描述 Description

The ASF1400 series Mass Flow Meter which enables extremely accurate bidirectional measurement of gas flow over four orders of magnitude. Its leading performance is based on SENSIRION's unsurpassed CMOSens? sensor technology. With CMOSens?, 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. The sensor housing provides two inlets for measuring the gas flow and withstands overpressures of 2bar (29psi).

簡介

ASF1400屬于傳感器變送器的流量傳感器。由制造生產(chǎn)的ASF1400流量傳感器該系列產(chǎn)品可用于測量或檢測水或空氣等流體的流量。較簡單的產(chǎn)品可提供流速是否超過某個定義值的二進制指示，而較復(fù)雜的產(chǎn)品則能夠提供可變輸出，由此可以將流體流量確定為單位時間的質(zhì)量/體積數(shù)量。在這兩種情況下，設(shè)備的性能都與工作流體的特性密切相關(guān)，并且介質(zhì)兼容性問題也是設(shè)備選擇和應(yīng)用中值得注意的問題。
