^1 For stable detection, a pipe inner diameter equal to or greater than the inner diameter of this product is recommended. ^2 The gas through which ultrasonic waves penetrate. Readings may become unstable depending on the pipe’s internal pressure and the type of gas. ^3 This is the guaranteed value from verification performed at KEYENCE inspection facilities. Errors may occur according to the type and condition of the customer’s pipes, the type of fluid, the fluid temperature, and other factors. ^4 The definition assumes that the flow velocity distribution is stable with a sufficient straight pipe segment. Does not include pulsations or changes in flow speed distribution caused by equipment. ^*5 Accuracy improves with longer response times. As a rule, this is by a proportion of √(250 ms/response time)x.
