Main Characteristics :
Fully dry dial meter with no gear reduction in the wet chamber
Wear resistant tungsten carbide/sapphire bearing
Magnetic coupling protected against magnetite
Pulse sender safe from interface
Easy to repair construction with external regulation
DESCRIPTION
The flow sensors AN 130 are multi-jet dry dial vane impeller hot water meters, suitable for installing in central heating and cooling systems and remote warning systems. With their built-in pulse sender they are approved as low sensors for heating meters according the European measuring instruments directive (MID) 2004/22/EG
Versions for horizontal, rising and falling flow directions with screwings (PN 16) or flanges (horizontal flow, PN 25) are available.
