A compact and elegant gas flow meter

A compact and elegant gas flow meter

The µFlow is a compact and elegant instrument for measuring ultra-low gas flows with high precision. The µFlow has been designed for the online, real-time monitoring of all inert and slightly aggressive gases, over a wide detection range and for most indoor laboratory scale applications.

Suitable applications include biogas process studies, ethanol fermentation, dark fermentation for bio-hydrogen and gas leakage detection.

A low gas flow meter with zero labour requirements

A low gas flow meter with zero labour requirements

With the µFlow, gas flow measurements have never been so easy. The µFlow has an onboard LCD display for the real-time visualisation of normalised gas volume, flow rate and time, with a standard analogue output signal option for gas flow rate.

Since all gas flow measurements are taken online and in real-time, with the µFlow there are simply no labour requirements, thus freeing up time for more important activities.

An entirely new level of precision

An entirely new level of precision

The µFlow is a flow meter for ultra-low gas flow detection. Its design and highly precise calibration deliver highly precise measurement (CV≤ 1%) with a resolution of about 9 or 2 Nml.

The µFlow thus offers a level of precision that is unmatched, meeting the needs of the most demanding biogas/biofuel labs and low gas flow applications.

Normalisation of key measurements

Normalisation of key measurements

The µFlow offers real-time temperature and pressure compensation for the normalisation of gas flow rate and volume measurement at 0 degrees Celsius and 1 standard atmosphere (atm).

This feature will ensure that all gas flow measurements are accurate, and places the µFlow in a league of its own when compared to other low gas flow solutions.

Large detection range

Large detection range

The μFlow provides a large detection range, with high linearity from 4 to 850 ml/h for 2 ml flow cell and 20 to 4000 ml/h for 9 ml flow cell. This makes it highly suitable for most lab- and small pilot- scale applications. This flexibility means that the μFlow is an extremely versatile instrument for low gas flow measurements, with a high level of precision.

Overall, it is not only an instrument that is a must for biogas labs, but also any application where the precise measurement of inert and slightly aggressive gases is needed.

Gas flow and volume normalisation

Gas flow and volume normalisation

The µFlow automatically normalises gas flow and volume measurements with real-time temperature and pressure compensation. This allows for gas measurements and data presentation to be standardised and the impact of measurement conditions minimised.

The temperature and pressure of the gas are measured every time a flow cell opens, allowing the user to derive exact kinetic information compensated for any variation over time. The volumes are normalised to 0 °C and 1 atm.

Highly flexible gas flow meter

Highly flexible gas flow meter

The μFlow is a highly flexible low gas flow measurement device. It can be operated as a stand-alone instrument for a specific application or combined with other technologies, such as the 5 l and 10 l glass and steel bioreactors offered by Bioprocess Control. This provides an accurate simulation platform.

Its compact size in combination with a data acquisition system requires only a limited amount of space. This flexibility lets users conduct multiple gas flow and volume measurements with little effort and without wasting valuable bench space.

An integrated gas flow solution

An integrated gas flow solution

The µFlow is an integrated gas flow meter from several perspectives. The unit offers a standard signal output for automatic data acquisition and provides users with an embedded timer and reset button for easy logging of accumulated gas flow volume over a defined period of time.

The gas flow meter is also pre-calibrated to ensure measurement accuracy, offers a glass window for the viewing of flow cell movement, and has an adjustable foot to ensure the correct installation position for high precision measurements.

The µFlow truly offers an unmatched level of integration, which translates into a highly desirable instrument.

Designed for real-time monitoring

Designed for real-time monitoring

The µFlow gas flow meter has a computer-based software application that is specially designed for the monitoring and logging of any gas produced. It allows users to have a direct visualization of any variations in gas flow.

Users can set-up an experiment, monitor its progress and download results with little effort. Moreover, all data is in a format that allows for easy analysis.

The Settings feature of the µFlow software application allows users to define up to 8 channels. For each channel, the current flow rate is displayed, based upon the mean value over the last minute.

See your experiment in real-time

The Graph feature lets users see their experiment in real-time. Users can easily monitor the flow rate of each gas flow channel by selecting and viewing only those channels they wish to see. Moreover, gas flow measurements are normalized to 1 atm and 0 °C.

This flexibility and precision allows µFlow users to always know the status of an experiment, as well as the data being produced.

What Customers Say?

...the automation of the test minimises human errors, makes data collection more frequent than manual methods, and reduces operator time allowing more time for performing alternate tasks.

Associate Prof. Bernadette McCabe University of Southern Queensland, Australia

...µflow gas flow meter is a reliable standalone equipment. Check valves that come with µflow avoid water suction when there is low vacuum in reactors at early stage of experiment. The software of µflow data logger is really user friendly. It allows us to easily follow degradation process in real time.
