Why need natural gas flow measurement in industry?
Natural gas refers to a combustible gas mixture with hydrocarbons as the main component extracted from nature. Natural gas is mainly composed of a mixture of gaseous low-molecular hydrocarbons and non-hydrocarbon gases. It is mainly composed of methane (85%) and a small amount of ethane (9%), propane (3%), nitrogen (2%) and butane (1%). Mainly used as fuel, but also used to produce raw materials for chemicals such as acetaldehyde, acetylene, ammonia, carbon black, ethanol, formaldehyde, hydrocarbon fuels, hydrogenated oil, methanol, nitric acid, synthesis gas and vinyl chloride. Natural gas is compressed into liquid for storage and transportation. We need natural gas flow metering device in coal mining, nitric acid plants, power plants, organic chemical synthesis plants, petroleum refining plants, etc.
Always remember that to get an accurate measurement, having the correct technology is critical. Here are the things you should consider when choosing a flowmeter for natural gas. Industrial Natural gas flow meter can be used in monitoring incoming gas to a gas burner,boiler,ovens, furnaces.,etc
How to choose natural gas flow meters ?
It is essential to understand the application of flowmeter technology before you choose one natural gas flow measurement device. Recently we posted some tips to keep in mind when picking the correct gas flow meter. Understanding is central to making the right decision.
#1 What purpose
will it serve? Are you picking meters for submetering, industrial gas
processing, custody transfer, or monitoring? Is it a volumetric natural gas
flow meter or mass flow meter you need? How much cost you will spend on
the natural gas flow meter? Do you need inline natural gas flow meter?Or
insertion natural gas flow meter?
#2 What type of
gas is it measuring? Is it a mixture of gases or a single gas? What is the flow
range, process temperature, accuracy required, and pressure? Will the gas be
clean and dry. Or dirty, corrosive, and wet.
#3 Where is the
intended installation? What conditions is it going to work under? Extreme
temperatures? Will it have enough straight run? What regulations must it meet,
if any? Are vibrations or noise a concern?
#4 What do you
need it to do? Do you need a local or gas flow totalizer display? What
calibrations do you need? Will advance electronics or upgrades be required? Do
you need natural gas flow meter totalizer? Will you need it maintained? Do
you need digital natural gas flow meter ?
Once you have
gathered all this information, you can now make a more educated decision when
choosing the correct gas flow sensor.

flow meters for natural gas measurement
Natural gas flow meter types
Following your review of the selection
guide, it is likely that you have narrowed the field to a few meters that might
suit your purpose. Now you should list the advantages and disadvantages of each
to make a more educated decision based on their operating principles.
✔ Thermal Mass Flow Meters: These meters rely on the principle that the rate of heat transfer is proportional to the mass flow rate of gas. They consist of a heated element and one or more temperature sensors. By measuring the temperature difference between the heated element and the gas, the flow rate can be determined. Thermal mass flow meter to measure natural gas has below flow units: SCFM, kg/h,g/s,g/min,NL/h, mmscfd, Sm3/h,Nm3/h, it has insertion type natural gas flow meter and inline type natural gas flow meters. The flow meter price can be very low for large natural gas pipeline.
✔ Coriolis Flow Meters: Coriolis flow meters utilize the Coriolis effect, which is the deflection of moving fluid due to the rotation of the Earth. These meters have a vibrating tube through which the gas flows. The gas motion causes the tube to twist, and the degree of twisting is proportional to the mass flow rate.Coriolis flow meter is the best natural gas flow meter, it can directly measure natural gas mass flow , and has the best accuracy for natural gas flow measurement.it can also measure high pressure natural gas flow rate.
✔ Turbine Flow Meters: These meters utilize a turbine rotor placed in the gas stream. As the gas flows through the meter, it causes the rotor to spin, and the rate of rotation is proportional to the flow rate. This rotational motion is converted into an electrical signal, which is then used to calculate the flow rate.
✔ Vortex Shedding Flow Meters: Vortex flow meters operate based on the principle that when gas flows past an obstacle (such as a bluff body), vortices or swirling patterns are shed alternately on each side of the obstacle. These vortices are detected and counted, and the frequency of vortex shedding is used to determine the flow rate.
✔ Orifice Plate Flow Meters: An orifice plate is a thin plate with a hole (or orifice) in the center. When gas flows through the orifice, it creates a pressure drop, which can be correlated to the flow rate. This pressure drop is measured using pressure sensors located before and after the orifice plate.

Industry natural gas flow meter price
The price of industrial natural gas flow meters is determined by many factors. Customers can choose the right industrial natural gas flow meter according to their field application and budget. Our price for natural gas flow meter starts from $ 500. Send email to us email@example.com
to obtain your industrial natural gas flow meter price cost.
☪ Natural gas flowmeter size: Generally, the larger the gas sensor size, the higher the price. For example, the price of a 4" natural gas flowmeter cost more than 1" natural gas flowmeter.
☪ Natural gas flowmeter measurement principle: different measurement principles, different prices. We can provide DP flow meters (differential pressure flow meter ), V cone flow meters for natural gas, orifice flow meters, Coriolis mass flow meters, thermal gas flow meters to measure natural gas, and turbine flow meters to measure natural gas volumetric flow rate. Pity is that SILVER does not sell natural gas flow meter ultrasonic principle or portable natural gas flow meter.
