摘要： This invention relates to a method and apparatus for a liquid mass non-venting flowmeter. The flowmeter apparatus gives correct flow regardless of changes in density, viscosity, or composition of the liquid and corrects flow in spite of errors common in currently used flowmeters, such as calibration shifts, restricted orifices and/or bearing drag and blade wear of turbine meters. The non-venting characteristic allows use with toxic and corrosive materials.
摘要翻译： 本发明涉及一种液体质量非排气流量计的方法和装置。 无论液体的密度，粘度或组成如何变化，流量计都能提供正确的流量，尽管当前使用的流量计有常见的误差，例如校准位移，限制孔和/或承受涡轮流量计的阻力和叶片磨损 。 不通风特性允许使用有毒和腐蚀性材料。

摘要： A rotatable hunting blind providing a 360° field of vision about the blind with almost one-hundred percent concealment is disclosed. Construction of the blind on a circular frame and the type of exterior covering which shields the hunter from the vision of prey is discussed. The method of operation of the rotatable blind is discussed.
