摘要： A method and handheld apparatus for the measurement of liquid density comprising a handheld enclosure which encases a differential pressure transducer having each pressure orifice connected by separate tees to separate hollow bubble tubes. Each bubble tube is connected on one end to a common micro-pump providing a balanced and relatively constant gas flow in each hollow bubble tube. The other ends of the bubble robes are terminated outside of the enclosure at relatively fixed and different distances from the enclosure in an arrangement that provides for the bubble tubes to be encased in a free hanging probe that will hang substantially vertical and will access liquid chamber diameters down to 1/4 inch. The apparatus measures density by vertically orienting the open ends of each hollow bubble tube in a liquid and measuring the differential pressure at the open ends of the bubble tubes created by the weight of the liquid at their respective depths. The apparatus also compromises an electronic circuit which takes the output signal from the differential pressure transducer, manipulates it and displays a properly calibrated and steady reading.

摘要： This invention provides a method and apparatus for transmitting and sensing liquid pressure (head) and liquid level (depth) in flow metering, tide gauge and liquid salinity or slurry density measurement applications. The invention essentially eliminates the effect of pressure sensor temperature variations and the effect of long-term pressure sensor signal drift on pressure sensing accuracy by resetting the zero and gain of the pressure sensor prior to pressure measurement. A variety of sources of a known differential pressure may be used to reset the gain of the differential pressure sensor by simultaneously exposing both sides of the differential pressure sensor to the known differential pressure. In one embodiment of the invention, the head loss through exhaust port of a spring-biased comparitor is the known pressure differential used to reset the pressure sensor gain. In another embodiment, a U-tube manometer is used to set a known differential pressure across an adjustable differential pressure regulator or an adjustable spring-biased comparitor and that pressure differential is used. The invention provides accurate bubbler pressure measurement under conditions of rapidly varying liquid head by means of a single calibration of a differential pressure sensor instead of sequential calibrations of a gauge pressure sensor. The present invention provides a compact and lightweight manifold-mounted pneumatic integrated circuit and a method for in situ recalibration of relatively inexpensive pressure sensors.
摘要翻译：本发明提供了一种用于在流量计，潮汐计和液体盐度或浆料浓度测量应用中传输和感测液体压力（头部）和液位（深度）的方法和装置。通过在压力测量之前复位压力传感器的零点和增益，本发明基本上消除了压力传感器温度变化的影响以及长期压力传感器信号漂移对压力感测精度的影响。可以使用已知压差的各种来源，通过同时将差压传感器的两侧暴露于已知的压差来重置差压传感器的增益。在本发明的一个实施例中，通过弹簧偏置的比较器的排气口的头部损失是用于复位压力传感器增益的已知压力差。在另一个实施例中，使用U型管压力计来设置跨越可调压差调节器或可调节弹簧偏置的比较器的已知压差，并且使用压力差。本发明通过差压传感器的单次校准而不是表压式传感器的顺序校准，在快速变化的液体头的条件下提供精确的起泡器压力测量。本发明提供了一种紧凑且重量轻的歧管安装的气动集成电路和用于相对便宜的压力传感器的原位重新校准的方法。

摘要： An apparatus for measuring the density of a liquid or of a suspension of solids in a liquid is disclosed. The apparatus comprises two pressure sensors adapted to be mounted in the liquid so that the two sensors are vertically at predetermined levels apart, a differential pressure transducer, and proper tubings including a differential pressure zeroing device interconnecting the pressure sensors to the differential pressure transducer, for providing an output proportional to the density of the liquid which is compensated for the differential pressure caused by the differential neight of said pressure sensors in the liquid. In a preferred embodiment of the invention, the differential pressure zeroing device is a pair of U-tubes filled with liquid and the tubings comprise gas filled tubings interconnecting one branch of each U-tube to respective pressure sensors and the other branch of each U-tube to the differential pressure transducer.
