APPLICATION：MEASURING THE TOTAL VOLUME OF COLD POTABLE WATER PASSING THROUGH THE METER
SPECIALITY：
* HARDENED GLASS AND BURGLARPROOF FUNCTION
* SPECIAL BURGLARPROOF STRUCTURE OF THE CAP AND THE PROTECTIVE RING
* 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 DATAS CONFORM TO ISO4064 STANDARD, CLASS B.
