Product Type:
LXHY-15E-20E LXHG-15E-20E VOLUMETRIC ROTARY PISTON WATER METERRemark: 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 Mechanical parts use of high-quality material to ensure a stable characteristic (The LXHG is dry type.The LXHY is Liguid sealed register).
WORKING CONDITION:
Water temperature: <=50
•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)
