22 Display fountain, system, array and wind detector US10537273 2003-11-26 US07735749B2 2010-06-15 John Tippetts
A fountain (50) comprises a supply of water under pressure, a primary fluidic diverter (10) having an input (12) for said supply, and first and second outputs (16a, b) diverging from said input. Two control ports (20a, b) are provided with control flow to direct input flow to one or other of the two outputs that lead to the two inputs of a vortex amplifier (40). This comprises a vortex chamber (54), a radial port (50), a vortex inducing port (60) and an axial output port (58). One (16a) of the diverter outputs is connected to the vortex inducing port, the other (16b) to the radial port, so that supply to said axial output port is modulated by formation of a vortex in the chamber when flow is to the vortex inducing port. The axial port leads to a nozzle whereby a vortex spray or axial jet is produced, depending on which diverter output (16a, b) is active. A wind detector (100) has a vertical jet (102) and a catcher (104) which fails to catch water from the jet in high wind conditions. The catcher feeds the control port (20a) of a diverter 101, or such other pressure or flow detector as may be convenient. A fountain array of elements may comprise a number of diverters, the outputs of which have branches supplying the control ports of others in the array, whereby internal control is provided.

The disclosed method of measuring the flow of a fluid with a porous particulate ceramic tracer and an optical instrument is characterized in that spherical particles having diameters in the range of 0.5 to 150 .mu.m are used as the tracer. Inasmuch as the tracer particles for flow measurement are spherical, the sectional area of scattered light to be detected by an optical sensor means is constant regardless of the orientation of particles. Furthermore, spherical particles have no surface irregularities that might cause concatenation so that individual particles are not agglomerated in tracking a fluid flow, thus contributing to improved measurement accuracy.
24 Method and apparatus for measuring flow-speed of gases US42663073 1973-12-12 US3875797A 1975-04-08 ZWENG JOSEF
A main stream of gas is advanced in the path, and an auxiliary stream of gas is directed across the path from one to an opposite side thereof where it impinges against a pair of separated apertures which are spaced from one another in the direction of elongation of the path. This creates differential pressures in the apertures since the auxiliary stream is deflected to some extent by the main stream and does not uniformly impinge upon both apertures. The differential pressures are measured and the auxiliary stream is moved longitudinally of the path until the pressures created in both of the apertures are identical. The extent to which the auxiliary stream has had to be moved in order to produce uniform pressure in both of the apertures is an indicator of the flow speed of the main stream.
25 Fluid flow measuring device US3785206D 1972-04-26 US3785206A 1974-01-15 BENSON J; BAKER W
Apparatus for measuring the velocity of fluid flow includes a form of pitot tube having orifices that develop a differential pressure related to the stream velocity and a means of directing an auxiliary stream of gas at or near one of the orifices. The auxiliary stream is arranged to be deflected by the main stream so that in the range of low velocities of the main stream, wherein pitot tubes are insensitive, the sensitivity of the apparatus is enhanced. In a preferred form of the device, a purged thermal flowmeter connected to the two orifices senses the velocity of the main stream.
26 Air momentum anemometer US3719079D 1971-04-05 US3719079A 1973-03-06 HOWELL W
A device for the measurement of horizontal wind velocity, especially low wind velocity. The horizontal component of momentum of the airstream is displaced from its normal flow. This is accomplished by either injecting an air jet into the airstream to displace the horizontal component of momentum, or withdrawing from the airstream the horizontal component of momentum by passing the airstream over an inlet into which inlet is drawn the horizontal component of the momentum flux of the airstream. The momentum of the air is converted to a force which is thus sensed and measured by a transducer, and since the force transduced is proportional to the first power of wind speed, large forces which may be accurately measured at low wind speeds are achieved.
27 Fluidic direction and velocity detection apparatus US3686937D 1970-06-10 US3686937A 1972-08-29 COREY VICTOR B
Fluidic detection apparatus for determining the direction and velocity of flow of an incident fluid flow stream. A jet stream producing means is disposed in axial spaced relation to a jet stream detector and initially disposed such that the common axis lies generally in the direction of flow of the incident fluid flow stream. Any deflection of the jet stream from its normal path, caused by the intersection therewith of the incident fluid flow stream, is detected by the jet stream detector and a servomechanism responsive thereto rotates the apparatus until the jet stream is aligned with the direction of the incident fluid flow stream. A second jet stream producing means and axially spaced jet stream detector are positioned 90* to the direction apparatus and are mounted for lateral translation by the servomechanism to detect the velocity of the same incident fluid flow stream.
28 Measuring system for a fluid flow stream US3677086D 1970-06-10 US3677086A 1972-07-18 COREY VICTOR B
An apparatus for determining a characteristic, as velocity or direction, of a fluid flow stream. Fluid sensors generate signals which are differentially compared to produce an error signal representative of the amount of movement, for the sensors or for a fluid stream generator, which is necessary to null the system. A servomechanism produces the nulling movement in response to the error signal. The amount of movement also generates a positional signal indicating the low frequency component or steady state characteristic of the fluid flow stream. A signal adder combines the positional signal with the error signal, containing a high frequency component, to provide an indication of the instantaneous fluid characteristic.
29 Flow sensor assembly US15291692 2016-10-12 US10072470B2 2018-09-11 Kim André Henriksen; Kenneth Torjussen

35 Apparatus for measuring the velocity of a fluid US437758 1974-01-28 US4026149A 1977-05-31 John W. Tanney
A fluid stream velocity measuring apparatus and its method of use wherein a fluid jet is directed from a nozzle along a portion of the flow path of a fluid stream whose velocity is to be measured, towards the open end of one or more receiver tubes. The nozzle and receiver tube or tubes are mounted by mounting means to have a jet forming space, extending between them a distance of at least five times the minimum distance across the nozzle orifice, with the fluid stream having a substantially unobstructed flow path along a surface of the mounting means extending past the nozzle and receiver tube or tubes. The fluid pressure in the receiver tube or tubes is measured to determine the velocity of the fluid stream into which the jet is directed. The internal geometry of the fluid jet nozzle is derived from the jet Reynolds number which is in excess of 1700 and the external geometry of the nozzle and/or receiver is defined to provide a substantially unobstructed flow path past the nozzle and receiver and substantially unrestrained interaction of the fluid stream with the jet.
36 Air momentum anemometer US31955172 1972-12-29 US3848465A 1974-11-19 HOWELL W
A device for the measurement of horizontal wind velocity, especially low wind velocity. The horizontal component of momentum of the airstream is displaced from its normal flow. This is accomplished by either injecting an air jet into the airstream to displace the horizontal component of momentum, or withdrawing from the airstream, over an inlet, into which inlet is drawn the horizontal component of the momentum of the airstream. The horizontal momentum flux of the air is converted to a horizontal force which is thus sensed and measured by a transducer, and since the force transduced is proportional to the first power of wind speed, large forces which may be accurately measured are achieved at low wind speeds. The force which is sensed and measured is converted to a pulsing variable superimposed on a null signal or on a signal of constant magnitude. The conversion of the pulsing or oscillating signal in this manner overcomes the problem of zero drift.
37 Device for measuring the rate of flow of dust-laden gases US29014772 1972-09-18 US3803911A 1974-04-16 SHKATOV E; ZHUKOV J; KOZLOV A

39 Optical flow speed sensor JP1290882 1982-01-28 JPS58129263A 1983-08-02 OOMAE YOSHINOBU; SHIMADA YOSHIO
PURPOSE:To measure the flow speed optically, quickly and accurately by simple signal processing in accordance with large random signals by running air foam out into fluid, and measuring the flow speed by the random signal of the light scattered by the air foam. CONSTITUTION:Air foam 5 is run out into the fluid of a flow pipe 7 by an air pump 12 and an air foam injecting pipe 14. A photosensor 1 provided with optical fibers 8, 9 for light projection and photodetection detects optically large random signals by the light scattered by the air foam 5. Thus, even with the fluid contg. less dust and suspended solids, the large random signals are detected easily, and the flow speed over a wide range is measured optically, quickly and accurately by the simple signal processing.
40 Measuring method for flow of ground water JP16549381 1981-10-16 JPS5866856A 1983-04-21 HINO TSUTOMU
PURPOSE:To make the properties of soil coincident with those of ground water strata and to measure the flow of the ground water with high accuracy by providing measuring electrodes and an electrolyte injecting pipe of double construction in an observing part, injecting pressure water, burying the observing part and detecting the flowing of an electroyte with the electrodes. CONSTITUTION:An electrolyte injecting pipe 12 and measuring electrodes 13-28 of double construction are provided in the observing part 11 of a probe 4 and are so designed as to deliver pressure water. The electrodes 13-28 consist of 8 sets of inside and outside electrodes which are disposed concentrically. In the stage of measurement, the probe 4 is brought downward and pressure water is injected near the holes of the bottoms whereby the part 11 is buried into ground water strata. Then an electrolyte is run from the pipe 12. When the electroyte arrives at the electrode group on account of flowing of the ground water, a change in the resistance value is detected with the change in voltage. The flowing direction is known from the electrode direction of the set by which the peak of said voltage is detected, and from the time when the same arrives at the electrode, the velocity of flow is detected. Therefore roughly the same flow as that of the ground water is obtained and the flow is measured with high accuracy.
