^1 The gas must be uniform and capable of transmitting ultrasonic waves. Measurement may be unstable due to the pressure inside of the pipe and the type of gas. ^2 This value is guaranteed by KEYENCE inspection facilities. Errors will be introduced by factors such as the type and status of the pipe and the type and temperature of the gas. ^3 This is the value when considering linearity + span error in a stable environment with a temperature of 25°C 77°F. ^4 Defined with stable velocity of flow distribution. Does not include pulsations and fluctuations in the velocity of flow distribution primarily attributable to the equipment. ^5 The linearity error characteristic due to the pipe is not included in this value. ^6 It is possible to reduce zero point errors by performing an origin adjustment. ^7 This is the value within the range where measurement accuracy is guaranteed. ^8 When Bi-directional is specified, the following functions cannot be used. The selection of the comparison view/leak ratio view/static leakage, the measurement/display of the leakage amount/integrated flow, the setting of the target value/warning set value, and money conversions. Also, the I/O settings are limited as shown below. • ch.1: Pulse(+) mode • ch.2: Pulse(-) mode, Error output mode, Integrated flow reset, Flow zero input, Origin adjustment input ^9 IO-Link: Compatible with specification v1.1/COM1 (4.8 kbps).
