| A measuring device is disclosed for measuring an ultra low gas flow, working by the principle of liquid displacement. In at least one embodiment, the measuring device includes at least one cell including a gas inflow device, a gas compartment device with a predefined inner geometric physical volume and active volume. In at least one embodiment, the gas compartment device includes one gas accumulating end and one lifting end, the gas compartment device also defining a geometric gas collecting point inside of the gas compartment device, during a gas filling cycle, the geometric gas collecting point moving further and further from the gas accumulating end to the lifting end during the gas filling cycle. Further, in at least one embodiment the cell includes a holding device having a pivoting element enabling the gas compartment device to pivot upwards when the geometric gas collecting point is positioned at the lifting end and the lifting force is larger than the down-pressing force at the lifting end, thereby releasing all of the accumulated gas in the gas compartment device, and then pivoting back to its initial standby position for new receipt and storage of gas during another gas filling cycle until next releasing sequence. Finally, in at least one embodiment, the cell also includes a sensor provided to generate a signal and/or change the state of a signal when the gas compartment device is not in its initial standby position, wherein the gas storing capacity of the inside of the gas compartment device is larger at the gas accumulating end than at the lifting end and wherein the gas accumulating end has a higher vertical position than the lifting end at the initial standby position. | ||||||

| Methods and systems are described that provide for measuring flow properties of multiphase mixtures within a pipe carrying gas-liquid hydrocarbons and water produced from oil-gas wells. The methods and systems may provide for a combination of a clamp-on ultrasonic gas flow meter to measure flow characteristics of a gas phase in a pipeline and a pulsed ultrasonic Doppler sensor(s) and/or an RF/microwave electromagnetic sensor(s) to measure flow characteristics of a liquid phase. The combination of sensors may provide for multiphase flow measurements under certain flow conditions, such as when the gas-liquid is flowing in a substantially horizontal pipeline, when the flow is stratified or is caused to be stratified and/or the like. | ||||||

| A fluid flow metering device and a method thereof are provided. The fluid flow metering device includes a fluid flow detector, a memory, a micro controller and a power generator. The fluid flow detector is disposed in a supply tube of a fluid flow provider. When the fluid flows in the supply tube, the power generator generates a supplying power through flow of the fluid, and provides the supplying power to the fluid flow detector, the memory and the micro controller. When the fluid flow detector detects the flow of the fluid, the fluid flow detector detects the flow of the fluid outputted from the supply tube to derive a detecting value. The micro controller receives the detecting value and writes the detecting value into the memory, or the micro controller converts the detecting value into a flow value and writes the flow value into the memory. | ||||||

| A wet gas flow measuring method, wherein measuring total flow differential pressure value ΔP of wet gas in a pipeline by a differential pressure flow measuring device (201), measuring section gas contents of the wet gas in the pipeline by at least two phase fraction meters respectively (202), obtaining optimized section gas content value GVFopt by a flow calculating module based on the section gas contents respectively measured by the at least two phase fraction meters (203); and calculating gas volume flow rate Qg and liquid volume flow rate Ql by the flow calculating module based on the total flow differential pressure value ΔP of the wet gas and the optimized section gas content value GVFopt (204). As the section gas content of the wet gas in the pipeline is detected by the redundant phase fraction meters, the gas volume flow rate Qg and the liquid volume flow rate Ql can be measured accurately, which meets the requirements on production measurements of oil and gas field and facilitates management improvement and production optimization of oil-gas reservoir. A wet gas flow measuring apparatus is also provided. | ||||||
