Dolomite,
a world leader in microfluidic design and manufacture, has entered a partnership
with Sensirion, a leading 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 and therefore precise flow rate control. The compact and lightweight
devices operate with total media isolation in combination with low internal
volume and no moving parts for an extremely 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 µl/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 excellent accuracy
as well as highly repeatable results and offset stability.
The unsurpassed CMOSens sensor technology from Sensirion combines a highly
precise thermal sensor element for exact temperature control with an A/D converter
circuit and digital signal processing to ensure an extremely sensitive response
is obtained. All measured data is fully-calibrated via an internal microcontroller.
Such outstanding results are obtained due to the integration of highly sensitive
thermo piles into an extremely fast, miniaturised thermal microsensor element.
With all of the precise signal-conditioning of a single CMOS chip, mass flow
measurements of the liquid flows on the µl and nl scale are made possible.
Furthermore, excellent chemical resistance and bio-compatibility make this compact
sensor ideal for a wide range of microfluidic applications.
These Microfluidic Flow Rate Sensors are available as part of a laboratory
kit, which includes all of the software and fittings required for immediate
use. The easy-to-use software enables simple capture, visualisation and exporting
of any measurement data. For high volume solutions highly efficient microsensors
based on the same technology are available.
