The basic principle is as follows: the pressure measured by the high-pressure tap and the low-pressure tap is transmitted to the high-pressure chamber and the low-pressure chamber inside the detection rod respectively. After averaging here, the \"average total pressure\" and \"average back pressure\" are obtained, which are transmitted to the high-pressure chamber and the low-pressure chamber of the differential pressure transmitter respectively, and the differential pressure signals of the two are converted into current signals, After the display instrument (or computer) calculation and processing, the fluid flow can be known<\/p>\n<h4>Installation position and direction<\/h4>\n<p>To meet the accuracy and repeatability of flow measurement, the correct mounting direction and straight pipe section are essential<br \/>\nConditions.
