Is the Liquid Turbine Flow Meter Suitable for Purified Water Measuring?

Purified Water exhibits extremely poor conductivity—particularly at high purity levels—and therefore, conventional electromagnetic flowmeters cannot be used directly. 

In purified water measurement applications, the core advantages of liquid turbine flowmeters can be summarized as follows: while meeting requirements for high precision and rapid response, they maintain excellent cost-effectiveness and remain unaffected by the conductivity of the water.

They are generally regarded as a highly practical and efficient solution for pure water applications, particularly well-suited for industries such as semiconductor manufacturing, optics, pharmaceuticals, and food and beverages.

Rapid Response Speed

When flow rates fluctuate, turbine flow meters are capable of rapid tracking and response. This feature is particularly critical for applications requiring precise control of instantaneous flow—such as Batch Filling operations.

Compact Structure; Easy Installation and Maintenance

With their simple construction, small footprint, and lightweight design, turbine flowmeters offer exceptional ease of installation and maintenance. Furthermore, they exhibit low pressure loss and possess high flow capacity.

High Pressure and Corrosion Resistance

The wetted parts of turbine flowmeters can be fabricated from corrosion-resistant materials—such as 316L stainless steel —enabling them to withstand both high-pressure operating conditions and corrosive media. Simultaneously, this design prevents metal ion contamination of the fluid, thereby ensuring compliance with the stringent standards of industries such as pharmaceuticals.

Easy-to-Process Output Signals

The output typically consists of a stable pulse frequency signal. This signal features strong resistance to interference, facilitates long-distance transmission, and can be directly interfaced with automation control systems—such as PLCs and DCSs—for applications involving Quantitative Control and alarm monitoring.
