”Flow and Volume” Laboratory

The ”Flow and Volume” Laboratory undertakes, preserves and disseminates through modern equipment the measurement units of: volume and flow. The mentioned measurement units are crucial for heavy industry, food, chemical, light and textile industry, medicine etc.

Main objectives of the laboratory are:

  • Assurance of uniformity, accuracy and traceability of measurements on the territory of the Republic of Moldova.
  • Management, maintenance, storage, preservance of measurement standards and of the equipment owned by the laboratory.
  • Research of the National Measurement Standards Base and of the equipment owned by the laboratory.
  • Storage, reproduction and dissemination of measurement units from national and reference measurement standards to the other standards and measuring instruments according to ierarchic schemes.
  • Participation in interlaboratory comparisons at international level for demonstration of laboratory measurement capabilities. 
  • High accuracy measurements performance.
  • Maintenance and continuous improvement of the quality management in the laboratory.
  • Development of calibration procedures for satisfying the necessity of economic agents regarding the traceability of measurement units.
