Let’s discuss who is responsible for the measurement using back-blow instruments
Thread Content
Many back-pulse instruments are used in gasification units; could someone provide a specific explanation of the principle behind these back-pulse instruments?
What explanation? It’s because I’m afraid of congestion, that’s why I use backflow……
It’s still the back-and-forth conversion between p=ρgh
What standards must the pressure and flow rate of the backflow air meet in order not to affect the pressure being measured?
The pressure before the rotameter remains constant, and since the rotameter operates under a constant pressure difference, the pressure behind it is also constant. By this logic, the pressure remains constant from behind the rotameter all the way to the point where bubbles emerge from the liquid column. If the pressure is constant, then how can it be used to measure changes in the height of the liquid column?
