Fuel delivery system and method
A fuel delivery system and method for reducing the likelihood that a fuel tank of equipment at a well site during fracturing of a well will run out of fuel. A fuel source has plural fuel outlets, a hose on each fuel outlet of the plural fuel outlets, each hose being connected to a fuel cap on a respective one of the fuel tanks for delivery of fuel to the fuel tank. At least a manually controlled valve at each fuel outlet controls fluid flow through the hose at the respective fuel outlet.
1. A cap for a fuel tank of equipment at a well site during fracturing of a well, comprising:
a housing having a throat and a top end;
a first port in the top end provided with a connection for securing a hose to the cap;
a second port in the top end holding a fuel level sensor, the fuel level sensor detecting low and high fuel levels in the fuel tank; and
an air vent for exhausting air from the fuel tank to atmosphere during delivery of fuel to the fuel tank.
2. The cap of claim 1 in which the first port comprises an overfill prevention valve.
3. The cap of claim 1 in which the cap comprises a wireless transceiver connected to the fuel level sensor for communicating signals from the fuel level sensor to a remote controller.
4. The cap of claim 1 in which the air vent comprises slots.
5. The cap of claim 1 in which the housing further comprises a releasably connectable bottom end adapted to connect to the fuel tank.
6. The cap of claim 1 in which the air vent is configured as a third port in the top end of the housing.
7. The cap of claim 6 further comprising a line extending from the third port for discharge of air away from the fuel tank.
8. A cap for a fuel tank of equipment at a well site during fracturing of a well, comprising:
a housing having a throat and a top end;
a first port in the top end provided with a connection for securing a hose to the cap;
a second port in the top end holding a fuel level sensor, the fuel level sensor detecting low and high fuel levels in the tank; and
a communication device connected to the fuel level sensor for communicating signals representing the low and high fuel levels from the fuel level sensor to a remote controller.
9. The cap of claim 8 in which the first port comprises an overfill prevention valve.
10. The cap of claim 8 in which the communication device comprises a wireless transceiver.
11. The cap of claim 8 in which the communication device comprises a wired channel.
12. The cap of claim 8 in which the housing further comprises a releasably connectable bottom end adapted to connect to the fuel tank.
13. The cap of claim 8 further comprising a third port in the top end for exhausting air from the fuel tank during delivery of fuel to the fuel tank.
14. The cap of claim 13 further comprising a line extending from the third port for discharge of air away from the fuel tank.
15. The cap of claim 8 in which the fuel level sensor comprises at least one of a float sensor, a vibrating level switch, or a pressure transducer.
16. The cap of claim 15 in which the fuel level sensor comprises a float sensor.
