In-line flow meters which suitable for natural gas flow metering include gas turbines flow meter, vortex flow meters and thermal dispersion flow meter. These in-line natural gas flow meters all have electronic display that shows natural gas instantaneous flow and cumulative flow .In-line natural gas flow meters are also divided into volumetric flow meters and mass flow meters.Silver Automation Instruments sell low price digital natural gas flowmeter with fast lead time and rugged quality.Natural gas is a kind of fuel gas, the main component of natural gas is CH4 (methane), which is colorless, odorless, non-toxic and non-corrosive. It also includes certain amounts of ethane, propane and heavy hydrocarbons, as well as small amounts of nitrogen, oxygen, carbon dioxide and vulcanization. Natural gas ignites to produce H2O (water).
In-line gas turbine flow meter for natural gas volumetric flow measurement
When the natural gas flows through the turbine flow sensor, the turbine is forced to rotate under the action of the fluid thrust, and its rotation speed is proportional to the average flow velocity of the natural gas. The rotation of the turbine periodically changes the magnetic resistance value of the magnetoelectric converter, and the magnetic flux in the detection coil is followed. A periodic change occurs, producing a periodic electrical pulse signal. The electrical pulse signal is proportional to the volumetric flow of fluid flowing through the turbine flow sensor over a range of flow rates (Reynolds numbers).

Vortex shedding flow meter for fuel gas flow rate measurement
A non-streamlined vortex generator is placed in the fluid, and the fluid is alternately separated on both sides of the vortex generator to release two rows of regularly arranged vortex . Within a certain flow (Reynolds number), the separation frequency of the vortex is proportional to the volumetric flow of the fluid flowing through the vortex flow sensor.
