Introduction

Commonly used natural gas flowmeters include gas turbine flowmeter、gas roots flowmeter、precession vortex flowmeter.，As a clean energy, natural gas occupies an important position in China's energy strategy, and other flowmeters are not recommended for various reasons.

Natural gas measurement conditions and customer requirements are different, choosing the right natural gas flow meter has become a difficult problem. Shanghai Aister Instrument focuses on gas flow meter production, sales, research and development as one of the technical enterprises, can provide customers with natural gas flow measurement solutions and professional selection.

Aister's staff take “only choose the right one, not the expensive one”as the purpose, and choose the type and quotation for customers.

Features

Gas turbine flowmeter measurement of natural gas advantages: gas turbine flowmeter measurement of natural gas in the accuracy, repeatability, zero drift, range ratio and other aspects have obvious advantages, its bearing production, guide plate through special design, can reduce wear, to ensure the reliability of measurement under special conditions; Its output signal is pulse, easy to digitize.

Precession vortex flowmeter measurement of natural gas advantages: because the precession vortex flowmeter measurement of natural gas dynamic display is different from other steam flowmeters, liquid crystal display, display information total flow, working pressure, temperature integrated together is its outstanding advantages, precession vortex flowmeter is a high-precision total flow detection instrument.

Gas waist wheel (Roots) flowmeter measurement of natural gas advantages: gas waist flowmeter is also known as Roots flowmeter, it can be used to measure the flow of dry gas, can also be used to measure the flow of associated gas. Orifice flowmeters and turbine flowmeters are not suitable for measuring associated gas containing droplets.

Other flowmeter features Other flowmeters: vortex flowmeter, orifice plate, metal rotor flowmeter, thermal gas mass flowmeter (for various reasons, it is not recommended to apply these four flowmeters)

Natural gas flow meter selection: More than 20 years of experience in the instrument and meter industry engineers, providing gas flow measurement solutions and professional selection.
