1、The first summarizeToday,internal sample of liquid dielectric in the oiltank is performed by ISO3170(GB/T4756-1998)Petrol liquid product handicraft sample law.It is impossibly to control accurately sample process. Usually the sample will not be exact.Performing personnels will feel tired as usual be
2、cause of hardwork.When rain or snow, climb oiltank that is a very dangerous job.When getting a sample at top of oiltank,easily volatile and noxious dielectric will injure someones，at one time，it will not be in favour of environment and the medium of oiltank will be polluted by other things from envi
3、ronment.For solving these problem, we have developed ” The auto control getting sample from oiltank” that according to ISO3170(GB/T4756-1998 criterion,it has achieved that liquid sample at different level of oiltank will be sampled. The machine operation is very simply、very accurate、excellently repe
4、ated,its structure is simple and it will be install very easily. It will not pollute the environment too. The sample machine has been awarded nationalpatent and the second prize of the sino petrol & chemical industry automation vocation 2010 year. The auto control getting sample from oiltank , its s
5、tructure is sample, it will be install very easily、its operation is very simply、very accurate and it will not pollute the environment. At present, its technology has been take the lead in the like product.We have gotten by the auto control getting sample from oiltank the patents and the credits that
