APPLICATION: MEASURING THE TOTAL VOLUME OF COLD POTABLE WATER PASSING THROUGH THE METER.
SPECIALITY:
☆ THE HARDENED GLASS
☆ HIGH ACCURACY AND LARGE MEASURING RANGE
☆ NEGLIGIBLE HEAD LOSS AT WORKING FLOW-RATE
☆ MAGNET DRIVE WITH ANTI-MAGNETIC
☆ HIGH-QUALITY MATERIAL WITH LONG LIFE OF SERVICE
☆ RELIABLE IN DATA COLLECTING , HERMETICALLY SEALED REGISTER
☆ THE REGISTER IS SEALED AND IT COULD BE IN ANY POSITION
WITHIN 360°,CONVENIENT FOR INSTALLATION.
WORKING CONDITION:
☆ THE MAX. ADMISSIBLE WATER PRESSURE: 1.6MPa
☆ WATER TEMPERATURE: WATER TEMP UP TO 50℃
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.
