APPLICATION：MEASURING THE TOTAL VOLUME OF HOT WATER PASSING THROUGH THE METER，IT’S SUITABLE FOR DOMESITIC USE.
SPECIALITY：
* SIMPLY DESIGN
* HERMETICALLY SEALED REGISTER
* HIGH ACCURACY
* NEGLIGIBLE HEAD LOSS AT WORKING FLOW-RATE
* MAGNET DRIVE WITH ANTI-MAGNETIC
* HIGH-QUALITY MATERIAL WITH LONG LIFE OF SERVICE
WORKING CONDITION:
* The max. admissible water pressure: 1.6MPa
* Water temperature: up to 90℃
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.
