APPLICATION： MEASURING THE TOTAL VOLUME OF COLD POTABLE WATER PASSING THROUGH THE METER（ALSO SUITABLE FOR PURE WATER）.
OPERATING CONDITION:
*THE MAX.ADMISSIBLE WATER PRESSURE 1.6MPa
*RESISTING WATER TERPERATURE OF 50℃
SPECIALITY:
* LOW START-UP FLOW-RATE
* INSTALLATION IN ANY POSITION (SUCH AS LEVEL, VERTICAL)
* POSITIVE ROTATING PISTON TYPE, WITH RELIABLE PERFORMANCE
* HIGH ACCURACY
* BRASS BODY
* ON REQUEST，THIS SERIES CAN BE EQUIPPED WITH THE PULSE DEVICE
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 C.
