Abstract: An energy loss detecting apparatus for measuring the rate of flow of the vapor phase of a bi-phase fluid flow, in the presence of an unknown quantity of the liquid phase, by separating the vapor phase from the liquid phase and producing a signal representing the vapor phase flow rate. The apparatus includes a hollow separator casing provided with a tube communicating with at least one of the inlet opening and outlet opening of the casing and facing thereinto. A wall seals the interior of the tube from the interior of the casing except at reduced diameter holes in the wall, the diameter of the holes being less than the inside diameter of the tubes at the wall. Energy loss due to a faulty steam trap is measurable by interposing the vapor flow rate measuring apparatus in a steam line between a steam consuming device and the steam trap.

Abstract: An energy loss detection system includes an apparatus (22) for measuring loss of the vapor phase of a bi-phase fluid. Such apparatus is interposable in an energy transfer circuit downstream of an energy consumer device (14), intended to take energy from the bi-phase fluid by converting the vapor phase to liquid, and upstream of a potential energy loss device (20). The apparatus includes a separator (24) for separating the vapor and liquid phases of the bi-phase fluid into separate flow paths. A probe (51) senses the flow rate of the vapor phase through the separator and produces a signal related thereto. An output apparatus (72) includes a readout device (79) responsive to the probe signal for producing a display indicative of vapor flow rate and hence of energy loss downstream of the separator.

Abstract: A flowmeter for measuring flow of fuel to a combustion engine comprises a transducer including a turbine the vanes of which interrupt the light between a light source and a photosensitive device when the turbine rotates, the transducer being mounted with its axis vertical for fuel to flow upwardly past the turbine, a swirl chamber for eliminating gas and vapor bubbles from the fuel before it enters the transducer, and a non-return valve to prevent reverse flow of fuel through the transducer.

Abstract: A multiphase flow measurement system determines the individual total flow rates of the water, gas, and oil components in a production fluid mixture from a subterranean well. The system includes a mass flow measurement unit which is coupled to the outlet of the well for measuring a total mass flow rate of the production fluid mixture. After the mass flow rate has been measured, a sample portion of the production fluid is supplied to a test separator tank system which is utilized to determine individual sample flow rates of the water, gas, and oil components in the sample portion of the production fluid. A central control unit is responsive to the individual sample flow rates and the mass flow measurement for determining the individual total flow rates of the water, gas, and oil components at the well head.

Abstract: An apparatus for measuring and/or sampling the milk-yield of a cow during milking is described. The apparatus comprises a housing with a milk inlet and a milk outlet and a rotation-symmetric distributing means mounted in a drain chamber. A buffer chamber is formed in the housing above the drain chamber, in which buffer chamber the incoming milk stream is received. The buffer chamber is connected to the drain chamber by a cylindrical bore formed in its bottom wall, said bore being coaxial with the distributing means. Means are provided adapted to permit a milk flow to the distributing means through the cylindrical bore only when a predetermined milk quantity is received in the buffer chamber, said means interrupting said milk flow at a second smaller milk quantity in the buffer chamber. The distributing means provides a radial flowing milk film a portion of which is conducted to a measuring means through a receiving chamber.

Abstract: This invention is a compact, precise, and relatively simple device for use in determining the average rate of flow of a liquid through a conduit. The liquid may be turbulent and contain bubbles of gas. In a preferred embodiment, the flowmeter includes an electrical circuit and a flow vessel which is connected as a segment of the conduit conveying the liquid. The vessel is provided with a valved outlet and is partitioned by a vertical baffle into coaxial chambers whose upper regions are vented to permit the escape of gas. The inner chamber receives turbulent downflowing liquid from the conduit and is sized to operate at a lower pressure than the conduit, thus promoting evolution of gas from the liquid. Lower zones of the two chambers are interconnected so that the downflowing liquid establishes liquid levels in both chambers.

Abstract: A pressure tap having utility in an environment of a solid-gas phase process flow includes a tubular coupling part having attached over a passage therethrough at an end opening thereof exposed to the flow a grating of spaced bars, and affixed internally across a passage therethrough so as to cover over an opening therein a screen which maintains contained within the passage between it and the grating a matrix of smooth spheres. The grating bars are so oriented by the disposition of the aforesaid end opening with respect to the flow such that accumulations of solids therebetween tending to bridge the opening are removed therefrom by the flow.

Abstract: A system is provided for delivering any of two or more liquids from their respective storage tanks into a tank truck or the like while avoiding contamination of the liquid being delivered with any significant amount of a previously delivered liquid. Means are provided for collecting vapor from the tank truck and for minimizing evaporation losses of the liquid being delivered.

Abstract: An inverted bucket having a pair of gas entrapping compartments alternatively positioned over the gas discharging end of an inlet conduit submerged within a body of liquid. The bucket is pivotally displaced between its operative positions by the buoyant force exerted by a preset quantity of gas accumulated. The gas is accumulated in one compartment while the gas previously accumulated in the other compartment escapes. Displacement of the bucket is detected and registered by a counter mechanism.

Abstract: Combination of a flow meter and a bubble trap for blood which has been extracted for extra-corporeal treatment, in particular for dialysis. Said combination comprises a container divided by a vertical partition wall into a vertically elongated inlet chamber having an inlet opening receiving the blood flow to be measured and treated, and an outlet chamber of substantially greater cross-section than the inlet chamber and in liquid communication with an outlet opening. According to the invention, a narrow passage with a substantially smaller cross-section than the inlet opening is provided through the partition wall, preferably near the lower end of the same, causing the liquid level in the elongated inlet chamber to rise substantially above the level of said narrow passage. The difference between the liquid levels in the respective chambers will be an indication of the blood flow rate through the container, a pressure equalization opening being provided through the wall above said liquid levels.

Abstract: A liquid dispensing installation includes an air separator, a volume-meter, a main flow valve in a main conduit, and a bypass valve in a conduit which bypasses the main flow valve. The main flow valve and the bypass valve are normally open during liquid dispensing operations, and both valves are closed in response to reduced pressure in the installation or when a given liquid level is reached in the liquid-receiving container. When the valves are closed in response to reduced pressure, both valves or preferably only the bypass valve will reopen when pressure is restored to a given level.
