摘要： 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.

摘要： The present invention relates to a novel device that enables a person to gauge the brine density in solar salt works from afar without recourse to sampling of the brine. The devicenullwhich can be considered as an improvisation over the conventional laboratory type Baume meternullcan be placed directly in the salt pan. The device remains sunk, and therefore invisible, until the desired density of brine is approached. Thereafter it gradually floats up and becomes visible from afar. From appropriate markings on the rod connected to the top end of the device, it can be gauged whether the brine is yet to attain the desired density, or has attained the desired density range, or has exceeded the desired density range. The device is resistant to corrosion and able to combat extreme weather conditions prevailing in solar salt works. The control of brine density from afar helps eliminate the need for frequent sampling of brine for density measurement that would make adherence to the optimum process of salt production easier. The methodology can be extended to production of other marine chemicals such as carnallite and kainite.
摘要翻译：本发明涉及一种新颖的装置，其使得人们能够远距离地测量太阳能盐工程中的盐水密度，而不需要对盐水进行取样。该设备可以被认为是常规实验室波美表的即兴表现 - 可以直接放在盐盘中。设备保持沉没，因此不可见，直到接近所需的盐水密度。此后，它逐渐浮起，从远处变得可见。从连接到设备顶端的杆上的适当标记可以测量盐水是否仍然达到期望的密度，或者达到期望的密度范围，或者已经超过了所需的密度范围。该设备耐腐蚀，能够抵御太阳能盐工程中极端天气条件。从远处控制盐水密度有助于消除对频繁取样盐水进行密度测量的需要，这将使得遵守盐生产的最佳过程更容易。该方法可以扩展到其他海洋化学品的生产，如光卤石和卡锡沸石。

摘要： A density sensor includes a stationary housing (12) and a reciprocating body (22) with a float (26) attached thereto to provide a buoyant force. The reciprocating body (22) is connected to a piston (32) by a reciprocating rod (34). The piston (32) is operable to move within a bore (30). A second piston (52) is also disposed in the bore (30) and is coupled to the piston (32) by a spring (54). A transducer (44) is disposed at the other end of the bore and is connected to the piston (52) through hydraulic fluid disposed in a hydraulic chamber (56). The spring (54) is functional to remove low frequency components of acceleration from the buoyant force and the hydraulic fluid disposed in the hydraulic chamber (56) is operable to remove high frequency acceleration components from the buoyant force. In this manner, the transducer (44) can be isolated from both high and low frequency acceleration components.
