초록 ▼

An optical spectral sensing device for determining at least one property of a fluid. The device has an elongated porous body, a first end and a second end, a solid-state optical emitter at the first end of the body oriented to emit radiation toward the second end of the body, and a solid-state optical detector at the second end of the body oriented to detect radiation emitted by the optical emitter and to output a signal responsive to absorption of radiation. The device is configured to determine depth of a fluid based on the signal output by the optical detector.

1. An optical spectral sensing device for determining at least one property of a fluid, the device comprising: an elongated body having a first and a second end;an optical emitter at the first end of the body and oriented to emit radiation toward the second end of the body;an optical detector at the second end of the body oriented to detect radiation emitted by the optical emitter, and configured to output a signal representative of the detected radiation; andan electronics package for providing energy for the optical emitter and for receiving the signal representative of the detected radiation generated by the optical detector,wherein the electronics package is configured to, when the first end is submerged in a fluid and the second end is above the fluid, based on the signal generated by the detector, output at least one value indicative of the fluid depth, andwherein the device is configured to determine fluid depth responsive to absorption of emitted radiation by the fluid. 2. The optical sensing device of claim 1, wherein the electronics package further comprises a memory device configured to store a predetermined absorption vs. depth relationship for the fluid to be measured, and wherein the electronics package is configured to determine a value indicative of the light absorbed by the fluid, and output at least one value indicative of the fluid depth via a comparison of the value indicative of absorbed light and the predetermined absorption vs. depth relationship. 3. The optical sensing device of claim 1, wherein the electronics package is further configured to output at least one value indicative of the fluid composition. 4. The optical sensing device of claim 1, wherein the elongated body is porous. 5. The optical sensing device of claim 4, wherein the porous body is hollow, and the optical emitter and optical detector are mounted to transmit and receive radiation within a hollow interior of the porous body. 6. The optical sensing device of claim 1, wherein the optical emitter comprises a solid-state optical emitter. 7. The optical sensing device of claim 6, wherein the optical emitter comprises at least one light-emitting diode (LED). 8. The optical sensing device of claim 1, wherein the optical detector comprises a solid-state optical detector. 9. The optical sensing device of claim 8, wherein the optical detector comprises a silicon photodiode. 10. The optical sensing device of claim 1, wherein the optical detector is integrally formed on an electronic control board. 11. A method for determining the depth of a volume of fluid, comprising: radiating energy through a volume of fluid via an optical emitter arranged at a first end of a first end of an elongated body and oriented to emit radiation toward a second end of the elongated body;receiving the energy radiated by the optical emitter through the volume of fluid at an optical detector arranged at the second end of the elongated body;calculating, by an electronics package, a value indicative of the energy absorbed by the fluid via a comparison between the energy radiated by the optical emitter and the energy received by the optical detector, anddetermining, by the electronics package, the depth of the fluid based at least in part on the calculated value indicative of the energy absorbed by the fluid. 12. The method of claim 11, wherein the step of determining the depth of the fluid comprises comparing the calculated value indicative of absorbed energy to a predetermined value to determine the depth of the volume of fluid. 13. The method of claim 11, wherein the elongated body comprises a porous body, and the optical emitter and optical detector are mounted to transmit and receive energy within a hollow interior of the porous body. 14. The method of claim 13, wherein at least one of the ends of the porous body is submerged in the volume of fluid simultaneously with the steps of radiating and receiving energy. 15. The method of claim 11, further comprising determining composition of the fluid by analyzing the energy received at the optical detector.
