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)

Meter for horizontal pipes
Meter for rising pipes
