Swirl flowmeter

Swirl flowmeter FS4000 present an economical solution for measuring low viscous liquids, gas and steam in volume and mass units employing integrated temperature measurement.
Available as PROFIBUS PA or FOUNDATION Fieldbus version.


Fieldbus & HART


Swirl flowmeter FS4000 is based on the principle of frequency measurement.
The measuring device in a 2-wire design has a freely configurable LCD display for actual flow rate and totalisation. Settings can be changed directly via push buttons or via magnet sensors with closed housing.
Additional to the fieldbus protocol a freely configurable switching output is always available. This can be used universally as pulse output, high / low alarm or for system supervision.
