It is used to weigh oil in batches and transfer a certain amount of oil to mixer. Adding accuracy≤0.3%. 

In the adding system, each inlet is equipped with solenoid valve to control oil passage, and multichannel oil enters into upper tank through inlet. After weighing, the bottom electric ball valve is opened, the oil enters the lower tank, and is conveyed into mixer by the gear pump to carry out the material spraying.

Synchronized with the batching system, oil data has access to the report system and can connect with ERP.
