APPLICATION：MEASURING THE TOTAL VOLUME OF COLD POTABLE WATER PASSING THROUGH THE METER，IT IS SUITABLE FOR DOMESITIC USE.
SPECIAL FEATURE：
* SIMPLE DESIGN
* HERMETICALLY SEALED REGISTER
* MINERAL TEMPERED GLASS
* HIGH ACCURACY
* NEGLIGIBLE HEAD LOSS AT WORKING FLOW-RATE
* MAGNET DRIVE WITH ANTI-MAGNETIC SHIELD
* HIGH-QUALITY MATERIAL WITH LONG LIFE OF SERVICE
* REMOTE READING SYSTEM, RELIABLE IN DATA COLLECTING
* WITH THE PULSE DEVICE, AND THE MEASURED WATER VOLUME OF PER PULSE MAY BE 1L/P, 1L/P OR 1L/P.
WORKING CONDITION:
* The max. admissible water pressure: 1.6MPa
* Water temperature:
Cold water temperature up to 50℃
Hot water temperature up to 90℃(Available)
Maximum permissible error:
Between qt (included) and qs is ±2%;
Between qmin and qt (excluded) is ±5%.
NOTE: The technical data conform to ISO4064 standard, class B.
