ASL1430 Media Isolated Liquid Mass Flow Meter

   The ASL1430 Mass Flow Meter enables extremely fast and accurate measurement of ultra low liquid mass flows. This particularly small and light device operates with total media isolation and hardly any dead volume. Its leading performance is based on SENSIRION's unsurpassed CMOsens^® sensor technology which combines a high precision sensor element with the amplification and A/D converter circuit on one single CMOS chip. This results in superior resolution, fast response time and large dynamic range at lowest power consumption. All measurement data is fully calibrated and temperature compensated by means of an internal microcontroller. Excellent chemical resistance and bio-compatibility is ensured. The medium only gets in contact with PEEK. Typical applications for this sensor include precise mass flow and volume measurement for analytical instruments, medical devices, process control, as well as liquid handling applications. The sensor flow path provides two inlets for measuring the liquid flow and withstands fluid overpressures of 5 bar (72 psi) during operation. The ASL1430 requires a supply voltage of 7…18 VDC and provides an RS-232 compliant electrical interface.
