Turbine water meter
Turbine water meter also named woltman water meter,Turbine water meter also belongs to a kind of speed water meter.It is suitable for use in large-diameter pipeline (DN80-DN600), which is characterized by large flow capacity and small pressure loss.
Introduce
Turbine water meter also named woltman water meter.When the water flows into the water meter, it impacts the water meter along the axis direction, and the impeller rotates and flows out. The rotating speed of the impeller is directly proportional to the water flow speed.the total amount of water passing through the water meter is displayed on the indicating device.
Function
- Wide measuring range.
- High measurement accuracy
- Dry magnetic transmission structure
- Six digit enlarged digital wheel displays.
- The detachable metering structure is convenient for maintenance.
- Stainless steel filter screen effectively protects the measuring mechanism.
- Stainless steel fasteners and epoxy resin powder are applied inside and outside the shell to maximize rust prevention and prolong the service life.

The maximum allowable error of a low area (Q1 ≤ Q ＜ Q2) is ± 5%
when the water temperature is ≤ 30 ℃, the maximum allowable error in the high area (Q2 ≤ Q ≤ Q4) is ± 2%
When the water temperature is > 30 ℃, the maximum allowable error in the high area (Q2 ≤ Q ≤ Q4) is ± 3%
