มิเตอร์วัดอัตราการไหลของก๊าซธรรมชาติมีกี่ประเภท?

Coriolis flow meter-Best accuracy natural gas flow meter

• ✔ Coriolis mass Flow Meters: Direct mass flow measurement of natural gas ,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,hence it can be used as custody transfer for natural gas .it can also measure high pressure natural gas flow rate.

Thermal mass flow meter

• ✔ 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.

Gas turbine flow meter

• ✔ Turbine Flow Meters: It is a kind of velocity type gas flow meter, 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.Gas turbine flowmeter measures natural gas flow, and has the characteristics of small pressure loss, high accuracy, wide flow range ratio, good anti-vibration and anti-pulsation performance. Commonly used  include 2” natural gas turbine flowmeter,  4 inch gas turbine flowmeter, etc.

Vortex flow meter

• ✔ 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.The internal sensor of the vortex flowmeter has no moving parts, simple structure, and stable flow coefficient of the instrument, so the natural gas flow measurement is reliable and the failure rate is low. The digital natural gas flowmeter can output digital pulse signal or current signal, and can have HART or MODBUS communication.

• ✔ Rotameters flowmeter or vairable area flow meter has a simple structure and is widely used in industrial flow measurement. This type of flowmeter has a long history and has appeared in the middle of the last century. The rotor flowmeter is mainly composed of a cone tube and a float. When the natural gas flows from bottom to top in the cone tube, when the naturla gas flows steadily, the float is stationary in the middle, and the flow rate of the fluid can be calculated from the position of the float.
