Compensation of the temperature error of a system controlling process of tube inside surface coating

The article propose the modernization of the earlier developed system controlling coating process which based on the injection of material circulation ere the direct coating, simultaneous using of level sensors which have different principle of operation and the application in the regulation process of the temperature sensor which allows to realize the automatic compensation of changing of the current temperature of the material. All the offered improvements of system allow to provide equability of the coating on the length of a tube independently of material and environmental activity parameters.
