CORONA DP 405

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
