CORONA DP 405
MULTI-JET METER | DRY RUNNER
Application
Contact water meter for proportional control of pumps, motors, etc.
Metering with digital preselection of quantity and remote transmission of flow rates.
Features
- 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
- Encapsulated waterproof counter. Reading not obstructed by condensation of the transparent cover
- 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)
