Abstract

A fuel dispenser comprising fuel flow piping defining a flow path from a source of fuel toward a fueling nozzle. The fuel flow piping further has a filter manifold for mounting a fuel filter thereon. A plurality of fuel handling components are disposed along the fuel flow piping. A sensor device is mounted to the filter manifold, the sensor device having at least one sensor operative to detect a sensed condition related to the fuel dispenser. The sensor device further comprises electronics to transmit a signal related to the sensed condition.

First claim

What is claimed is:

1. A fuel dispenser comprising:
fuel flow piping defining a flow path from a source of fuel toward a fueling nozzle, said fuel flow piping having a filter manifold for mounting a fuel filter thereon, wherein the filter manifold comprises an inlet filter flow passage and an outlet filter flow passage;
a plurality of fuel handling components disposed along said fuel flow piping;
a sensor device mounted between said filter manifold and the fuel filter such that an inlet sensor flow passage is in fluid communication with the inlet filter flow passage and an outlet sensor flow passage is in fluid communication with the outlet filter flow passage, said sensor device having at least one sensor operative to detect a sensed condition related to said fuel dispenser; and
said sensor device further comprising electronics to transmit a signal related to the sensed condition.

2. A fuel dispenser as set forth in claim 1 , wherein said at least one sensor of said sensor device comprises a plurality of different sensors.

3. A fuel dispenser as set forth in claim 2 , wherein said plurality of different sensors includes at least two of a vibration sensor, an acoustic sensor, an ionic sensor, and a temperature sensor.

4. A fuel dispenser as set forth in claim 1 , wherein said sensor device has a body defining the inlet sensor flow passage and the outlet sensor flow passage therethrough, said body further defining a threaded hole for attachment to a first filter mount of said manifold.

5. A fuel dispenser as set forth in claim 4 , wherein said body includes a second filter mount for attachment of said filter thereto.

6. A fuel dispenser as set forth in claim 1 , wherein said electronics to transmit a signal comprises a radio to transmit said signal wirelessly via an associated antenna.

7. A fuel dispenser as set forth in claim 6 , wherein said antenna is covered by an antenna lens.

8. A fuel dispenser as set forth in claim 1 , wherein said at least one sensor includes one or more pressure sensors operative to detect differential pressure between inflow and outflow of said filter manifold.

9. A fuel dispenser as set forth in claim 8 , wherein said one or more pressure sensors comprises a micro-electromechanical system (MEMS) differential pressure sensor positioned to be in fluid communication on a first side thereof with a fuel filter inlet and on a second side thereof with a fluid filter outlet.

10. A fuel dispenser as set forth in claim 1 , wherein said sensor device comprises a power generator to produce power for its operation.

11. A fuel dispenser as set forth in claim 10 , wherein said power generator comprises a turbine power generator that creates electrical energy during fuel flow.

12. A fuel dispenser as set forth in claim 11 , wherein said sensor device comprises one or more energy storage components.

13. A fuel dispenser as set forth in claim 12 , wherein said one or more energy storage components comprises at least one capacitor.

15. A multi-mode hydraulic sensor device for use in a fuel dispenser, said sensor device comprising:
a body mountable to a filter manifold disposed along a fuel flow path in the fuel dispenser, wherein the filter manifold defines an inlet filter flow passage and an outlet filter flow passage, and the body is mounted between the filter manifold and a fuel filter such that an inlet sensor flow passage is in fluid communication with the inlet filter flow passage and an outlet sensor flow passage is in fluid communication with the outlet filter flow passage;
a plurality of different sensors operative to detect a sensed condition related to the fuel dispenser; and
said sensor device further comprising electronics to transmit a signal related to the sensed condition, said electronics including a radio to transmit said signal wirelessly via an associated antenna.

16. A multi-mode hydraulic sensor device as set forth in claim 15 , wherein said plurality of different sensors includes at least two of a vibration sensor, an acoustic sensor, an ionic sensor, and a temperature sensor.

17. A multi-mode hydraulic sensor device as set forth in claim 15 , wherein said body defines a threaded hole for attachment to a first filter mount of said fuel dispenser and a second filter mount for attachment of a filter thereto.

18. A multi-mode hydraulic sensor device as set forth in claim 15 , wherein said antenna is covered by an antenna lens.

19. A multi-mode hydraulic sensor device as set forth in claim 15 , wherein said plurality of different sensors includes one or more pressure sensors operative to detect differential pressure between inflow and outflow of fuel through said body.

20. A multi-mode hydraulic sensor device as set forth in claim 19 , wherein said one or more pressure sensors comprises a micro-electromechanical system (MEMS) differential pressure sensor.

21. A multi-mode hydraulic sensor device as set forth in claim 15 , wherein said sensor device comprises a power generator to produce power for its operation.
