Fluid level control with Elko EP-0

ELKO EP is one of the world's leading manufacturers of electronic equipment for residential, office and industrial automation. We have been supplying the world over for the past 25 years; our main domain is primarily relays, but we also supply wireless products and IoT products. But we're not just focused on products; we also propose comprehensive and highly effective solutions.


  • Relay is designed for monitoring levels in wells, basins, reservoirs, tanks,...
  • In one device you can choose the following confi gurations:
    - One-level switch of conductive liquids (by connecting H and D).
    - Two-level switch of conductive liquids.
  • One-state device monitors one level, two-state device monitors two levels (switches on one level and switches off on another level).
  • Adjustable time delay on the output (0.5 - 10s).
  • Sensitivity adjustable by a potentiometer (5 - 100 kΩ).
  • Measuring frequency 10 Hz prevents polarization of liquid and raising oxidation of measuring probes.
  • Galvanically separated supply voltage UNI 24 to 240 V AC/DC.
