  • Patent number: 10416095
    Abstract: A dielectric waveguide (DWG) may be used to identify a composition of a material that is in contact with the DWG. A radio frequency (RF) signal is transmitted into a dielectric waveguide located in contact with the material. The RF signal is received after it passes through the DWG. An insertion loss of the DWG is determined. The presence of the material may be inferred when the insertion loss exceeds a threshold value. The composition of the material may be inferred based on a correlation with the insertion loss. Alternatively, a volume of the material may be inferred based on a correlation with the insertion loss.

  • Patent number: 8640529
    Abstract: An apparatus and method for down hole gas separation from the multiphase fluid flowing in a wellbore or a pipe, for determining the quantities of the individual components of the liquid and the flow rate of the liquid, and for remixing the component parts of the fluid after which the gas volume may be measured, without affecting the flow stream, are described. Acoustic radiation force is employed to separate gas from the liquid, thereby permitting measurements to be separately made for these two components; the liquid (oil/water) composition is determined from ultrasonic resonances; and the gas volume is determined from capacitance measurements. Since the fluid flows around and through the component parts of the apparatus, there is little pressure difference, and no protection is required from high pressure differentials.

  • Publication number: 20130192337
    Abstract: The invention is directed towards methods and apparatus for accurately detecting the presence and concentration of an oxidant in a turbid water sample. This method is very helpful in allowing accurate and efficient (not too much nor too little) amounts of microbe killing oxidants to be introduced to water supplies that require oxidants but which at present cannot be measured properly. The method comprises the steps of: passing the water through at least one filter array, passing the filtered water to an analyzer, and then returning from the analyzer a measurement of the concentration. The filter array comprises at least one filter constructed and arranged to remove turbidity inducing material but not oxidant from the water sample. The analyzer can be a commonly commercially available analyzer that currently cannot accurately measure the oxidant concentration if the water had not been so filtered.

  • Patent number: 8490464
    Abstract: Liquid, say, an oleaginous liquid or an ink, for example, an engine oil, can be tested for aeration, entrainment and/or dissolution of a gas and/or foaming. The liquid can be tested through generation of a foam, for example, through aeration with employment of a vacuum, which can be carried out at a controlled, elevated temperature, for example, about 150° C., and the foam measured as to volume generated; and/or by testing for an entrained/dissolved gas directly, say, by drawing off the entrained/dissolved gas with a high vacuum, which can be done following aeration, for example, at a moderate temperature, for example, about 30° C. The gas can be air. Apparatus for use in such testing can include an outer, selectively sealable tube, which can be transparent, and which can serve as a vessel to contain a sample of a liquid as aforesaid to be tested; and, within the outer tube, a smaller generally vertical, inner tube also extending upward from and optionally out of the sealed outer tube.

  • Patent number: 8489341
    Abstract: A method and apparatus for monitoring fluid in a fluid line are disclosed. The apparatus includes a first capacitor and a processor in communication with the first capacitor. The first capacitor is configured to sense the capacitance of the fluid line at the first capacitor. The processor is configured to compare the sensed capacitance at the first capacitor with a reference capacitance to determine the composition of the fluid in the fluid line at the first capacitor. In some embodiments, the apparatus also includes a second capacitor. The second capacitor is configured to sense the capacitance of the fluid line at the second capacitor. The processor is configured to compare the sensed capacitance at the second capacitor with a reference capacitance to determine the composition of the fluid in the fluid line at the second capacitor.

  • Patent number: 8464572
    Abstract: A system includes a signal source that provides a first signal for measuring a gas content of a liquid sample. The system also includes an analyzer that determines the gas content of the liquid sample using a measurement of a second signal, where the second signal is based on the first signal. The system further includes an apparatus with a walled structure having a cavity. The apparatus also includes a piston that pulls the liquid sample into the cavity and pushes the liquid sample out of the cavity. The apparatus further includes at least one measurement window having at least one inner surface exposed within the cavity. The at least one measurement window receives the first signal from the signal source and provides the second signal to the analyzer. The piston could also clean the at least one inner surface, and the piston can include a reference material for calibrating the analyzer.

  • Publication number: 20130098844
    Abstract: The present invention relates to water treatment control (1, 100) of water (3) to be treated containing a chlorine disinfectant (5) stabilized by a chlorine stabilizer (6). A concentration of said chlorine disinfectant (5) contained in said water (3) will be measured (110) once before irradiating (120) said water (3) with an UV irradiation (initial chlorine concentration). After irradiating (120) said water (3) with said UV irradiation said concentration of said chlorine disinfectant 5 contained in said water 3 will be measured (130) twice (remaining chlorine concentration). A concentration of said chlorine stabilizer 6 added to said water will be determined (140) using said initial chlorine concentration and said remaining chlorine concentration for said water treatment control (1, 100).

  • Publication number: 20130086975
    Abstract: A method can be performed by adjusting a temperature of a gas sensor to a first temperature value for a first period of time and a second temperature value for a second period of time. The gas sensor signal may be measured during the first period of time to determine a first signal value and during the second period of time to determine a second value. Then, concentration information for at least one gas is calculated according to the first signal value and the second signal value. While the gas sensor signal may include information about a presence of a first gas and a second gas, the concentration information for the at least one gas may not substantially include concentration information for the second gas.

  • Patent number: 8408421
    Abstract: A dispenser using a stopcock valve has a first and second chamber. The first chamber has a flow material and is pressurized with air. The first chamber is connected to a stopcock valve that holds a second chamber which has a pressure sensor when the stopcock valve is rotated to the proper orientation. The stopcock valve is then rotated to a dispensing position where the flow material is dispensed under pressure to an outlet. By using the air pressure sensor and by taking into consideration the volume of the second chamber, the amount of flow of material can be dosed out consistently.
