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:
* LARGE MEASURING RANGE, HIGH FLOW ACCURACY.
* STEADY ERROR CURVE.
* LONG LIFE OF SERVICE
* RELIABLE OPERATION.
* MAGNETIC SHIELD PROTECTION.
* NEGLIGIBLE HEAD LOSS AT WORKING FLOW – RATES.
* SEALED & VACCUMIZED REGISTER WITHOUT ANY CONDENSATION PROBLEM.
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.
