The flow vanes that ApC2Kp mentions is basically what I have in mind, but I do not believe that I need them to run down the whole 1.5-3m long rotating drum. I thought the first 300-500mm should be enough. Air content varies from 2-7% at 200-300 l/s or 14-76 m3/h at atm. We however vacuum...

How much residence time is needed is a good question. The unit is used in the paper industry on flows with different levels of fiber and mineral contents as well as different chemicals. Currently the retention time is <1 second at 300 lpm (4,750 GPM). There may be some misunderstanding. The...

We are trying to design an impeller which takes flow from a full pipe (DN250) and forces it in to a rotational motion. The flow leaving the impeller proceeds axially in a 400mm diameter rotating drum. This is actually a “water ring” with an air column in the middle. This means that the flow in...

nbucska, We would like to measure the thickness externally. For light, we would need a window. The process flow is basically water, but there is a small anoumt of wood fiber and other particals that would destroy the window. MVD, Thanks again for your comments. Concerning the load cell, I...

Our device actual is a centrifuge, but with continuous flow through it. We want to know the water level, because air removal efficiency is dependant on how thick the water ring is. Too large or too small a thickness and the air removal efficiency goes down. The rotating pressure sensor's...

Our device is called a POMp and is used for removing air from process water. The thickness we wish to meassure is not a pond but the thickness of a water ring inside the rotating drum. It is basically 3 concentric cylinders. The outer is a 316L stainless steel drum, the second being a water...

We have a device which has a 400mm diameter drum rotating from 400-800 rpm. Inside the drum there is a water ring, which thickness varies depending on flow rate, drum rotational speed and pressure. We have measured the thickness of this ring (actually the air column) with a capacitive type...
