Application:

Corona E is an electronic multi-jet compact water meter designed for measuring cold and hot water (up to 90°C). Corona E has an efficient metrology (up to R=125) and can be used on all qualities of water. Corona E is available with different communication features : MBus or pulse.


Features:

  • Electronic sensor control for accurate flow metering
  • Lithium battery, lifetime up to 12 years
  • Optical ZVEI interface equiped as standard
  • Adjustable reading date for billing
  • Single-line 7-digit display for easy meter reading
