Description
4.1
FSS100 overview
SITRANS FS Ultrasonic flowmeters measure different volume flow. Measurement is independent
of changes in liquid temperature, density, pressure and conductivity. The flowmeter is designed
for use on single phase liquids for measurement of:
• Volume flow
• Flow velocity
• Sound velocity
• Mass flow
• Total volume or mass
SITRANS FSS100 systems are maintenance free, self cleaning and have a service life of more
than 10 years.
As with the SITRANS FS230 and FS220 clamp-on systems, the SITRANS FSS100 sensors can
also be operated with the SITRANS FST020 and FST030 transmitters.
