APPLICATION： MEASURING THE TOTAL VOLUME OF COLD POTABLE WATER PASSING THROUGH THE METER（ALSO SUITABLE FOR PURE WATER）.
OPERATING CONDITION:
*THE MAX.ADMISSIBLE PRESSURE 1.6MPa
*RESISTING WATER TEMPERATURE OF 50℃
SPECIALITY：
* NEGLIGIBLE HEAD LOSS AT WORKING FLOW-RATE
* INSTALLATION IN ANY POSITION (SUCH AS LEVEL, VPRIGHESS)
*SEMI-POSITIVE OSCILLTING PISTON TYPE, DIRECT TRANS MISSION WITH RELIABLE PERFORMANCE
* HIGH ACCURACY
* PLASTIC BODY（ON REQUSET，ALSO PROVIDE BRASS BODY）
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.
