The SITRANS FSS100 is ideal for installation in a new system. Compared to an ultrasonic clamp-on flowmeter, the sensors are installed directly into the existing pipe system. After installing the sensors and transmitter, you have an uncalibrated inline flowmeter. It is a much cheaper solution than installing an inline flowmeter with a tube into the system.
The proportional flow factor K is determined by wet calibration or calculated by "AUTO" in case of manual programming of mechanical/geometrical pipe data (Retrofit only). The transducer angle (θ), distance between sensors (L) and pipe dimension (D and D ) are shown in the figure below. SITRANS FSS100 Installation Manual, 12/2023, A5E52595000-AA...
