Disposable Single Use Flowmeters

Committed to find the perfect fit

for your flow process

Disposable Single Use Flowmeters


Our disposable single use flowmeters are designed for a fast and easy exchange of the wetted parts. These solutions are very affordable as the housing, including sensor electronics, can be re-used and only the wetted parts will be exchanged.

Despite the term "disposable single use", these flowmeters are mechanically the same as the standard series flowmeters and are therefore suitable for long-term use, providing high accuracy. The disposable single use flowmeters are available in PVDF material (suitable for gamma irradation) or PFA material (chemical resistant). A complete validation package is also available.

Why Equflow?

  • Easy to use
  • Affordable
  • Over 20 years experience

How to use

Disposable Single Use Flowmeters

Working principle

  • Each flow tube has its own K-factor (calibration factor). The K-factor is the number of pulses per liter of liquid going through the flowmeter. Each flow tube is factory calibrated and the K-factor is listed on the label attached to every flow tube. Typical values for the K-factor can be found on the respective product pages.

  • Accuracies of 99% can be achieved with our PVDF flowmeters.

  • The repeatability of measurements is 99.85%.

  • In the medical devices industry, PVDF flowmeters are mostly used because of its suitability for sterilization with gamma irradiation.

    The medical devices industry includes various applications in which flow measurement and control is crucial. A dialysis system, for example, must be able to be cleaned quickly and easily after each run.

    This applies to all sorts of medical devices and equipment that process (body)liquids, like urine, blood and plasma. Avoiding contamination and infection is of the essence. Our flowmeters are also used in production processes, such as dosing and filling liquids in ampoules or bottles.

    The fast and easy exchange of the flow tubes reduces your process’ down-time to the minimum and avoids cross-contamination to guarantee safety of your patients.

  • PFA and PVDF flowmeters are both used in the water treatment industry, this depends on your application.

    Our flowmeters can support you in purifying water. We offer solutions for flow monitoring and dosing additives for your water treatment applications.

    Automated dosing of additives requires accurate volume control in which our flowmeters show an outstanding performance. A need for such operations can be found in treatment of cooling towers (addition of biocides for example), desalination (reverse osmosis), waste water systems, and filtration systems (utra-pure water production).

    The materials of construction we use for our flowmeters show high chemical resistance and hence can be used to clean and disinfect your water and filter systems perfectly.
