Is an ultrasonic flowmeter a good option for low-flow?
Flowmeister is pleased to answer this question with a YES!
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, and resistant PFA material for the wetted area.
Making it the ideal solution for applications in chemical dosing, flow-reactors, pharmaceutical production, and high-tech systems with UPW cooling circuits.
Its straight flowpath offers several key advantages:
• Minimal pressure drop
• Reduced risk of vibration and turbulence
• Easy integration into compact systems

The most remarkable feature of Flowmax® 4000i is its exceptionally high turn-down ratio of 600:1 (!)
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.
Flowmax® 4000i — precision low-flow ultrasonic measurement with maximum flexibility.
