The key factor in measuring the tank gauging system

Tank gauging system and work with standard system test, generally a standard method of comparing standard thermometer was seized by the thermometer, that comparison done. Due to the large fuel management software range specified system scale, interpolation different system zones of different instruments, but the actual tank gauging system for its application system range is different, so the different system zones and measuring instruments type its tank gauging system methods are different. Various industries and regions thermometer traceable to standard equipment in various industries and regions, the thermometer calibration used in the construction industry can be traced back to the local metering station and then traced to the Chinese China Institute of Metrology fuel management software reference, can also be traced to China Building Science School building energy and environment Test Center, and then finally traced to the China Science and Chinese Academy of reference system measurement. Temperature and the length, mass, time, tank gauging system current, luminous intensity, amount of substance (mole) and known seven basic physical quantities. Thermodynamic temperature (symbol T) is the basic physical hand, its unit is Kelvin (Kelvin symbol K), defined as the thermodynamic tank level gauge system of the triple point of water, 1 / 273.16. As the previous definition of the temperature scale used and 273.15K (freezing) to tank gauging system represent the difference between the temperature, so that each method remains. By definition, equal to the size of degrees Kelvin, the temperature difference can also use Celsius or Kelvin to represent.
