41 Pick-up for the measurement of the velocity of an ionization gas US193298 1980-10-02 US4381679A 1983-05-03 Claude Lombard
A pick-up for measuring the velocity of a gas by ion transit time including a coupling positioned between a valve for the gas, the velocity of which is to be measured and an electrode serving to measure the transit time inside a conduit delimiting the gaseous discharge. This pick-up can be used to measure the velocity of discharge gases at the intake of the cylinders of an internal combustion motor.
42 Measurement of relative velocities US785 1979-01-03 US4248085A 1981-02-03 John Coulthard
An apparatus and method for measuring the velocity of a relative movement between first and second bodies or between a first body and a fluid. The first body may be stationary and the second body a moving body, such as hot strip steel. Alternatively, the first body may be an aircraft or ship whose velocity is to be measured or it may be a pipe or duct along which a fluid is flowing. At least two detectors are mounted on the first body and serve to detect noise signals representing disturbances in the fluid or on the second body. Correlating means generate data for producing at least two correlation or autocorrelation curves from the signals from the detectors. The data from the correlating means is then combined to enable production of a combined cross-correlation or auto-correlation curve, from which the relative velocity can be computed.
43 Ultrasonic anemometer US848232 1977-11-03 US4174630A 1979-11-20 Jacques A. G. Nicoli
An ultrasonic anemometer wherein there is a fixed supporting framework, transmitter-receiver piezoelectric transducers spaced a predetermined distance apart and making known angles between them, a generator of ultrasonic waves to excite said transmitters, each receiver being connected to an impedance matching circuit, a phasemeter and display means, the phasemeters relating to the various receivers being connected to a computer.
44 Correlators US555250 1975-03-04 US4019038A 1977-04-19 Donald Louis Critten; Peter Alan Johnson
The speed of flow of a fluid is measured by transmitting across the flowing fluid upstream and downstream ultrasonic energy beams, transmitted beams, deriving electrical outputs therefrom, detecting the outputs to provide upstream and downstream detected signals representing noise imparted to the transmitted radiant energy beams by the flowing fluid, digitizing the detected signals, and imposing a time delay or delays on the upstream signal corresponding to the time delay between the upstream and downstream signals due to the spacing of the receiver means. A shift register imposes the time delay or delays and the transmission time of the shift register is controlled in response to the product of the signals.
45 Velocity measurement system with synchronized demodulation US34974273 1973-04-10 US3858446A 1975-01-07 FLEMONS RALPH SEYMOUR
A system such as a flow velocity measuring system relies upon obtaining a signal having a slight phase difference from a carrier signal, due to a change in signal circuit characteristic. The disclosed arrangement provides highly sensitive detection of such slight phase differences, including the provision of signal components in mutual quadrature relation permitting selection and switching as a useful output signal of that component having an instantaneous value and polarity to meet a predetermined condition of positive-going value for a selected sense of phase change, in a leading or in a lagging sense. The system may be selected to be substantially insensitive to changes in carrier frequency, or to be amplitude insensitive.
46 Tag-sensing flowmeters US35778973 1973-05-07 US3813939A 1974-06-04 HEAD V
A tag-sensing flowmeter for fluids whice contain spatiallydistributed random tags in the form of triboelectric charges, or in any other form that can be detected to produce a corresponding electric signal. The fluid is conducted through a passage having two tag-sensing stations separated by a known distance. The two signals produced at these stations are amplified and algebraically combined to yield a difference signal which is applied to an auto-correlator to ascertain the transit time of the tags between the two stations, thereby to determine the flowrate of the fluid.
47 Ultrasonic velocity and mass flowmeter US19495771 1971-11-02 US3807228A 1974-04-30 MATZUK T
A system for measuring the velocity of a flowing stream in a hostile environment, such as at high pressure and high temperature, by focusing acoustical energy through the conduit to a location within the stream to thereby remotely create ''''hot spots'''' which function as tracers. The travel time of the ''''hot spots'''' from a tracer production station to a detection station is used to find velocity. Means to make a focusing traverse to aid in mass flow determination is also provided.
48 Apparatus for measuring the flow velocity of fluid within a conduit US3789663D 1972-05-11 US3789663A 1974-02-05 GOLD S
Apparatus for measuring the flow velocity of fluid within a conduit. Sensing means external to the conduit and responsive to changes in the configuration of the conduit surface upon passage of a vortex and associated with electrical means measure the time interval during which the detectable property of the fluid passes between a plurality of preselected locations on the conduit. Fluid flow is not obstructed by installation of the sensing means. Thus, flow measurements, at a plurality of locations along the conduit can be economically obtained.
