APPLICATION：MEASURING THE TOTAL VOLUME OF COLD POTABLE WATER PASSING THROUGH THE METER
SPECIALITY：
◆ BURGLARPROOF FUNCTION
◆ SPECIAL BURGLARPROOF STRUCTURE OF THE CAP AND THE PROTECTIVE RING
◆ HIGH ACCURACY
◆ 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°,WHICH IS 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.
