Tank calibration software, the overall configuration of explosion-proof industrial, mechanical part and an electronic control part gas station software the control technology at home and abroad the most advanced, both to ensure the correction velocity, and satisfy the synchronization import oil and liquid level height variation in the tank calibration software process of correction. The main components of liquid level instrument: Qingdao expensive and itself is the level of professional manufacturers, the volume of the tank liquid level instrument equipped with automatic tank automation system is the best way selection, so that the liquid level instrument resolution accuracy. At the same time to ensure the minimum level fluctuation Tank calibration software process, a tubular sheath increase on the basis of the original product, and the data acquisition of multiple check, guarantee the real-time liquid level tank calibration software show consistency with the actual level of. Users in the tank capacity in the process of correction, such tank calibration software as liquid level instrument failure, expensive and technology will provide rapid, timely service, and guarantee gas station management system the product spare parts supply. The correction process safety, high-speed, accurate. At the same time, flow parameters can be modified by controlling the test instrument, the accuracy of the flowmeter can be adjusted to 8/10000, to help the user regular self calibration.
The temperature probe is generally a thermocouple or RTD, thermocouple temperature voltage changes, the thermal resistance temperature resistance change, that is good.

Establish standard temperature calibration apparatus species
Temperature measurement apparatus and working with the temperature calibration, the general standard is a standard method of comparing the thermometer was seized by the thermometer, which completed comparative law. Due to the large temperature range specified temperature scale, interpolation different temperature zones of different instruments, but the actual temperature measuring instruments for its application gas pump filters indicator range is different, so the different temperature measuring instruments and their measurement type is different. Various industries and regions tank level gauge system traceable to standard equipment in various industries and regions, the temperature calibration used in the construction industry can be traced back to the local metering station and then traced to China China Institute of Metrology on the basis of temperature, it can be traced to China Building Science School building energy and environment Test Center, and then finally traceable to China, Chinese Academy of Sciences baseline automatic fuel dispenser measurement. Temperature and length, mass, time, current, luminous intensity, amount of substance (mole) and known seven basic physical fuel transfer hand pump quantities. Thermodynamic temperature calibration (symbol T) is the physical fundamentals hand, it is expressed in Kelvin (Kelvin symbol K), defined as the thermodynamic temperature of the triple point of water is 1/273.16. As the previous definition of the temperature scale used and 273.15K (freezing) to represent the temperature difference, so it retains all methods. By definition, equal to the size of degrees Kelvin, the temperature difference can also use Celsius or Kelvin to represent.
