air dispenser

Equipment used for filling CNG or LNG into gas storage cylinders of gas vehicles, equipped with metering and pricing devices.

The responsibilities of metrological management personnel should include at least the following:

Implement measurement laws, regulations, policies, and gas station measurement management systems;

Establish and manage a ledger of measuring instruments and measurement management files;

Responsible for the management of the equipment, use, and maintenance of measuring instruments;

Responsible for the calibration and verification of measuring instruments

Timely inspect newly added, replaced, and repaired measuring instruments, and repair or scrap inaccurate measuring instruments;

Responsible for risk management of measuring instruments;

Responsible for the management of natural gas inventory measurement within the station.

Responsible for handling measurement complaints.

Equipping measuring instruments

Gas stations should be equipped with measuring instruments in a scientific and reasonable manner in accordance with the measurement management requirements of this standard to meet the needs of measurement work.

The equipment of measuring instruments should include at least the following contents (according to the requirements of different types of gas stations):

CNG dispenser;

CNG loading/unloading column;

LNG dispenser;

Combustible gas detection alarm;

Temperature instrument;

Pressure gauge;

Liquid level meter;

Flowmeter.

Gas station * natural gas analysis gas chromatograph

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 20 minutes.

This machine integrates an analysis column, detector, working software, and computer. Convenient to carry, suitable for both online pipeline inspection in industrial sites and airbag sampling analysis in laboratories;

● 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, etc;

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

Can be equipped with a mouse and printer;

Gas detection parameters:

1. Carrier gas: high-purity hydrogen gas (purity ≥ 99.995%)

2. The built-in calorific value software automatically calculates the component content, high calorific value, low calorific value, density, relative density, Hua Bai number, and combustion potential

3. TCD sensitivity S ≥ 3000mv. ml/mg (benzene) noise ≤ 0.02mv

4. Air intake requirements: dust-free, waterless, oil-free

7. Built in injection valve: automatic injection, automatic reset (module control)

8. Qualitative time error: ≤ 0.02min

9. Detection *. 1%

11. Instrument size: 370mm × 290mm × 20mm (length * style * height)

12. Working environment: -10 ℃ -60 ℃: Humidity: 10% -85%

13. Input power supply: AC220V

14. Whole machine weight: 7KG (approximately)
