*1 Use PFA tubes in an environment with a temperature of 40°C 104°F or less.
*2 Resin tubes that transmit ultrasonic waves.
*3 Gases that transmit ultrasonic waves. Measurement may be unstable due to the pressure inside of the pipe 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 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.
