Automated Information Systems of Routine Metering for Fluid, Gaseous and Bulk Materials and Power Resources
|
Purpose
Automated information systems of routine metering for various flows and power resources are aimed for metering of incoming materials and shipped final products in order to estimate balance and production efficiency at metallurgical, petrochemical, oil refinery and other branches of industry.
Types of media to be metered: Liquid, gaseous, bulk materials and well as packed and palletized products and power resources.
The list of media and regulatory documents on which the metering is based, is presented in the table below.

Functions
The main functions of automated information systems of routine metering are as follows:
- Real time metering and calculation of various media and power resources:
- Monitoring of incoming, consumed, shipped and stored media and power resources
- Estimation of balances as per type of raw material/product
- Document turnover automation
- Transfer of data to other company management levels
- Storing data in server databases
- Reliable data exchange with servers of other systems
|
|
Components
Automated information system of material and power resources metering consists of the following:
- Process part consisting of pipelines, tanks, conveyors, bins, batchers etc as well as instruments
- Hardware and software, including data processing system, power supply system, operator's automated workstation, database servers etc.

Features
The advantage of our Company is development of automated data systems of routine metering and combining equipment by Russian and Western manufacturers (Emerson, Yokogawa, Siemens etc.) with our own equipment.
|
|
For metering liquid and bulk materials by means of batchers control equipment is applied.
The most significant advantage of metering systems based on the equipment manufactured by SME TEC is the opportunity to unify several systems into one system with one central automated operator's desk and central server.
Integrated solutions from SME Tomsk Electronic Company allow integration into supplementary control systems - gas detection, local control devices and overloading protection etc.
