^1 To ensure stable detection, it is recommended to use a pipe inner diameter that is at least equivalent to the inner diameter of this product. ^2 Gases that transmit ultrasonic waves. Measurement may be unstable due to the pressure inside of the pipe and the type of gas. ^3 This value is guaranteed by KEYENCE inspection facilities. Errors will be introduced by factors such as the condition and type of pipes as well as the temperature and type of gas. ^4 This specification is valid when sufficient straight sections of pipe are provided and the flow velocity distribution is stable. This value does not take into account the effects of fluctuations in flow velocity distribution due to facility factors. ^*5 Accuracy improves with longer response times. As a rule, this is by a proportion of √(250 ms/response time)x.
