Workshop on Verification of Electromagnetic Flow Meters

The Arab Industrial Development, Standardization and Mining Organization (AIDSMO) held, on Wednesday, 17 September 2025, a virtual workshop on the verification of electromagnetic flow meters, with the participation of 56 attendees from Arab countries. The workshop was led by Eng. Muhannad Azmouti, Chair of the Metrological Verification Committee for Non-Water Liquid Flow Measurement Instruments at the Palestinian Standards and Metrology Institution.

The workshop included a presentation on “Verification of Electromagnetic Flow Meters”, which introduced the concept of metrological verification for electromagnetic flow measurement instruments, emphasizing its importance in ensuring measurement accuracy, improving product quality, and reducing waste and costs. The presentation also covered the components and operating principles of the meters, based on Faraday’s law of electromagnetic induction, and highlighted their advantages over other technologies, including high accuracy, insensitivity to density or viscosity, and absence of moving parts.

The workshop further included a comparison of different flow measurement technologies, such as mass flow meters, volumetric flow meters, differential pressure meters, and magnetic meters, while emphasizing the classification of measurement systems and factors affecting reading accuracy, such as temperature, pressure, flow rate, and installation. The importance of regular calibration and maintenance was also discussed.

Practical verification steps were demonstrated, starting from preparation and installation, selection of verification points, measuring flow rates, adjusting zero deviation, checking linearity and repeatability, to documenting results and issuing final reports. The workshop concluded by highlighting the significance of these procedures in ensuring measurement fairness across industrial sectors, thereby enhancing production efficiency and promoting transparency.
