Product  Type: LXSG-15E-50E  ROLLING WING DRY WATER METER
Remark: APPLICATION:
This range of water meter is used to measure the total quantity of cold potable water which consumed in houshold or a resident unit, passing through the pipeline.
FEATURES:
This is a dry-type water meter.Its counting and measuring devices are driven by magnetic coupling. It is characterized by easy reading,good antifreezing property and ability to permanently keep the reading clear.
WORKING CONDITION:
Water temperature:<=40•C Water pressure:<=1MPa
COMPLIANCE WITH STANDARD: ISO 4064 (GB/T778-1996)
INDICATING ERROR:
At low zone is+-5% from minimum flow rate(qmin)to transitional flow rate(qt)exclusive boundary
At high zone is+-2% from transitional flow rate(qt) to overload flow rate(qs)
