1. General
This is a battery built-in type electromagnetic water meter that M. Faraday’s Electromagnetic Induction Law isapplied. This meter demonstrates its wide measuring range and high durability as there is no mechanicalmoving part in the flow measurement tube of the meter. This meter has the external output corresponding to theremote monitoring / the remote control.
