Faqs:
  • What is the working principle of the FTL50 Vibronic Level Transmitter?
    The FTL50 uses a metal tuning fork that vibrates at its natural resonance. When liquid covers the fork, the vibration dampens, and the frequency shift is detected, triggering a switch state change. This principle works independently of conductivity, dielectric constant, density, and viscosity.
  • What are the key applications for the FTL50?
    The FTL50 is used for overfill protection in tanks, dry-run protection for pumps, leak detection in pipelines, and safety-critical loops. It's suitable for water & wastewater, chemical and petrochemical, oil & gas, food & beverage, and power plants.
  • What certifications does the FTL50 have?
    The FTL50 is certified for functional safety (SIL2/3), explosion protection (ATEX, IECEx, FM, CSA, NEPSI), marine approvals (ABS, BV, DNV GL, LR), and hygienic standards (EHEDG, 3A, FDA-compliant materials for FTL51C).
