Fluigent’s expertise and industry-proven technology
Non-Invasive Flow Sensor for Industrial Integration[INIFS]
- New release
Our OEM non-invasive flow sensor (NIFS) is dedicated to flow rate monitoring and control. When combined with Fluigent pressure controllers, it allows pressure-based flow rate control without fluid contact, no liquid calibration is needed. It allows for accurate and repeatable measurements of a large range liquid flow rates bi-directionally.
- High performance
Use for all liquids, wide flow rate range
No liquid contact
- Plug and play
Straight forward set and use
High accuracy and precision
With Fluigent’s regulation control technology, the NIFS can measure flow rate with 5% accuracy.
As the non-invasive flow sensor is placed in the pneumatic path, it does not touch the liquid. It is suitable for applications where sterility is required. No cleaning is necessary.
Unlike traditional flowmeters, the NIFS functions independently of the liquid properties.
The sensor is compact and is recognized and integrated in your microfluidic setup by Fluigent software when connected.
An innovative, non-invasive flow sensor to overcome the limitations of current microfluidic flow meters
Effective microfluidic flow control requires accurate and reproducible flow rate measurement.
Fluigent’s cutting-edge technology enables users to monitor or control the flow rate in the fluidic path. Our contactless flow meter derives it from the air flow rate in the pneumatics at the outlet of our F-OEM / P-OEM / PX controllers. It is completely non-intrusive and eliminates potential contamination or clogging.

Fluigent provides lasting and highly stable flow rate control with the non-invasive flow sensor
Fluigent’s pressure regulation algorithm is based on physical equations and self-learning routines that offer several benefits:
- No overshoot/undershoot – allowing for a responsive, accurate, and stable flow rate
- Adaptable to three reservoir sizes
- Compatible with wide pressure and vacuum ranges
A wide range of flow rates and applications for the non-invasive flow sensor
For applications that require a contamination-free or sterile environment, working with several types of fluids, continuous operation with slow flow response time and flow rates ranging from 100 µL/min to 10 mL/min, we recommend our latest flow sensor, the NIFS. It consists of sensing elements and electronics integrated into a compact case. Standard M3 sized screws can be used for fixing the device.
Including cell culture under flow, blood/plasma perfusion, organ-on-a-chip, single/double emulsions, microparticles or cell-encapsulation.
Many biological experiments require disposable or sterilized components in the fluidic path. The use of NIFS is ideal for these applications.
Microfluidic droplet generation
As there is no calibration needed to manipulate several liquids, the NIFS saves time when users want to generate droplets, a process that involves different fluids (aqueous solutions, oil, surfactants, alcohols…).
Biochemical and molecular analysis
A sterile environment and lack of need for a calibration step are beneficial for drug, enzyme or food analysis through screening with droplet microfluidics.
