Ultrasonic flow meters are mainly used for measuring the flow of liquid media in fire protection pipelines and other applications. The principle of ultrasonic flow meters is to use ultrasonic transducers to send and receive ultrasonic waves, measuring the time difference of propagation in the downstream and upstream media to determine the flow velocity. In the downstream direction, the ultrasonic wave speed increases, while in the upstream direction, the speed decreases. Therefore, the same propagation distance will have different propagation times. Based on this time, the flow velocity is obtained, and then the flow rate is calculated from the flow velocity.

▌Structural Characteristics and Applications

Ultrasonic flow meters are mainly used for measuring the flow of liquid media in fire protection pipelines and other applications. The principle of ultrasonic flow meters is to use ultrasonic transducers to send and receive ultrasonic waves, measuring the time difference of propagation in the downstream and upstream media to determine the flow velocity. The flow velocity of ultrasonic waves increases in the downstream direction and decreases in the upstream direction, resulting in different propagation times for the same distance. Based on this time, the flow velocity is obtained, and then the flow rate is calculated from the flow velocity.

Ultrasonic flow meters are suitable for fire protection systems in residential units, buildings, commercial squares, etc. Functional characteristics of ultrasonic flow meters: the body of the ultrasonic flow meter is a straight-through integrated structure, made using precision casting technology. It has a hollow structure, allowing unobstructed water flow, particularly suitable for the heating water quality and working conditions required in China, with lower pressure loss. The structure is simple, making installation and maintenance convenient. It is completely unaffected by impurities, chemicals, and magnetic materials in the medium, ensuring stable and reliable operation. The measurement structure has no moving parts, ensuring no wear and tear, and the measurement accuracy is not affected by the usage cycle. It employs advanced low-power design and can be powered solely by batteries. It uses imported ultrasonic dedicated detection chips for higher accuracy. It can be installed both horizontally and vertically, making it extremely convenient and practical.
