At least one sealing element is arranged on the measuring tongue, by way of which the measuring rod can be sealed in relation to a guide tube for guiding the measuring rod.

Abstract: Invention is a device to allow a person to self-measure hydrostatic weight. The method comprises of using the device (Buoyometer) in a pool or other body of liquid of known density to counter the force of gravity pulling the body downwards. The point of neutral buoyancy—that is the point where the Buoyometer's buoyancy exactly equals the gravitational force is measured and from that hydrostatic weight is calculated. Hydrostatic weight is then used to assess body density—and thus body composition—using previously determined empirical equations.

Abstract: An oil level sensor assembly for an oil tank includes a cell with a first set of holes along the cell, an oil level sensor within the cell that is configured to be inserted into and removed from a bottom of the cell, and a ball valve column within the cell and adjacent to the oil level sensor. The ball valve column is rotatable, has ball valves that correspond with the first set of holes along the cell, and is configured such that the ball valve column is rotatable to an open position aligning the ball valves with the first set of holes to allow oil to access the oil level sensor and rotatable to a closed position misaligning the ball valves with the first set of holes to prevent oil from accessing the oil level sensor.

Abstract: The present embodiments include assemblies and methods for releasably sealing a dipstick tube with a piston valve assembly in a sealable engine fluid measurement probe assembly. In an embodiment, the piston valve assembly is integrated in a handle portion of the sealable engine fluid measurement probe assembly. The seal may be established with an o-ring positioned on an outer diameter of a portion of the sealable engine fluid measurement probe assembly that is configured to be inserted into the dipstick tube. A port or opening on either side of the o-ring is coupled to the piston valve, or other equivalent valve assembly, for allowing air or other gases to bypass the o-ring, thereby releasing the seal between the sealable engine fluid measurement probe assembly and the dipstick tube.

Abstract: An oil level gauge structure with an oil level gauge attachment hole functioning as an oil filling opening provided in a casing of an engine with an oil level gauge for closing up the attachment hole. The oil level gauge has a columnar portion formed on the lower end side of an external thread. The columnar portion has a predetermined length and is continuous with the external thread for attaching the oil level gauge to the casing. A guide hole into which the columnar portion is fitted to restrict the position of the columnar portion is provided on the lower end side of an internal thread of an attachment hole of the casing. The columnar portion of the oil level gauge is formed to have such an axial length that the lower end of the columnar portion exceeds the depth of the internal thread of the casing.

Abstract: A portable draft measurement device for measuring the draft of a vessel including a tube having an upper end, a lower end, and an interior volume between the upper and lower ends. The device includes a valve fixed to the lower end of the tube, and a resiliently biased valve actuator coupled with the valve and accessible through the upper end of the tube for selectively opening and closing the valve. Selectively opening the valve with the lower end of the tube immersed in the water in which the vessel floats, produces a level of water within the interior volume of the tube indicative of a water-line on the vessel. Selectively closing the valve retains the level of water within the interior volume, whereby the device can be removed from the water and transported to a location where the level of fluid can be measured as against a measuring tape observed through the tube.

Abstract: A portable sampling system and method for use with a cargo tank's vapor control valve or other suitable tank entry device to enable an operator to extract and bottle a product sample in place without transfer of the collected sample to another container thereby using the same container for both collection and bottling and without transfer of the collected sample through an open atmosphere. A built-in sampling valve and sample bottle fill attachment are associated with a hand held gauging apparatus for collection of the product sample free of human contact therewith, a vapor return hose assembly couples the built-in sampling valve and bottle fill attachment to the gauging apparatus for eliminating vapor release to the atmosphere and to protect an end user from possible exposure to toxic vapors.

Abstract: A sludge sampler for industrial settling ponds has a handle and an insertion tube of known graduated length so that the sampler may be embedded in sludge at a known depth. At the bottom of the insertion tube is a frame which holds a sampler container jar and which terminates downwardly in a thin walled insertion cone. A lever at the top slides a rod and lifts a cap on the jar so that free flowing sludge may fill the jar. The jar is held in a cage pivoted on the frame. The center of the cover and one edge of the cage are connected by pivoted links. As the cover is lifted, the cage is tipped, tipping the jar to receive the sludge. As the lever is returned to its closed position, the jar-capturing cage is returned to its upright position, the cover is lowered, the jar is covered before the insertion tube is lifted and the cage, the frame , the cone and the jar are lifted out of the sludge.

A valve member is carried on the rod lower end and includes an O-ring which contacts a valve seat provided in the stick lower end when the valve member is moved between an open position which admits liquid to the sample tube and a closed position. A valve operator at the stick upper end moves the valve member between the open and closed positions.

Abstract: Apparatus for determining whether a liquid in a liquid reservoir is above a certain level includes suction means operable by a user to create suction when the user desires to determine if the liquid in the reservoir is above the certain level, a conduit extending from the suction means and adapted to be positioned in the reservoir so that a passage in the conduit which communicates with the suction created by the suction means opens into the reservoir above the liquid therein when the liquid is below the certain level, and indicator for indicating whether or not the passage in the conduit is opening into the reservoir above the liquid therein. The indication that the liquid is above the certain level is given by either observing that liquid is being drawn into the passage or that the passage opening is closed. This may be done by observing the liquid itself in the passage or an indicating reservoir, or observing the operation of the suction means which given an indication of flow into the passage.

Abstract: The invention relates to a freeboard measuring device which comprises an elongated housing having a rectangular cross-section form, a central part of the device body.

The fins are triangular in cross section, with the tops of the triangles facing outwardly and providing the device with streamlined characteristics. The base of the triangles does not exceed in length the depth of the housing. The central portion has a main chamber for housing a gauging stick. The main chamber is divided into a lower and upper secondary chamber with the lower chamber having water ingress and separated from the upper chamber by a separation wall with openings to allow water to enter the upper chamber. The lower chamber has a packing of fibrous material to prevent water turbulence.

Abstract: A telescopically collapsible depth gauge-analyzer which has one mode of operation that results in a sample being collected as the device is lowered through a body of the liquid of interest. In a second mode of operation, liquid is not allowed to flow into the device until it reaches the bottom of the body of liquid and an inlet valve in the bottom of the device is opened. The depth gauge-analyzer is equipped with an arrangement which allows the inlet valve to be opened and the collected liquid to be drained from the device without contacting the user. Visual and/or audible indicators make the user of the device aware that the liquid of interest is flowing into it and that the drawing of a sample has been completed.
