ASL1600

www.DataSheet4U.com PRELIMINARY DATA ASL1600 Media Isolated Liquid Mass Flow Meter − − − − − Totally non-invasive Maximum flows up to 4 ml/min Resolutions down to 100 nl/min Response time 30 ms RS-232 digital interface May 07 V0.7 ASL1600 Product Summary The ASL1600 Liquid Mass Flow Meter enables extremely fast and accurate measurements of ultra low liquid mass flows. This particularly small and light device operates with total media isolation, hardly any dead volume and no moving parts. The unique perform ance of this Swiss made device is based on Sensirion’s unsurpassed CMOSens® sensor technology which combines a high precision thermal sensor element with the amplification and A/D converter circuit and digital signal processing on one single CMOS chip. This results in superior resolution, fast response time and large dynamic range at low power consumption. All measurement data is fully calibrated and temperature compensated by means of an internal microcontroller. Excellent chemical resistance and bio-compatibility are ensured. The medium only gets in contact with the straight sensor capillary made of Duran®- (borosolicate glass 3.3), with the PEEK™-fittings and with Teflon® used as sealing material. Typical applications for this sensor include precise liquid mass flow and volume measurement for analytical instruments, medical devices, process control. The ASL1600 requires a supply voltage of 7…18 VDC and provides an RS-232 compliant digital interface. CMOSens® Technol...
