APPLICATION£ºMEASURING THE TOTAL VOLUME OF COLD POTABLE WATER PASSING THROUGH THE METER
SPECIALITY£º
* GEARING BOX IS MADE OF HIGH QUALITY COPPER
* 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¡ã,WHICH IS CONVENIENT FOR INSTALLATION.
WORKING CONDITION:
* THE MAX. ADMISSIBLE WATER PRESSURE: 1.6MPa
