摘要： An apparatus for determining a vertical level or density of a material column including one or more of a granular solid, a wet granular solid, a slurry, and a suspension, the apparatus having a support member; and at least one measurement module, wherein the measurement module includes a support arm mounted to the support member and extending outwardly from the support member; a displacer mounted to the support arm, and a force measurement device configured to measure a force attributable to a mass of the displacer mediated by a buoyancy of the displacer in the material column, wherein the measurement module has a data connection to a data processing unit for transmitting measurement data from the measurement module to the data processing unit to generate level or density information about the material column.

摘要： A hydrometer device according to an example includes a floating waterproof device container, and a liquid level sensor positioned in the device container to sense an immersion level of the device container when the device container is floating in a container of liquid. The hydrometer device further includes a conversion circuit positioned in the device container to convert the sensed immersion level to a digital value, and a controller positioned in the device container to determine a liquid density value for the liquid based on the digital value.

摘要： A digital hydrometer and methods of digitally displaying a specific gravity measured by a hydrometer are provided. The digital hydrometer can comprise a base, a displacement vessel, an inductive distance sensor, an output circuit, and a hydrometer float. The displacement vessel and inductive distance sensor can be mounted in or on the base. The displacement vessel can hold a displacement fluid. The hydrometer float can float in the displacement fluid. The output circuit can be in electrical communication with the inductive distance sensor and comprise a digital display device configured to display a digital value that is commensurate with a change in impedance attributable to the proximity of a metallic object, in the hydrometer float, to the sensor or its inductor. The digital value can be a specific gravity of the displacement fluid.

摘要： A system and sensor for remotely monitoring the state of the condition of the electrolyte within each of the battery cells of a power supply is disclosed. The system includes a sensor having a dual ball-float and track arrangement for shuttering a pair of light sources and so as to independently detect and differentiate predetermined low electrolyte specific gravity and a low level of the electrolyte. Two multiplexing units receive the sensor signals and display separate indications of each battery and the states detected. The detector uses a gravity responsive ball disposed within a track that shutters one light source at a predetermined low specific gravity and a second level responsible ball within a second track located above the gravity track and ball. The level ball has a specific gravity which is less than that of the specific gravity responsive ball and shutters the second light source at a predetermined low electrolyte level independently of changes in the specific gravity of the electrolyte.

摘要： A specific gravity sensing instrument in which a closed cell having, at least in part, highly compliant walls is completely filled with either a reference liquid, and is completely immersed in a sample liquid to be measured, or conversely the cell is completely filled with the sample liquid and completely immersed in the reference liquid, in either case the specific gravity of the sample liquid is determined by the buoyancy of the cell.

摘要： THIS INVENTION RELATES TO A DEVICE FOR DETERMINING PRINCIPALLY THE CHANGES IN SPECIFIC GRAVITY OF A FLUID ON A CONTINUOUS BASIS. THE DEVICE INCLUDES A VERTICALLY EXTENDING CHAMBER CONTAINNG A PLURALITY OF FLOTABLE ELEMENTS. EACH ELEMENT IS ADPATED TO FLOAT AT A DIFFERENT SPECIFIC GRAVITY. AS FLUID PASSES THROUGH THE CHAMBER, FIRST ONE AND THEN ANOTHER ELEMENT WILL FLOAT OR SETTLE, DEPENDING UPON THE SPECIFIC GRAVITY OF THE FLUID. CHANGES IN SPECIFIC GRAVITY OF THE FLUID WILL BE INDICATED BY THE RISE R FALL OF THE ELEMENTS IN THE FLUID.
