Preliminary Information as of November 2001

ASF1400 Product Summary

The ASF1400 Mass Flow Meter enables extremely

accurate bidirectional measurement of gas flow over four

orders of magnitude. Its leading performance is based

on SENSIRION鈥檚 unsurpassed CMOSens鈩?sensor

technology. With CMOSens鈩? the on-chip sensor

element forms an integrated whole with the amplification

and A/D converter circuit. 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.

Mounted in rugged, chemically inert PBT housing the

ASF1400 is suitable for a wide range of applications.

Such include mass flow metering for process control,

medical applications, heating ventilation and air

conditioning (HVAC) solutions, as well as gas flow

metrology.

The sensor housing provides two inlets for measuring

the gas flow and withstands overpressures of 2 bar (29

psi).

The ASF1400 requires a supply voltage of 7鈥?8Vdc

and provides an RS-232 and SPI compliant electrical

interface.
