Natural gas calorific value analyzer

Natural gas calorific value analyzerThe calculation method for gas calorific value is based on the following standards:

GB/T13610-2014 "Composition Analysis of Natural Gas - Gas Chromatography Method"

GB/T 12206-2006 "Determination of Heating Value and Relative Density of Urban Gas"

GB/T11062-1998 "Calculation method for calorific value, density, average density and Wopo index of natural gas"

Product Features:
The instrument has a stylish appearance and beautiful design; 12 inch display screen, displaying rich and intuitive content; Small in size, light in weight, and easy to carry, it is suitable for laboratory testing and analysis of LNG users, as well as for gas companies to carry instruments to multiple user points for testing. The operation of this instrument is very simple, even personnel who have not been in contact with this instrument can learn it at once. Insert the gas sampling bag into the 'sample inlet' of the instrument, and press the 'start' button to automatically run the instrument (automatic sampling, automatic analysis, automatic signal collection, no need for manual intervention). Automatically calculate the detection results within 10 minutes.

Natural gas calorific value analyzerPerformance advantages:

The fully automatic one click start system (automatic sampling, automatic collection, automatic display of analysis results, no need for manual intervention) is easy to operate;

The instrument automatically adds bridge current when turned on, without the need for manual bridge current operation;

The all-in-one machine (chromatographic column, detector, dedicated calorific value working software, computer, chromatographic gas source hydrogen generator) is easy to carry and suitable for both online pipeline detection in industrial sites and laboratory airbag sampling and analysis;

● Integrated sealed heating, with low heat dissipation ratio, higher efficiency, and energy savings;

● Dual channel calorific value working software, automatically calculates the detected gas component content, high calorific value, low calorific value, density, relative density, Huabai number, combustion potential, gasification rate, etc;

The calculation results of the working software are based on the values of calorific value, density, gasification rate, etc. under national standard conditions;

Built in automatic sampling pump and electric injection valve to improve the repeatability of detection results;

Gas detection components: nitrogen, oxygen, carbon dioxide, methane, ethane, propane, butane and other components;

The instrument can have a built-in printer (optional);

Standard Modbus RTU transmission protocol can be used according to user needs;

The built-in generator is equipped with a non backflow device, which can effectively ensure that the instrument has no backflow phenomenon. Integrated liquid storage, electrolytic hydrogen production, and oxygen discharge, with low pool temperature and long lifespan.
