The LNG detectorEquipment Introduction

Chuanhao Instrument is not a mirage. Whether in enterprises or institutions, or in units and manufacturers that are using or need to use natural gas, our company's products can always be seen. Independently analyze the high and low calorific values and gasification rate of LNGCNG. It is a product that is at the forefront of technology and can help us monitor changes in production while providing friendly services and technology.

Chuanhao brand instrument LNG and CNG dedicated calorific value analyzer. As an established chromatograph manufacturer, we have always followed the traditional technology foundation and continuously injected fresh energy into our equipment. Traditionally speaking, gas chromatography, as a relatively stable device, can ensure the stability and reliability of data output and can be used for a long time. On top of these foundations, the company has now updated its equipment with a user-friendly interface that saves manpower and time in automatic data collection and processing.

LNGCNG, as a major combustible gas, has some parameters that are important in production or auxiliary production, and the quality of the gas is a crucial factor. As a common supply, the calorific value and nitrogen content of LNG are the main detection objects, and its gasification rate is also a highlight of attention. To solve these contradictions, Chuanhao Instrument adopts a dual detection method, which can not only meet the requirements of gas composition analysis, but also meet the detection of gas combustion efficiency, high calorific value and low calorific value. Of course, gasification rate is also an important indicator.

The LNG detectorEquipment configuration plan
