APPLICATION: MEASURING THE TOTAL VOLUME OF COLD POTABLE WATER PASSING THROUGH THE METER，IT'S SUITABLE FOR DOMESTIC USE.
OPERATING CONDITION:
THE MAX.ADMISSIBLE WATER PRESSURE: 1.6MPa.
WATER TEMP.: UP TO 50℃
SPECIALITY:
*Magnetic shield structure, with which the water meter can
not be influenced by outside magnetic fields.
* If be replaced with the appropriate materials, it can be used for the
hot water meter (the water temperature is above 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.
