Dolomite sensors measure ultra-low flow rates

Dolomite, a microfluidic design and manufacture company, has entered a partnership with Sensirion, a sensor manufacturer to offer a range of Microfluidic Flow Meters to measure ultra-low liquid flow rates in the laboratory.

This technology allows for sensor-actuator integration in Dolomite's range of microfluidic products, providing precise flow-rate control.

The compact, lightweight devices operate with total media isolation in combination with low internal volume and no moving parts for a fast and accurate performance.

Incorporating the innovative CMOSens technology, stable and precise results are obtained with every measurement.

With the ability to accurately measure flow rates from 0.05 to 4000 ul/min, and minimal energy consumption this technology provides a highly cost-effective measurement method.

The low-flow sensors are capable of operation at high pressures with high resolution within a large dynamic range to achieve accuracy as well as repeatable results and offset stability.

The CMOSens sensor technology from Sensirion combines a thermal sensor element for exact temperature control with an A/D converter circuit and digital signal processing to ensure a sensitive response is obtained.

All measured data is fully-calibrated via an internal microcontroller and thermo piles are integrated into a fast, miniaturised thermal microsensor element.

With the signal-conditioning of a single CMOS chip, mass-flow measurements of the liquid flows on the ul and nl scale are made possible.

Chemical resistance and bio-compatibility make the compact sensor suitable for a range of microfluidic applications.

Microfluidic Flow Rate Sensors are available as part of a laboratory kit, which includes all the software and fittings required for immediate use.

The software enables simple capture, visualisation and exporting of any measurement data.

For high-volume solutions, microsensors based on the same technology are available.
