What should you check before installing an ultrasonic flow meter on a high-temperature flue? Part 2 focuses on installation precautions, laser alignment, positive pressure, high-temperature hazards, and flange sleeve alignment. This video explains the key safety and alignment considerations before installing ultrasonic transducers on an operating flue or stack. It covers positive and negative flue gas pressure, high-temperature conditions, laser alignment, flange sleeve positioning, purge-air connections, and internal obstructions. The video also demonstrates how to use a laser alignment fixture and visual target plate to verify that the two openings are correctly aligned. Special attention is given to working with hot stack walls and positive-pressure flue gas. Proper alignment helps establish the correct ultrasonic acoustic path between the upstream and downstream transducers. This practical guide is intended for engineers, installation technicians, and commissioning personnel working with industrial ultrasonic gas flow measurement systems.
