FFU flow sensor - non-contact flow measurement

The non-contact FFU ultrasonic flowmeter detects the flow volume of conductive and non-conductive liquids. Swimming against the current requires more strength than with the current – this is the simple fact on which ultrasonic flow measurement according to the phase difference process is based. Its compact design enables the device to be used in a wide range of applications, including those with limited space. This sensor with an enclosure rating of IP67 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 large cleartext display also helps provide simple, fast, and hassle-free commissioning.
