Methane gas analyser
Let's consider all the features of this equipment, starting with the definition. In general, a gas analyser for measuring hydrocarbons is a device that determines and begins to continuously record the volume fraction of vapours of organic compounds in the working environment. As soon as the concentration of the monitored component reaches a threshold value, the device warns about it by means of indication means (gives an audible and/or light signal).
Accordingly, the portable methane gas analyser determines the volume fraction of CH4. Here and below we will talk about the mobile version of this device, simply because today it is used much more often. Stationary models are much larger and are used at one particular site, usually an industrial site located in a hazardous area.
Use of portable methane gas analysers
Theoretically, they are relevant for any enclosed site where the air composition can change dangerously. In practice, a portable gas analyser for measuring hydrocarbons (methane in particular) is used at the following sites:
- basements, wells, sewage tunnels, other underground premises;
- food, pulp and paper, defence industries;
- water supply and waste disposal facilities;
- gas and oil production, transportation, processing lines;
- chemical and metallurgical plants, energy sector enterprises, medium-sized machine building.
Portable methane gas analysers are used by employees of housing and utility companies, petrol stations and gas stations. These devices help to detect and prevent CH4 vapour leaks in time and thus ensure human safety.
Important operating parameters
The key characteristics that determine the class and usability depend largely on the design and equipment. For example, quality portable gas analysers for measuring hydrocarbons (methane and other gases) are supplied with the following items:
- cables (power supply, null-modem);
- tachometer sensors;
- intake hoses and probes;
- spare filters and tubes;
- passport, software, calibration manual.
The modern instrumentation market offers dozens of series and hundreds of models of gas analysers for hydrocarbon measurements, with a wide variety of operating parameters. It is not possible to list and consider specific technical characteristics of each device - there are too many of them. And the equipment is very different from each other in terms of form factor and even interface. Hence, the question arises: what to focus on?
Key technical characteristics of the portable methane gas analyser:
- class - must comply with current GOST standards;
- measurement range - the wider it is, the better;
- allowable error limits, absolute and relative - the smaller they are, the more accurate the instrument is;
- service life and MTBF - the higher these values, the more durable the equipment;
- weight and dimensions (DxWxH) - the more compact the portable methane gas analyser is, the better (if it does not compromise the convenience of measurements);
- additional functions - condensate auto-drain, excess air temperature calculation, auto-zero adjustment and so on - the more such options, the wider the scope of application.
Performance features, practical advantages
A user-friendly portable gas analyser for measuring hydrocarbons (methane and others) should have the following advantages:
- Reliable design (assembled in a housing protected from external influences) and, as a consequence, low inertia.
- Stable measurement accuracy with minimum possible errors.
- Compliance with GOSTs, availability of certificate and data on entering the device into the State Register of the Republic of Kazakhstan.
- Possibility to connect the portable methane gas analyser to a PC - via USB, RS-232, Bluetooth or other interface.
- Clear light and audible sound indication.
- Filtration (fine cleaning) of the samples taken.
- Possibility of graphical display of captured data.
