E Vane Wheel Water Meter (LXSG-15E/F2~50E/F2)

DEFINITION:
Set of moving device that fitted into a closed conduit driven directly by water flow. Its turbine rotor rotates about the axis which is perpendicular to water flow.

WORKING PRINCIPLES:
Water flow drives vane rotate. Rotating times which is proportional to water flow speed are gathered, hence total volume passed through water meter is recorded.

CHARACTERS:
The counter type: Horizontal.
Sealed by special liquid keeping surface clear for long.
Low start flow.
Fit for low quality water.
Outside adjustable copper body. Painted available as demanded.
WORKING CONDITION:
Water temperature=45º C(Hot water meter=90º C)
Water pressure=1Mpa
MAXIMUM PERMISSIBLE ERROR:
From the minimum flow-rate (qmin) inclusive to the lower zone of the transitionalflow-rate (qt) exclusive: ± 5%.
From the transitional flow-rate (qt) inclusive to the higher zone of the maximum flow-rate (qmax) exclusive: ± 2%(hot water meter± 3%. )
