摘要： Method and apparatus for detecting and/or monitoring the presence of hydrocarbons in a fluid medium at a remote location, by sensing the presence of hydrocarbon-based fluid in the fluid medium in the remote location, generating a signal indicative of the sensed fluid, and transmitting the signal to monitoring means for indication of hydrocarbon contamination. The apparatus has multiple sensors at different vertical levels for sensing the fluid medium at a plurality of levels within the fluid.

摘要： A mass sensoring system for monitoring the amount of fluid in a storage tank with an accuracy high enough to determine both the quantity present and the potential loss of fluid at a loss rate of 0.05 gal/hr or at least 0.1 gal/hr. The system utilizes a pressure sensor positioned at the bottom of the tank and in contact with the fluid. This device includes a bellows unit whose displacement is correlated to changes in the mass of fluid in which it is immersed, and a transducer for monitoring the position of the bellows, wherein the interior of the bellows unit is in the same atmosphere as the sensor, and the sensor is in communication with the vapor pressure immediately above the fluid in the tank. The outside of the bellows is subjected to the stored fluid. A multiple-capsule bellows assembly is coupled to an LDVT transducer in a thermal-expansion-cancelling configuration of the invention.

摘要： A wind sensor includes first and second elements in an orthogonal axis arrangement and a calibration data array comprising first calibration data associated with the first element and second calibration array data associated with second element. An anemometric processor determines a wind speed (S) and direction (W) for an airflow received by the first and second elements using a first electrical parameter associated with the first element and the first calibration array data and a second electrical parameter associated with the second element and the second calibration array data. A wind sensing probe can have a pair of wind sensing elements, wherein each element has a core formed of a low specific heat, low density, high temperature plastic polymer, with two metal leads extending from the ends of core. A wind sensing element can include a fine Nickel alloy coil wound around an aforementioned core.
