Product Description
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:
Outside adjust copper body, painted available as demanded.
Counter:vacuum sealed, frost proven, keeping clear reading for long.
Magnetic transmission free from disturbance.

WORKING CONDITION:
Water temperature¡Ü45ºC(Hot water meter¡Ü90ºC)
Water pressure¡Ü1Mpa  
 
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%.)
