| Disclosed are apparatus and methodology for measuring gas flow. A gas flow meter can include a plurality of sensors to detect a gas flow at various flow rates in the meter. A first sensor can detect a gas flow at a low flow rate and a second sensor can detect a gas flow when the flow rate is sufficient to produce an oscillating jet. The first sensor can be disposed parallel to the gas flow and detect the flow rate and the temperature of the gas flow. When the flow rate of the gas is below a predetermined threshold, power is supplied to the first sensor to detect gas flow. When the gas flow rate is high enough such that the gas flow produces an oscillating jet of fluid, power is supplied to the second sensor. The second sensor can detect the frequency of the oscillating jet flow. | ||||||

| The present invention relates to a magnetic flow controller which transforms a slow reduction in pressure of fluid flow over time to a measurable fluid flow. Once a threshold pressure differential is reached, a flow passage through the flow controller opens rapidly to a relatively large opening, thereby generating a volume of fluid at high flux flowing through the passage, particularly to permit the measurement of the volume of fluid in a conventional flow meter. The device of the present invention integrates this low flux and transforms it to a measurable fluid flux, so that the fluid can be measured by the fluid meter within its optimum error range. This is accomplished while maintaining a pressure drop in the flow meter which is within the permitted standards. Thus, the invention provides relatively sharp shifts between substantially high flux flow and no flow, in a pulse-like manner. | ||||||

| A device is provided for measuring the velocity of flow of a fluid in a respiration system and includes a first thermal sensor element (5) provided with a controllable heating element (50) and a second thermal sensor element (6). The thermal sensor elements (5, 6) are arranged at spaced locations from one another at a path of flow, so that a thermal signal generated by the first sensor element (5) with the heating element (50) is transmitted to the second sensor element (6), and the second sensor element (6) is designed to detect the thermal signal from the fluid flow. The second sensor element (6) is connected to the first sensor element (5) via feedback (12) which triggers another thermal signal. A controlling and analyzing device (13, 15) is connected to the sensor elements (5, 6) to start the generation of a first thermal signal and to read and analyze the signal frequency as an indicator of the velocity of flow. | ||||||

| A flow responsive valve for a flow metering system comprising a fluid meter having a minimum measuring flow threshold. The valve is shiftable between an open position at flow rates above the minimum measuring flow threshold, and a pressure pulsating position depending on pressure differential over an inlet port and an outlet port of the valve. The pressure pulsating position alters between a closed position essentially prohibiting fluid flow therethrough at flow rates below the minimum measuring flow threshold, and an open position admitting fluid flow into the supply line at a measurable flow rate above the minimum measuring flow threshold. | ||||||

| The flow of a fluid at low flow rates is measured in a flow sensing assembly and controlled without introducing measuring devices into the fluid flow path. The flow sensing assembly is enclosed in a housing to lessen ambient and fluid temperature change effects on the measurements obtained. As the fluid is flowing through tubing in the flow sensing assembly, the tubing is heated to impart heat to the fluid. Heat sensors are attached at spaced positions from each other along the tubing in the direction of fluid flow to sense temperatures. The amount of heat applied to the tubing is controlled to maintain an established temperature differential between the heat sensors. The amount of heat applied is measured to provide an accurate and proportional indication of the fluid flow rate. | ||||||

| A turbine wheel flow measuring transducer is provided for measuring low flow rates of corrosive fluids, whether fluids or gases. The transducer has a turbine wheel rotating in a housing fluid chamber at a rate set by the corrosive fluid flowing through the housing. Infrared light from an optical flow measurement circuit passes through spaced holes in the rotating turbine wheel. The amount of light which passes through the wheel indicates flow rate. The housing is made from a corrosion resistant synthetic resin which is also translucent to infrared light from the light source. The light source thus need not be in the housing fluid chamber, materially simplifying the transducer. Further, the turbine wheel is provided with an improved bearing support so that problems of thermal expansion of the housing are overcome. | ||||||

| A method of, and apparatus for, measuring flow rates of highly viscous source fluids, having a flow rate wherein a secondary fluid of the same viscosity is injected at a predetermined measurable rate of flow into the stream of source fluid, where the source and secondary fluids are intermixed.
