Flow speed indicator circuit

Published:2011/8/26 3:12:00 Author:Jessie | Keyword: Flow speed, indicator | From:SeekIC

This circuit uses thermistors for load to measure flow. For a certain liquid medium, when its velocity is not the same, thermistors' cooling conditions are different neither, so itcan measure the liquid flow quantityor flow rate. In diagram, thermistors RH is put on the the arm of amplifier input bridge road, Bridge road unbalanced signal is detected by amplifierand become voltages, then it issent to the latter stage measurement amplifier or digital circuit to display.
