APPLICATION: MEASURING THE TOTAL VOLUME OF COLD POTABLE WATER PASSING THROUGH THE METER£¬IT'S SUITABLE FOR DOMESTIC USE.
OPERATING CONDITION:
WATER TEMP.: UP TO 50¡æ
THE MAX.ADMISSIBLE WATER PRESSURE: 1.6MPa (16bar)
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¨CRATES.
* SEALED & VACCUMIZED REGISTER WITHOUT ANY CONDENSATION PROBLEM.
* BE EQUIPPED WITH THE PULSE DEVICE (THE MEASURED WATER VOLUME OF PER PULSE MAY BE 0.01m3/Pulse AND 0.1m3/Pulse).
Maximum permissible error:
Between qt (included) and qs is ¡À2%;
Between qmin and qt (excluded) is ¡À5%.
NOTE: The technical data conform to ISO4064 standard, class B.
