Sick's FFU is a non-contact ultrasonic flow sensor which detects the flow volumes of conductive and non-conductive liquids.
The FFU flow sensor has a compact design which enables it to be used in a wide range of applications including those with limited space.
The Sick FFU is rated IP67 and features a seal free sensor design with high quality polysulfone (Ultrason S), which not only makes it possible to use the device in harsh ambient conditions, but also ensures high process reliability.
The FFU flow sensor has a large text display to ensure comissioning is hassle free and quick.
