摘要:
A fluid level probe for use in a tank containing a first fluid, including a probe shaft, a first float with a first magnet that is slidably disposed for movement along the probe shaft and adapted to float at the top surface of the first fluid, a second float with a first magnet that is slidably disposed for movement along the probe shaft beneath the first float and adapted to float within the first fluid, and electronics adapted to determine a first distance between the first magnet of the first float and the first magnet of the second float which is used to determine a first density of the first fluid.

The method can determine a density of concrete based on the measured buoyancy of a buoy immersed in fresh concrete contained in a ready mix drum and rotatable therein as the drum is rotated, the method can include obtaining a first measurement of a force applied to the buoy while the buoy is being moved tangentially in the fresh concrete, obtaining a second measurement of a force applied to the buoy while the buoy is being moved tangentially in the fresh concrete by rotation of the cylindrical wall, obtaining an indication of the buoyancy of the buoy in the concrete including factoring out the yield effect based on at least the first measurement and the second measurement.

A density measuring device (1) is described having: a housing (4), internally defining a first chamber (5), designed to contain a fluid (2) the density of which it is desired to measure, and housing, in a measurement operating condition, a float (6), designed to be immersed in the fluid (2); and an electronic circuit (22) that detects a value of the density as a function of a thrust sustained by the float (6) due to the effect of the fluid (2); the housing (4) further defines a second chamber (15), designed to contain a filling gas and to house the float (6) in a cleaning operating condition of the float (6), distinct from the measurement operating condition, for removing gas bubbles and/or solid particles that have adhered to an outer surface of the float during the measurement operating condition.

The battery charge indicator cage is molded as a single integral piece with two cores coming in and shutting off against each other. The battery charge indicator cage includes an internal diagonal channel in which a colored ball or balls traverse dependent upon the presence of a fluid of at least a predetermined density. A stem is formed within the diagonal channel in order to form the one-ball embodiment. This stem is removed in order to form the two-ball embodiment.

摘要:
Eine Vorrichtung (10) zur Bestimmung des Alkoholgehalts von Feuchtmittel für den Offsetdruck umfasst eine Messzelle (12), die einen Zulauf (16), über welchen der Messzelle (12) das Feuchtmittel zugeführt wird, und einen Überlauf (20) aufweist, welcher den Feuchtmittelpegel in der Messzelle (12) konstant hält. Die Vorrichtung umfasst ferner einen Schwimmer (24), der in der Messzelle (12) angeordnet ist und dessen vertikale Position von einer Positionserfassungseinrichtung (36) erfasst wird, um die Dichte des Feuchtmittels zu messen. Um die Messgenauigkeit zu verbessern ist der Messzelle (12) eine Abscheidekammer (14) vorgeschaltet, in deren Volumen sich das Feuchtmittel so weit verlangsamen und beruhigen kann, dass in dem Feuchtmittel enthaltene Luftblasen (50) entweichen, bevor das Feuchtmittel in die Messzelle (12) eintritt.
