Application:

CORONA C is a main meter designed for metering cold water. It is available in different lengths and standardised diameters. CORONA C has a R=160 MID approval for horizontal installation. Thanks to the direct transmission through the stuffing-box, the meter is particularly reliable and sensitive to low flowrates. CORONA C is fitted with a register with protected 5-digit roller counter which remains optimally readable in all environments.


Features:
  • Multijet meter
  • MID approval up to R=160
  • Good starting flowrate
  • Insensitive to tamper
  • DN 15 to 40
  • Protected 5-digit roller counter
