Flow Meter Abstract: A flow meter includes a tubular member having a main passage in which fluid flows. A branch passage member disposed in the main passage has a branch passage in which the fluid flows. A support member connects the branch passage m...
Flow Meter Abstract: In an area flow meter, float 22 made of material larger in specific gravity than a fluid being measured is movably disposed in vertical pipe 21. Magnet 23 in the float 22 has its north and south poles aligned vertically to produc...
Flow Meter Abstract: An adapter for a meter chamber provides proportional metering of a flow through a maincase that is sufficiently accurate at large flow rates to avoid the unmetered loss of significant quantities of water. An essentially unobstruc...
Flow Meter Abstract: An apparatus and method for measuring the flow rates of each component of two-phase flow consisting of a gas and a liquid or three-phase flow consisting of water, oil and gas, including a first volumetric flow-meter stage, and se...
Flow Meter Abstract: An electronic fluid flowmeter includes an LSI digital device and an LSI analog device. The digital device drives a pair of acoustic transducers to transmit acoustic waves within a fluid, the flow of which is being measured. The a...
Flow Meter Abstract: A water meter and backflow preventer for use in a water supply system having a meter box includes a housing having water infeed and outfeed openings which are connected to supply water from a main utility pipeline to a water cust...
Flow Meter Abstract: A fluid velocity meter having an elongate body defining a flow opening therein bounded by an inner top wall, inner bottom wall, and a pair of side walls with the flow opening extending completely through the elongate body to allo...
Flow Meter Abstract: A piston flow meter for measuring the flow of a gaseous fluid, such as ambient air, through the flow meter by timing the displacement of a piston in a hollow precision bore flowtube over a fixed distance. The piston is reciprocat...
Flow Meter Abstract: A Karmans vortex flow meter eliminates the problem of external vibration resonating an amplifier casing to lower measurement accuracy of a vortex detecting section. In the flow meter, O-rings fit in two annular grooves formed on...
Flow Meter Abstract: A mass flow meter for a gas dispenser includes apparatus and method for determining specific heat ratio of the gas as a function of two pressure measurements in relation to a nozzle and for determining mass flow rate as a functio...
Flow Meter Abstract: An improved peak flow meter for measuring the peak flow of exhaled air including an indicator and one or a plurality of vents designed so that the indicator provides a logarithmic measurement of the exhaled air. Also provided is...
Flow Meter Abstract: A float mountable on a guide rod in a flow meter site tube including a non-metallic body having a generally cylindrical portion and a generally hemispherical portion. The hemispherical portion forms a leading end of the body oppo...
Flow Meter Abstract: An air-flow meter for milking machines, comprising an enclosed housing with a connection to a line that is to be tested for flow and pressure and with an air-intake mechanism with a variable cross-section. The air-intake mechanis...
Flow Meter Abstract: A flow meter for measuring a flow rate of fluid includes a body providing a main passage through which the fluid flows. A plurality of support elements connect an inner wall surface of the body and a central element so as to supp...
Flow Meter Abstract: An apparatus for determining the relative flows of a two phase flow using differential pressure to obtain mass flow having a bend portion for concentrating the dense phase toward an outside of the bend; a perforated plate downstr...
Flow Meter Abstract: A flow meter comprises a conduit adapted to conduct a flow of a fluid, a stop in the conduit, and a body that is movably received in the conduit, is normally kept in engagement with the stop by the fluid flow, and has at least a...
