Flowmax® productline

Fast and reliable volumetric flow measurement

For industry, OEM, chemistry, life-science and food/gastro

The new-comer in low-flow: Flowmax® 4000i

Introducing the new Flowmax® 4000i ultrasonic flowmeter — engineered for precision liquid flow measurement in demanding industrial environments.

The Flowmax® 4000i combines advanced ultrasonic technology with an exceptionally compact inline design, making it the ideal solution for applications in the chemical industry, pharmaceutical production, and high-tech systems with UPW cooling circuits.

Its straight-through construction offers several key advantages:
• Minimal pressure drop
• Reduced risk of vibration and turbulence
• Easy integration into compact systems

The PFA-tubing suits a wide variety of liquids, such as UPW, WFI and chemicals.

Its straight-through construction offers several key advantages:
• Minimal pressure drop
• Reduced risk of vibration and turbulence
• Easy integration into compact systems

One of the most remarkable features of the Flowmax® 4000i is its exceptionally high turndown ratio. A single instrument can accurately cover a very wide measuring range while maintaining the high accuracy and repeatability that Flowmax® instruments are known for.

The sensor operates completely wear-free thanks to its non-contact ultrasonic measurement principle and the absence of moving parts. Conductive and non-conductive liquids can be measured reliably and with fast response times.

Every Flowmax® 4000i is individually tested before leaving the factory. Optional 3-point or 8-point calibration certificates are available for applications requiring documented traceability and enhanced accuracy assurance.


The Flowmax® family now covers:

  • 2.5 ml/minute to 900 l/minute
  • flowrate
  • temperature
  • liquid recognition
  • totalizer
  • gas-bubble detection
