    摘要: An electromagnetic flow meter is described having a pressure containing vessel or conduit through which the fluid to be metered is passed. The pressure containing vessel is formed of first and second sections which are made of respective materials having first and second magnetic permeabilities, such as stainless steel and carbon steel. A single magnetic field generating coil is provided adjacent the first section for generating a magnetic field across the pressure containing vessel.

    摘要: Compositions for various surfaces including glass, metals, ceramics, polymers, painted surfaces, and other durable non-porous materials clean surfaces while forming a durable, and long-lasting residual thin film. The thin film is self-cleaning, and can be self-disinfecting. The compositions include a combination of a surfactant and a nanoparticulate photocatalytic material (e.g., metal oxide), and may comprise additional elements such as antioxidants, perfumes, and disinfecting agents

    摘要: An electromagnetic flow meter for measuring flow rate of a fluid passing therethrough includes a conduit defining a fluid inlet, a fluid outlet and a measuring section positioned between the inlet and the outlet. The flow meter also includes a single coil for generating a magnetic field across the measuring section and electrodes for detecting induced electrical potential due to the fluid passage. The coil may be arranged to surround a section of the measuring section over a segment angle of between 140 and 180 degrees. The electrodes may be positioned so that they are offset from being opposite each other on the centerline of the measuring section, by an offset angle of between 5 degrees and 45 degrees.

    摘要: An electromagnetic flow meter for measuring flow rate of a fluid passing therethrough includes a conduit defining a fluid inlet, a fluid outlet and a measuring section positioned between the inlet and the outlet. The flow meter also includes a single coil for generating a magnetic field across the measuring section and electrodes for detecting induced electrical potential due to the fluid passage. The flow meter also includes means for conditioning the flow through the measuring section. The combination of the single coil and the flow conditioning means provides a flow meter with a desired level of accuracy. The single coil and the electrodes may be arranged so that the integral of a weight function, which defines the sensitivity of the flow meter to fluid velocity through different parts of the measuring section, over the first half of a measuring section closest to the coil is between 0.4 and 1.3 times the integral of the weight function over the other half of the measuring section.
