CNG Gas Flow Meter Types | Coriolis Flow Meter


CNG Gas Flow Measurement

Silver Automation Instruments often talks about gas flow meters; we often recommend thermal mass flow meter, gas turbine flow meters, vortex flow meters and so on. Our gas flow meters serve many applications, but when referring to high pressure gas flow meters, such CNG gas flow meters, we usually recommend Coriolis mass flow meters.

What is CNG and LNG?

CNG (Compressed Natural Gas), a compressed natural gas, is natural gas pressurized (over 3,600 psi) and stored in a gaseous state in a container.

LNG (Liquefied Natural Gas), the abbreviation of LNG. LNG is condensed into a liquid by cooling it to -162 ° C in a gaseous natural gas at atmospheric pressure. Natural gas liquefaction can greatly save storage and transportation space and cost, and has the characteristics of large heat value and high performance.

Coriolis Mass Flow meter for CNG Gas Measurement

It is the trend that many process factories now replacing the traditional V-cone, Orifice plate flow meters with Coriolis flow meters due to its obviously Metris, such as high accuracy ,low maintenance, multi-parameters measurement and so on. Coriolis meter can measure liquid, gas and steam, it is good choice for large density or high pressure gas flow measurement, as we all know in CNG Gas Station, pressure is always high, such as 340 barg or even higher , in that case , High pressure Coriolis Flow meter is a ideal choice, see below SH-CMF series Coriolis Mass Flow meter Flow range and corresponding max pressure we can make:

Advantages for Coriolis Flow meters

High Accuracy: ±0.2%~±0.1% flow, so it can be used for custody transfer purpose

Direct measure Gas Mass Flow, not need external temperature and pressure compensation

No Moving parts in the flow meter sensor, so little maintenance and attention needed after mounting.

No strict straight pipelines requirement before and after the flow meter sensor

Multi-Parameters measurement, such as gas mass flow, gas volumetric flow, density, temperature by only one flow meter

Can be used to measure high viscosity liquid flow

Coriolis Flow meter Limitations

Not good for gas measurement in low pressure and low density

Flow measurement is sensitive to vibration

Max size Silver Automation Instruments can make is 200mm, 8 inch coriolis meter

The price is extremely high comparing to other types gas flow measurement devices
