Precision flow sensing for every environment
Reliable flow measurement is essential for maintaining the integrity of your process, yet different environments demand specific material properties. This range of Equflow turbine sensors utilizes a high-precision infrared sensing principle to provide consistent, accurate data across three distinct material options: Stainless Steel, PFA, and PVDF. By offering these specialized materials within a single, modular platform, we ensure you can match the sensor to your specific fluid path—whether you require the rugged durability of industrial steel, the ultra-high purity of PFA for bioprocessing, or the chemical resistance of PVDF. This approach simplifies your workflow by providing a standard level of accuracy and performance, regardless of the complexity of your application or the nature of the fluids involved.
These turbine sensors are designed to provide consistent accuracy across a wide range of specialized applications:
- Diafiltration
- Tangential flow filtration
- Virus filtration
- Harvesting
- Fill and finish
- Perfusion
- Nano filtration
