| 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. | ||||||

| A thermal flow sensor is responsive only to a modulated component of the flow. At zero flow the modulated component disappears, except for an artifact caused by motion of the modulator. This artifact is minimized by reducing the extent of modulator motion and by sampling the modulated signal at a quiescent part of the modulator's operating cycle. This results in a thermal flow sensor with a very stable zero. | ||||||

| 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. | ||||||

| 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. | ||||||

| Low volume flow measurement apparatus developed for hearing dysfunction diagnosis but also suited to other applications comprises means (10) defining a cavity operably communicable with the variable volume, a D.C. microphone (15) responsive to ambient pressure changes in the cavity due to variations in said volume, and a reference diaphragm (17) operably connected with the cavity and moveable under servo-control responsive to the microphone to maintain the cavity pressure constant. The cavity will normally have a vent valve (18) and in non-hearing application may be coupled with the subject volume by a plunger seal. For hearing diagnosis the apparatus is suitably carried by a helmet (21) or harness with a headphone on the opposite side for sound stimulus application, the helmet itself being at one end of a boom (22) with a counterweight (23). | ||||||

| A method of measuring the instantaneous volumetric flow rate of an intermittent or pulsating fluid flow comprises the steps of employing a flow meter unsuitable for measuring flow rates below a given threshold value, adding to the intermittent fluid flow to be measured a second fluid flow having a known flow rate exceeding the threshold value of the flow meter, supplying the resulting combined fluid flow to the flow meter and subtracting from the measuring output of the flow meter a value corresponding to the known flow rate of said second fluid flow, whereby a measuring output is produced representing the instantaneous volumetric flow rate of the unknown intermittent fluid flow.
