid in the supply tank to maintain operable temperature of the fluid in the supply tank without means to supply heat to said more than one reservoirs.

### Claim 5 (depends on 2)

The system of claim 2, further comprising:
a manifold, said manifold fluidly associated with the supply tank for the purpose of fluid distribution to each of said more than one reservoir.

### Claim 6 (depends on 5)

The system of claim 5, wherein at least the supply tank and the manifold are mounted on a wheeled trailer.

### Claim 7 (depends on 6)

The system of claim 6, further comprising:
a utility box, wherein the utility box comprises said manifold, a power supply cord, a power supply cord reel, a conduit, a conduit reel, and a fluid pump.

### Claim 8 (depends on 7)

The system of claim 7, wherein the supply tank provides one of diesel exhaust fluid, gas, natural gas, propane, hydrogen, or bio-fuel.

### Claim 9 (depends on 1)

The system of claim 1, further comprising:
a computing device, wherein the fluid level sensor is associated with said computing device.

### Claim 10 (depends on 9)

The system of claim 9, wherein said computing device comprises a processor and memory.

### Claim 11 (depends on 1)

The system of claim 1, further comprising:
a utility box, wherein the utility box comprises a first multi-port manifold and a second four-port manifold in series with the first multi-port manifold, a power supply cord, a power supply cord reel, a conduit, a conduit reel, a plurality of quick couplers for transfer of fluid from the supply tank to any one or more reservoir, and a pump, wherein at least the utility box is mounted on a wheeled trailer.

### Claim 12 (depends on 1)

The system of claim 1, wherein a conduit fluidly connects the supply tank to a quick coupler associated with the tank interface assembly.

### Claim 13 (depends on 1)

The system of claim 1, wherein the supply tank provides one of diesel exhaust fluid, gas, natural gas, propane, hydrogen, or bio-fuel.

### Claim 14 (depends on 1)

The system of claim 1, wherein the system further comprises:
an adaptive routine for tracking historical data regarding fluid flow, wherein the system further comprises a processor, a computing device, software, and a user interface for automating the adaptive routine.

### Claim 15 (depends on 1)

The system of claim 1, further comprising:
a manifold, wherein each of said tank interface assemblies is associated with the supply tank by said manifold.

### Claim 16 (depends on 1)

The system of claim 1, wherein a first conduit fluidly connects the supply tank to a quick coupler of the tank interface assembly; wherein a second conduit fluidly connects the tank interface assembly to the tank.
