Application:

Domestic water meter with measuring capsule


Features:
  • Only the complete measuring capsule needs to be replaced regularly at the end of the calibration period - the meter housing remains fitted in the pipeline
  • Only the impeller operates in the wet chamber to prevent faults due to sediment
  • A DIN DVGW-approved non-return valve can be installed in the meter housing as option
  • Encapsulated counter can be rotated to any position for easy reading
  • Integrated measurement outputs as standard
  • Sensors for remote reading (digital) and flow rate measurement (analogue) can be retrofitted on site
  • Multi-jet impeller meter in completely dry-running design with magnetic coupling
  • For horizontal installation
