Hot Water Flow Meters

"NUBIS" HOT WATER METER

PROPELLER WATER METER FOR HOT WATER 130°C WITH PULSE TRANSMITTERS

Features 

  • Permanent and efficient contruction, ensuring the flow of water in low loss of pressure and easiness in assembly in random waterworks installations.
  • Lowered weight of water meter.
  • Interchangeable and unified metering layer fitting to several sizes of body and assuring optimal water meter management.
  • Standard water meter in suitable for remote reading in AMR system.
  • The possibility of mounting the water meter in the intermediate position without the influence on the metrological parameters, larger possibilities in designing and modernising new used water meters connections.
  • Very good anti-corrosive and mechanical qualites of paint coat (powder paint-epoxy).
