ntrotek’s IntroFlow™ non-invasive flow detection devices incorporate the latest ultrasonic technology for flow measurement. The non-invasive concept provides a platform for non-contact measurement where safety, hygiene and cleaning are of concern. This free-entry sensor is designed for easy tube installation and can be accommodated for various tube sizes. Fully integrated electronics yield the smallest footprint with simple interface to medical and industrial applications. The standard configuration outputs a voltage frequency that is proportional to liquid flow velocity. Absent tube and air detection are fault outputs for added value.
