Optical radiation sensor system and method for measuring radiation transmittance of a fluid |
摘要 |
A process for measuring transmittance of a fluid with first and second radiation wavelengths includes (i) positioning a polychromatic radiation source and a polychromatic radiation sensor in a spaced relationship to define a first thickness of fluid; (ii) detecting a first radiation intensity corresponding to the first wavelength at the first thickness; (iii) detecting a second radiation intensity corresponding to the second wavelength at the first thickness; (iv) altering the first thickness to define a second thickness; (v) detecting a third radiation intensity corresponding to the first wavelength at the second thickness; (vi) detecting a fourth radiation intensity corresponding to the second wavelength at the second thickness; and (vii) calculating radiation transmittance of the fluid in the radiation field from the first radiation intensity, the second radiation intensity, the third radiation intensity and the fourth radiation intensity.
