MULTI-JET METER | DRY RUNNER

Contact water meter for proportional control of pumps, motors, etc. and for remote transmission of flow rates.

  • Multi-jet impeller meter in completely dry-running design with magnetic coupling
  • Only the impeller operates in the wet chamber to prevent faults due to sediment
  • Counter can be rotated to any position for easy reading
  • Built-in pulse contact (with cable 2 m) cast in a waterproof enclosure and easily replaceable
  • Max. contact load 24 V (SELV) 0.2 A
  • The outlet is prepared for installing a non-return valve (DVGW approved)
  • Special version hard nickel-plated available
