description: Topic of the final qualification work: "Instrument for measuring the velocity of gas flow in aggressive conditions".Â Â Â Â Â Â Â Â Â  This work is devoted to the development of metrological equipment for measuring the velocity of the gas flow coming out as a result of emission from the floating areas of an active volcano. Tasks that were solved during the work: 1. Analysis of the main methods for measuring the velocities of gas flows and the choice of the physical principle of measurement. 2. Selection of elements, development of an analog measuring channel circuit, as well as the software part of the device. 3. Development of recommendations on methods for protecting the device from exposure to high temperatures and gas compositions with a high sulfur content and metal vapors. The developed device is based on the Arduino Uno controller. The analysis of errors is carried out. The development of the measuring channel was carried out in the NI Multisim and Proteus design environments, the software part was developed in the Arduino IDE environment, the calculation of errors was carried out using the MATLAB software package.
