Introductions
WESDUN Instrument Turbine Flow Meter offers two accuracy classes, 0.5%R and 0.2%R. Its simple structure allows a small pressure loss and virtually no maintenance requirements.
The Thread Connection Turbine Flow Meter offers two types of converter options, Compact Type (Direct Mount) and Remote Type.
Our users can select the preferred converter type depending on the commissioning environment.
WESDUN Thread Connection Turbine flow meter is the most popular turbine product used in systems with small pipe sizes.

Features
- high-quality products with economical cost.
- applies to viscous fluids, non-conductive fluids, solvents, liquefied gases and high-pressure applications.
- high accuracy of 0.2% R and a wide range of applications to non-conductive liquids, such as fuel oil, ultra pure water and gasoline.
- wide turn down ratio of 20:1, combined with its mechanical designs enables the meter to operate reliably in both high and low flow rates and produce excellent repeatability as low as 0.05%.
- The Thread connection Turbine Flow Meter is known for its application to smaller pipe sizes. In the case of limited installation space, Thread connection Turbine Flow Meter is always preferred over Flanged connection and Tri-Clamp connection Turbine Meters.
