Application
Type DEM122 single phase impulse watt-hour meter is a kind of
mechanism-electronic integrative new-style watt-hour meter which is
designed and manufactured by our company on the base of type DDM862
single phase impulse watt-hour meter and developed for supplying
collecting transcription meter system impulse group of formed direct
ratio with using electricity quantity. The meter is suitable for
measuring rated frequency 50Hz single phase AC active energy
electric energy. Its technical performance are completely conform to
National Standard GB/T15283-94 and international standard
IEC60521.Functions and features The meter use type DEM072 single
phase watt-hour meter as basal meter and add a impulse occurring
device sampling by magnetoelectricity sensor. It has the following
functions: adjust impulse width, impulse output indication,
anti-dithering, wide temperature working range (-40~80℃)high
reliability and long life, can choose inner placed current as power
supply electrical source.
