ALGORITHM FOR SELECTING A FLOW METER WITH OPTIMAL PARAMETERS

Problems. In many cases, the problem arises of choosing from a variety alternatives to measuring instruments necessary for parameters technological process. So as that with different designs, operating principles and technical are produced by manufacturers. One important problems in development these systems is selection optimal operational metrological characteristics accordance manufacturer's specifications terms reference system design.
 Methodology. Multiple criteria decision-making (MCDM) used order solve related several criteria. The high accuracy sensors ensure accurate readings, although there involved process: flow rate; gas or gases used; temperature; pressure; pressure drop; price; accuracy; response time; warm-up stable measurement range (turndown) selected.
 Findings. Selection process meter information-measuring considered. Criteria meters studied, shown multi-criterial problem. Algorithm proposed. Proposed algorithm based on AHP method TOPSIS. An idea following. İnitially experts select some alternatives, which meet all requirements suppliers. At next step relative importance calculated. After decision matrixes composed determine preferences goals. 
 Originality. Better alternative determined ranking alternatives. Practical value. Applying proposed increases reliability final automates using corresponding software.
