*1 For fluids through which ultrasonic waves propagate, and which do not contain a large quantity of bubbles. Detection may be unstable depending on the type and condition of the pipe.
*2 When the display unit is mounted directly on the sensor head, there is a de-rating according to the ambient temperature and fluid temperature.
*3 When using with fluids at temperatures of 140°C 284°F or greater, equip with the separately sold ultra-high-temperature couplant FD-HK1/HK2/HK3. Furthermore, the display unit must be separated from the sensor based on the de-rating.
*4 This is the guaranteed value from verification performed at KEYENCE inspection facilities. Measurement error may occur depending on the type and condition of the customer’s pipes, the type of fluid, the fluid temperature and other factors.
*5 This is the value for when the zero point is adjusted, for a constant 25°C 77°F environment, taking into account the linearity and span error.
*6 In a state where flow velocity distribution is stable. Does not include pulsation and fluctuations in flow velocity distribution due to equipment factors. Please also convert the given F.S. (full scale) using the rated flow range.
*7 Supports IO-Link specification v.1.1/COM2 (38.4 kbps). Setting files can be downloaded from the KEYENCE website (www.keyence.com). IO-Link is a trademark or registered trademark of PROFIBUS Nutzerorganisation e.V. (PNO).
*8 Can be used when two temperature sensors (sold separately) are connected.
*9 640 mA or less including load. When connecting devices such as temperature sensors, please add on the current consumption of each sensor (up to a maximum of 830 mA or less).
*10 When a USB connection is in use, IP65/67 compliance is impaired.
