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:
- Multiple-jet, dry, magnetic drive.
- Vacuum sealed counter, frost proven, keeping clear reading for long,
- Antimagnetic construction.
- Meter body made of either brass.
- Outside or inside adjustable meter body.
- For hot or cold water, remote transmission device can be added upon request.
- All technical figures are conformed with GB/T778.1~3-1996 which is equivalent to ISO4064 Standard Class B.
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 transitional flow-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%.)
