^1 PFA tubing should be used in environments of 40°C or less. ^2 The plastic tube through which ultrasonic waves penetrate. ^3 The gas through which ultrasonic waves penetrate. Readings may become unstable depending on the pipe’s internal pressure and the type of gas. ^4 Accuracy improves with longer response times. As a rule, this is by a proportion of √(250 ms/response time)x. ^*5 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.
