Electronic Water Meter
(Vertical Axial Flow Wheel Type EKDW / EFDW model)
Feature
- Electronic intelligent water meter is composed of 8 bit telegraphic communication output, LSI, LCD and Lithium battery.
LCD indicates the cumulative consumption and the data enables to the telecommunication metering system and automatic reading system. - Selectable body material between Lead Free Copper Alloy (CAC804) and Ferrous Casting Ductile (FCD450).
- Body constructed of FCD (Ferrous Casting Ductile) with powder coating for anti-corrosion.
