| Abstract: | A method of real time oil concentration measurement has been developed utilizing the different ultraviolet light absorption sensitivity of the oils and refrigerants with GaN ultraviolet photo sensor.The effect of velocity of flow is investigated in order to determine how it affects the concentration measurement. The technique was very reliable after compared with the standard method. |
