  • World's only wired HART vibrating fork level detector.
  • Dry/wet switching optimized for many media types. Includes wet sand settings for managing tank and separator efficiency.
  • Dry/wet switching reliability is maximized even when the media properties are unknown. Especially important in small tanks and pipes where levels may rapidly change.
  • Detects issues which may indicate coating or corrosion of the fork, and corrosion from water ingress.
  • Excellent diagnostics coverage enables true predictive maintenance.
  • Ready-for-upgrade kits to future-proof investments.
