[Selectable output]
It can be switched among flow rate, temperature switch output, analog output and IO-Link communication (option).
It also supports switching between PNP and NPN.

[Fluid temperature measuring function]
All models feature a fluid temperature measurement function as standard.
It can handle cold water to hot water of up to 95°C without the provision of a temperature sensor, improving the management level.

[Wide flow rate range]
The detection range of the flow rate lower limit is expanded to support a wide flow range.

[Flow rate adjustment mechanism]
The flow rate can be adjusted using the manual cock (option).

IO-Link communication (option) enables remote control from the host as well as data collection.
