Benefits of technology
The present patent describes a system for measuring the gas flow in a housing. The system includes a device that modifies the flow of gas, a sensor that generates an electrical signal based on the flow characteristics, and a processor that analyzes the signal to determine the flow parameters of the gas. This technology can be used to accurately measure the gas flow from a source to a destination.
Problems solved by technology
However such gas metering systems are typically adversely impacted by gas density fluctuations, moisture fluctuations, gas mixture fluctuations, and the like.
Consequently, such gas metering systems fail to provide a direct and accurate volumetric flow rate measurement.
These factors adversely affect the quality and accuracy of flow measurement.
However, measurement of the flow rate using the vortex-based sensing devices is adversely impacted when a velocity of the gas is low as the low velocity of the gas affects formation of vortices.

Abstract
A system for metering gas is presented. The system includes a housing configured to allow a flow of the gas between an input port and an output port. Further, the system includes a flow manager disposed in the housing and configured to modify at least one physical characteristic of the flow of the gas in the housing. Furthermore, the system includes a flow sensor disposed in the housing and configured to generate an electrical signal in response to flow characteristics of the gas in the housing. Moreover, the system also includes a processor configured to determine at least one flow parameter of the gas based on an amplitude characteristic of the electrical signal, a temporal characteristic of the electrical signal, or both the amplitude characteristic and the temporal characteristic of the electrical signal. A method for metering the gas is also presented.
Description
BACKGROUND[0001]Embodiments of the present disclosure relate to measurement of a flow of fluids, and more particularly to a system and method for metering gas.[0002]Currently, metering of gas entails use of various types of flow sensing devices such as mass flow sensing devices to measure a mass flow rate of fluids. Some flow sensors determine the mass flow rate of the gas based on an amplitude measurement. Other flow sensing devices involve vortex-based sensing where, for example, a frequency at which vortices are formed is essentially proportional to the flow rate of the fluid. Consequently, the volumetric flow rate is determined based on the frequency at which the vortices are formed.[0003]Generally, the currently available gas metering systems offer the advantage of high sensitivity in a low flow range. However such gas metering systems are typically adversely impacted by gas density fluctuations, moisture fluctuations, gas mixture fluctuations, and the like. Consequently, such ...
