Pressure difference measurement of the packing device
Thread Content
As shown in the figure, a transparent glass tube filled with small balls, when subjected to N2 flow, creates a pressure difference at the inlet and outlet. When the pressure inside the glass tube is 0.1 MPa, a U-tube manometer is used to measure the pressure difference between the inlet and outlet. How to do it? ? ?
Isn’t it supposed to be to set pressure tapping points above and below the filler?
Are the two ends of the U-tube manometer connected directly to the top and bottom? Will this ensure a pressure of 0.1 MPa?
It’s not difficult, right? Just find a manufacturer and they can do it right away

Test points can be placed at the front and back of the outer glass tube and connected to a U-type level differential pressure gauge; pay attention to the gauge’s range to avoid exceeding it
Back then, when conducting experiments in the lab, the conditions were simple: a U-tube was used, filled with water, with rigid hoses attached to both ends of the U-tube, which were then connected to the points where the pressure difference was to be measured. (At that time, the glass containers were also custom-made, with ports for measuring pressure.) The U-tube was fixed to the wall, and grid paper with 1 cm squares on it was attached behind it, allowing me to calculate the pressure difference myself. Is this one also something you made yourself?
