Vortex Flowmeters

SWIRLMAX is a 2-wire, all-in-one type vortex flowmeter with temperature and pressure sensors. The VFM4200 can easily correct flow measurements of steam and gases for temperature and pressure. There is no need for additional sensors and correctors. The VFM4200 is ideal for managing the energy of steam and gases.
