Product  Type: LXH-20A  VOLUMETRIC ROTARY PISTON 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:
Adopt volumetric rotary piston principle of measurement with conformity to ISO 4064 class C¡¢D High sensitivity enables the accurate measurement even at a low flow rate of 4 L/h No location limitation for instailation.Accuracy is not to be affected wherever intailed at a horizontal,vertical or inclined pipeline.Reginter is sealed with a special liquid to keep a clear reading is long term service mechanical parts use of high-quality material to ensure a stable characteristic.

WORKING CONDITION:
Water temperature:<=50•C Water pressure:<=1MPa
COMPLIANCE WITH STANDARD: ISO 4064 (GB/T778-1996)

COMPLIANCE WITH STANDARD:ISO 4064 Class C¡¢D (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)
