ElMetro brand metrology stands for verification and calibration of gas analyzers
A necessity to control atmosphere conditions around industrial objects by means of gas analyzers arises in any petrochemical production.
Verification of gas analyzers is one of the most difficult tasks since it is followed by selection, purchase and storage of reference mixtures and arrangement of a safe working place for all controlled gases with different concentrations. Such task is especially essential for regional Automation and Metrology Centers where hundred types of gas analyzers from different production sites and services are sent to. In such situation stock of verification mixtures often exceeds 50-100 bottles and simultaneous verification of several similar gas analyzers is not available.
Verification stands for gas analyzers have quite short payback period in comparison to a separate set of reference gas mixtures whose cost is expensive and expiration time is not more than a year.
Structure:
Metrology stand for verification and calibration of gas analyzers consists of:
- switching stations for zero gas and verification gas mixtures (VGM) with built-in instruments for mixtures preparation and flow measurement;
- storage racks for bottles with VGM;
- storage racks for bottles with zero gases (installation outside premises is available);
- systems for heating gases to ambient temperature;
- exhaust chamber for gas analyzers;
- chambers caps for verification of gas analyzers specified in technical specifications of the stand;
- a work desk, a chair and a file cabinet;
- meteorological meter for measuring indoor humidity, temperature and pressure;
- additional racks, cabinets for storing instruments and documents and a trolley.
Instruments included in stands at option:
- 2, 3, 4-channel generators of gas mixtures GGS-R, GGS-T and GGS-K models - working standards of the 1st class;
- source of micro streams for mixed VGM;
- generator of zero gas GZG-01 – working standard of the 1st class;
- required instruments for measuring output current, voltage or frequency.
Functionality:
- preparation of gas mixtures in required concentration right at the stand (on a spot) – there is no longer a need for expensive VGM;
- obtaining zero-grade air directly in the laboratory – there is no longer a need for bottles with zero-grade air;
- compact size of a rack-mount type (occupied space from 2m2;
- advanced solutions of locating 40 pcs. liter bottles with zero gases outside premises to comply with safety regulations, providing heating of cold gas coming from the street;
- supply of ready gas mixtures from a selected bottle without overcommutation;
- structure with minimum stagnation zones which ensure gas purity with the previous mixture with minimum gas consumption for blow-out;
- high-quality draft with a mounting area for several gas analyzers;
- simultaneous verification of several gas analyzers at the one stand (consequential and parallel turn-on scheme – time saving and VGM), multichannel data reading of gas analyzers;
- bottles with ready gas mixtures are stored in special sections for a more convenient commutation;
- safety of operator – there are no leaks of poisonous and explosion hazardous mixtures inside the laboratory;
- keeping records on verified gas analyzers, preparation and printing of reports according to standards of enterprises – editable report forms;
- full set of verification chambers produced according to the drawings of gas analyzer’s manufacturer;
- modern design, logical and convenient commutation of VGM;
- full installation and field training are available.
