20090302221 | APPARATUS AND METHOD FOR OPTICALLY DETERMINING THE PRESENCE OF CARBON DIOXIDE - Apparatus for optically determining the presence of carbon dioxide within a fluid, said apparatus comprising:—a light emitting source, an optical sensing probe in contact with the fluid to analyze; optical light transmitting means in order to convey the light emitted from the light emitting source to the optical sensing probe and the light reflected by the optical sensing probe to means to discriminate between wavelengths of light beams reflected by the optical sensing probe;—means to convert wavelengths discriminated light beams into measurement data indicating presence of carbon dioxide within the fluid, wherein the optical sensing probe comprises a tip working as attenuated total reflection (ATR) absorber within the infrared wavelength. | 12-10-2009 |
20110214498 | FLOW RESTRICTION INSERT FOR DIFFERENTIAL PRESSURE MEASUREMENT - A flow rate device for measuring the flow rate of a fluid flowing through a wellbore is disclosed. The flow rate device includes a differential pressure conduit, a flow restrictor insert and a differential pressure measurement device. The differential pressure conduit is locatable in the wellbore, defines an internal bore, and is adapted to include a restriction having a cross-sectional area to increase the velocity of fluid flowing through the differential pressure conduit to create a differential pressure. The differential pressure conduit defining first and second pressure measuring stations axially spaced along the differential pressure conduit. The flow restrictor insert is located in the restriction to reduce the cross-sectional area of the restriction. The flow restrictor insert defines an internal bore having a cross-sectional area less than the cross-sectional area of the restriction. The flow restrictor insert also has a pressure measuring port aligned with the second pressure measuring station. The differential pressure measurement device has at least one pressure sensor for detecting the pressure at the first pressure station, and for detecting the pressure at the second pressure station to generate a signal indicative of the flow rate of the fluid. | 09-08-2011 |
