  • Patent number: 10663402
    Abstract: An apparatus and method of measuring free water, also known as undissolved water, in hydrocarbon fuel. A housing defines a chamber and is adapted to receive a fluorescein impregnated filter pad in the chamber between a UV light source and a light sensor. The filter pad is exposed to the fuel causing the free water to react with the fluorescein and is then placed within the chamber between the light source and sensor. The UV light strikes one side surface of the filter pad and excites the reacted fluorescein thereby causing light emitted from the UV light reacted fluorescein filter pad opposite side surface to strike the light sensor. An output from the light sensor is proportional to the fluorescein on the filter pad which reacted with free water and is used for providing an output value representative of the free water present in the hydrocarbon fuel.

  • Publication number: 20150050743
    Abstract: The present invention relates to the use of reversible dimerization of methylene blue (MB) for sensing humidity. The invention preferably uses titanate nanowires coated with MB. The self-organizational properties of MB on the surface of this nanostructured material studied by spectroscopic means revealed that the light absorption properties of the MB molecules are humidity dependent. Based on the observed humidity dependent metachromasy, we fabricated a humidity sensor using optical fiber technology which is adapted for medical, industrial or environmental applications. The sensor operates with excellent linearity over the relative humidity (RH) levels ranging from 8 to 98%. The response and recovery time can be reduced to 0.5 s while the device exhibits excellent reproducibility with low hysteresis. These performances allow the implementation of the sensor in a breathing monitoring system. Furthermore, the metachromasy was observed for other dyes.

  • Patent number: 7407625
    Abstract: Systems and methods for measuring the moisture and sediment content of a petroleum sample. In one embodiment, a sample to be tested is collected in a field bottle. The sample from the field bottle is then transferred from the field bottle, and into and through a measurement column containing a high-uptake gelling agent, such as a superabsorbent polymer. The sample's moisture is determined by measuring the expanded volume of the high-uptake gelling agent. The measurement column also contains a sediment measurement section having a sediment filter and a sight glass with graduations to measure the sediment content of the sample.

  • Patent number: 7189572
    Abstract: A measuring method first calculates the conductivity of an electrolyte membrane based on measured output voltage and output current of a fuel cell. The water content of an oxidant channel as an index of present water content (PWC) of the fuel cell is calculated based on the calculated conductivity and the other measured physical quantities of the fuel cell. Further the method calculates the water content of the oxidant channel after the inside of the fuel cell reaches a steady state as an index of future water content (FWC) using the measured physical quantities. The PWC index and FWC index are compared, and it is finally determined, based on the result of the comparison and the difference between the previous and present values of the conductivity, whether the water content of the fuel cell is short or excessive at the present time.

  • Patent number: 7112443
    Abstract: A library of material samples is screened for properties such as permeability. A library of material samples is provided. A stimulus such as an exposure to a permeate fluid is provided to each member of the library. A response of each of the material samples due to the stimulus is measured and the response, the stimulus or both are recorded and related to provide data. Thereafter, the data is analyzed to reach conclusions regarding the properties of the material samples.

  • Patent number: 7109037
    Abstract: The water-based resist stripping liquid management apparatus according to the present invention manages in an adjusting bath a water-based resist stripping liquid that is used in resist stripping equipment. In this apparatus, an absorptiometer that measures the water concentration in the water-based resist stripping liquid and an electrical conductivity meter that measures the degraded component concentration in the water-based resist stripping liquid are connected to a resist stripping treatment bath (adjusting bath) via pipelines, and at least one of a resist stripping stock liquid, a resist stripping reclaimed liquid, pure water, and a premixed resist stripping new liquid are fed into the resist stripping treatment bath in accordance with the measurement values obtained. As a result, the resist stripping performance of the water-based resist stripping liquid can be stably maintained, the amount of liquid used can be reduced, and the time for which operation is shut down can be reduced.
