China Petroleum Fushun Petrochemical Company
Project Name: Automatic Calibration Control System for Mass Flow Meter
The main technical parameters: Mass method device expansion uncertainty: 0.05% (electronic scale uncertainty 0.02%)
Test pipeline range: DN25 ~ DN150

Flow range: 1-200m3 / h

Project description: This project is a technical transformation of the original liquid (water) flow standard device by Fushun Petrochemical Company. Original control
The technology of the integrated system is backward, and the requirements stipulated in the verification cannot be completed. According to the actual situation on site, our company adopts advanced microcomputer automatic verification system
, So that the original quality law verification equipment has been completely transformed. At the same time, the original process pipeline was improved. The device
The minimum weighing electronic scale is 0.5T, and the maximum weighing electronic scale is 3T. Fully meet the calibration of mass flow meters below DN150.
Project Name: Automatic Verification System of Standard Equipment for Standard Gauges and Volume Tubes
The main technical parameters: Standard table method device expansion uncertainty: 0.5% (standard table uncertainty 0.2%)
Volume tube device expansion uncertainty: 0.05%
Test pipeline range: DN20 ~ DN250
Flow range: 1-300m3 / h
Project description: This project is based on the liquid (diesel) flow standard device of Fushun Petrochemical Plant No. 2 based on the original standard meter method and volume tube method.
After the technical transformation of our company, a microcomputer automatic verification system was added to automate and program the verification process. Especially the volume tube system,
The original three-ball valveless volume tube was completely controlled manually, the data reading error was large, and the labor intensity of the operator was very large. Add microcomputer
After the automatic verification system, the operation is simple, stable and reliable.
