GENERALFST4000 is a torque tube displacement type level indicating trans-mitter with intelligent data processing function. Through 18 years offield proven experiences accumulated by the existing model FST-3000, FST4000 has intensified its reliability by adding such featuresas SIL2 compatible functional safety, ATEX flameproof and field buscommunication of FOUNDATION Fieldbus .Varieties of materials and wide range of pressure ratings are avail-able to meet various applications such as high pressure and tem-perature boilers as well as low temperature down to minus 196℃ ofliquefied gases.
