The Dolomite Centre Ltd Part name Part number Microfluidic Flow Rate Sensor A (200 to 4000 µl/min) 3000238 Microfluidic Flow Rate Sensor A (40 to 1000 µl/min) 3000239 Microfluidic Flow Rate Sensor B (1 to 40 µl/min) 3000240 Microfluidic Flow Rate Sensor B (0.25 to 7 µl/min) 3000241 Microfluidic Flow Rate Sensor B (0.05 to 1.5 µl/min) 3000242 Description In partnership with Sensirion, Dolomite is able to offer a range of Microfluidic Flow Rate Sensors. The sensors enable extremely fast and accurate measurements of ultra low liquid flow rates. They are compact, lightweight devices that operate with total media isolation, low internal volume and no moving parts. The unsurpassed CMOSens ® sensor technology combines a high precision thermal sensor element, amplification, A/D converter circuit and digital signal processing on a single chip. All measurement data is fully calibrated and temperature compensated by means of an internal microcontroller. Excellent chemical resistance and bio-compatibility are also ensured. The sensors are provided in a laboratory kit that includes software and fittings required for immediate use. Microfluidic Flow Rate Sensor A Microfluidic Flow Rate Sensor B The laboratory kit, it includes: sensor, software, fluid fittings, international power supply and a data cable. Benefits • Extremely sensitive and fast response • Measures very low liquid flow rates • Low internal volume • Total media isolation • Compact and lightweight • High resolution and large dynamic range • High operating pressure • Low power consumption • Excellent chemical resistance and bio-compatibility Microfluidic Flow Rate Sensor_product datasheet
