Product Description

DEFINITION:
Key structure is made up of rotary carried helical blades which goes around as the same direction of water flow.

CHARACTERS: Removable structure, easy installation and maintenance.
Dry type, magnetic drive. Measuring system fit for uniform use.
An obvious advantage is that the pressure loss is less than 0.01MPa which is only 10% of rotating vane type. Cast iron body. Best choice for water supplying companies.

WORKING CONDITION:
Water temperature≤45ºC(Hot water meter≤90ºC)
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%.) .

APPLICATION

Measuring the volume of cold (hot) water passing through the pipeline

FEATURES

1. magnesium aluminum alloy die-casting cover

2. Dry-dial,magnetic drive

3. Vacuum sealed counter,keeps clear reading for long time

4. Removable measuring insert,easy installation and maitenance

5. High overload security

6. Wide measuring range

7. Measuring high flowrate with low head loss

8. Outstanding long-term accuracy even under extremeloads

9. Remote transmission device can be added upon request,Many kinds of sensors,such as Reed Switch ,Hall and Weagand canbe supplied upon request Pulse output may be 10 l/pulse ,100 l/pulse,1000 l/pluse

WORKING CONDITION
