    • A method of measuring liquid level in a tank. An electromechanical liquid level gauge (ESG) is provided including a processor, a displacer suspended on a wire from a grooved drum having a servo motor coupled thereto to rotate the drum for balancing the displacer. A change in liquid level causes a change in a counterforce to move the ESG out of balance. The processor monitors a torque sensor output, and controls movement of the motor using a programmed apparent weight (AW) setpoint to raise or lower the displacer based on an AW derived from the torque. An associated memory stores a density compensated fixed immersion depth level gauging algorithm. The algorithm implements obtaining a density reading for the liquid, continuously corrects an immersion depth of the displacer for changes in density to provide an essentially fixed immersion depth, and calculates the liquid level from the density reading and immersion depth.
    • 一种测量罐中液位的方法。 提供了一种机电液位计(ESG),其包括处理器,从具有与其耦合的伺服电动机的带槽滚筒悬挂在电线上的置换器,以旋转鼓以平衡置换器。 液位变化导致反作用力发生变化,以使ESG失去平衡。 处理器监视扭矩传感器输出,并使用编程的表观重量(AW)设定值控制电机的运动,以根据从转矩得到的AW来升高或降低置换器。 相关联的存储器存储密度补偿的固定浸入深度水平测量算法。 该算法实现了获得液体的浓度读数,连续地校正了置换器的浸入深度以改变密度,从而提供基本上固定的浸入深度,并从密度读数和浸入深度计算出液位。

    • A sensor for sensing buoyancy force within a liquid mixture (4) stored within a storage tank (2) and an interlock employing the sensor (10) to prevent a respirable cryogenic mixture from being dispensed from the storage tank (2) with an unsafe oxygen content. The sensor (10) has a float (12) adapted to be submerged in the liquid mixture (4), thereby to exert a buoyancy force referable to the density. The buoyancy force is sensed by a load cell(26) connected to an elongate base element (18) cantilevered from the outlet (3) of the tank (2) by a bracket (38). The mounting of such sensor (10) ensures that the buoyancy force and therefore, the density of the liquid as dispensed will be measured as opposed to liquid density at some other location of the tank (2). Such sensor (10) can serve in an interlock in which a controller (32) responsive to the load cell (26) and a temperature sensor (34), also located within the outlet (3), controls a valve (36) to close the outlet (3) when the mixture has an unsafe oxygen level.

    • PURPOSE:To inexpensively obtain a small specific gravity detection apparatus with high reliability, by mounting a magnetism responsive element, the magnet provided to said magnetism responsive element and a movable magnet moving up and down with respect to said magnet in a liquid and changing the magnetic force of the magnet to the magnetism responsive element. CONSTITUTION:When the specific gravity of an electrolyte L is high in such a state that a battery is fully charged, large buoyancy is acted on a movable magnet 30 which is, in turn, brought to such a state that rising force by buoyance and the repulsive force between said magnet 30 and a magnet 28 are well balanced at a position in the vicinity of the upper side stopper 29 of a guide part 13. At this time, the magnetic force of the magnet 28 is negated by that of the movable magnet 30 and the signal output of a magnetoresistance element 18 by the magnetic force of the magnet 28 is largely lowered and a meter 21 shows a full charge state. When the battery discharges and the specific gravity of the electrolyte L is lowered, the buoyancy acting on the movable magnet 30 gradually lowers and said magnet 30 gradually lowers in such a state that the rising force by buoyancy and the repulsive force between both magnets 28, 30 are always balanced. At this time, the effect of the movable magnet 30 received by the magnet 28 is also gradually reduced and the signal output of the magnetoresistance element 18 by the magnetic force of the magnet 28 gradually rises and the meter 21 shows a discharge state.

    • PURPOSE:To accurately measure specific gravity of an electrolyte and improve durability with a simple construction by detecting a change in an electrode current along with displacement of the float due to a change in specific gravity of the electrolyte. CONSTITUTION:When a lead wire 7 is connected with one electrode of a storage battery, a current passes through an electrode 6 in contact with an electrolyte 2 at all times and gas generated from the electrode 6 is discharged through an opening 4 formed in a tube 1. Therefore, the electrolyte inside of the tube 1 has the same level as that outside of the tube 1. If specific gravity of the electrolyte 2 is higher than the preset specific gravity of a float 8 in that state, the upper end portion of the float 8 enters into the tube 1 to form a narrowed portion 9. The current reaching the electrode 6 passes through the electrolyte 2 within the narrowed portion 9, so that the current value becomes smaller. Meanwhile, if specific gravity of the electrolyte 2 is lower than the preset specific gravity of the float 8, the upper end portion of the float 8 is lowered out of the tube 1 and the narrowed portion 9 is not formed, thus resulting in an increased current passing through the electrode 6. It is hence possible to accurately detect a change in specific gravity of the electrolyte 2 based on a change in the current passing through the electrode 6.
    • 目的:为了精确测量电解质的比重,通过检测电极电流的变化以及由于电解质的比重变化引起的浮子位移,可以通过简单的结构提高耐久性。 构成:当引线7与蓄电池的一个电极连接时,电流始终通过与电解质2接触的电极6,并且从电极6产生的气体通过形成在管中的开口4排出 因此,管1内的电解质与管1的外部具有相同的水平。如果电解质2的比重比该状态下的浮子8的预定比重高,则上端部 浮子8进入管1中以形成变窄部分9.到达电极6的电流在变窄部分9内通过电解质2,使得电流值变小。 同时,如果电解液2的比重低于浮子8的预设比重,则浮子8的上端部从管1下降出来,并且不形成变窄部9,结果增加 电流通过电极6.因此,可以基于通过电极6的电流的变化来精确地检测电解质2的比重变化。
