What must be prepared before installing ultrasonic transducers on a high-temperature flue? Part 3 covers purge-air preparation, cooling systems, flange sleeves, signal cables, and installation checks. This video explains the preparation work required before installing the ultrasonic probes. It covers the purge-air control system, purge-air distribution box, cooling fan, flange sleeves, signal cables, temperature sensors, and purge-air flow meters. Before probe installation, the purge-air system must be operating correctly. The video shows how to check the front-end purge air and prepare the end-face and air-sleeve purge systems for high-temperature operation. It also explains the typical purge-air flow range of 30–50 L/min, which should be adjusted according to actual flue gas pressure and site conditions. The guide is designed for engineers and technicians preparing high-temperature flue gas ultrasonic flow velocity meters for field installation and commissioning.
