Swirl flowmeter
SwirlMaster FSS430

SwirlMaster FSS430 is a unique flow meter for volume flow applications when installation space is narrow.  It uses a two-wire transmitter with leading edge DSP-technology with excellent vibration compensation.  Intuitive operation directly through the glass makes the FSS430 incredibly user-friendly.  Flexibility in installation, due to low required inlet and outlet sections, can save up to 75% straight pipe run and enables installations in almost impossible situations.  FSS430 is ideal for installation into existing environment.
