To start the flow, they drill inside these rocks, which will make the fluid easier to extract. The capacity of the discovered reservoirs can be determined by their porosity, while the production capacity is proportional to their permeability. The main reason for this is that these materials move easily through the rock, making them easier to accumulate. For the most part, natural gas and oil fields exist on sedimentary rocks such as sandstone and limestone. We work with you to improve process efficiency, reduce costly production downtime, and establish real-time monitoring and control.īefore discussing the different flow meters commonly used in the oil and gas industry, it is important to first understand the process of how the industry collects raw materials.īoth of these raw materials exist in different geological sources. We work with many of our upstream and downstream customers to develop custom flow solutions for their toughest challenges, handling the most demanding chemicals in their most remote and hazardous areas. Difficult oil and gas flow metering challenges such as high pressures, pulsating flows, corrosive media and harsh environments are our daily business. Gases, liquids and fluids are measured based on mass flow and volume flow.įrom corrosive subsea environments, offshore production platforms, onshore oil fields or refineries, we have the flow expertise to tackle these tough jobs. Such applications define the capacity and type of flow meters. These flow meters are used by industry (especially gas and oil) to calculate the mass flow or volume flow of fluids. Thanks to their hard work, the creation of different flow meters was possible and because of this, the oil and gas industry is still strong today. From extraction to delivery of these raw materials, everyone in the business has invested a great deal of effort to obtain the most accurate measurements.Īs a result, scientists and engineers have been working hard to find new methods and techniques to make more efficient metrology systems. It is widely used in heavy industrial applications, power facilities, and energy industries, particularly in steam processes.For years, people involved in the oil and gas industry have been innovating and creating ways to get accurate measurements. The vortex flowmeter is relatively economical because of its simple flow measurement system and ease of maintenance. The vortex flowmeter is a broad-spectrum flow meter which can be used for metering, measurement and control of most steam, gas and liquid flow for a very unique medium versatility, high stability and high reliability with no moving parts, simple structure and low failure rate. In certain range of Reynolds number (2×10^4~7×10^6), the relationship among vortex releasing frequency, fluid velocity, and vortex generator facing flow surface width can be expressed by the following equation: į = S t × V d is the width of the triangular cylinder. The signal is sent to the intelligent flow totalizer to be processed after being amplified by the pre-amplifier. The frequency of these pulses is directly proportional to flow rate. The piezoelectric element encapsulated in the detection probe body generates an alternating charge signal with the same frequency as the vortex, under the action of alternating stress. Since both sides of the vortex generator alternately generate the vortex, the pressure pulsation is generated on both sides of the generator, which makes the detector produce alternating stress. When the medium flows through the Bluff body at a certain speed, an alternately arranged vortex belt is generated behind the sides of the Bluff body, called the " von Kármán vortex". Composition of vortex flowmeter Ī vortex flowmeter comprising: a flow sensor operable to sense pressure variations due to vortex-shedding of a fluid in a passage and to convert the pressure variations to a flow sensor signal, in the form of an electrical signal and a signal processor operable to receive the flow sensor signal and to generate an output signal corresponding to the pressure variations due to vortex-shedding of the fluid in the passage. Vortex flowmeter is a flowmeter for measuring fluid flow rates in an enclosed conduit.
