Thread: Best options for Clearvue collection bin

Liquid column (manometer) from Wikipedia

The difference in fluid height in a liquid-column manometer is proportional to the pressure difference: {\displaystyle h={\frac {P_{a}-P_{o}}{g\rho }}}

Ring balance manometer

Liquid-column gauges consist of a column of liquid in a tube whose ends are exposed to different pressures. The column will rise or fall until its weight (a force applied due to gravity) is in equilibrium with the pressure differential between the two ends of the tube (a force applied due to fluid pressure). A very simple version is a U-shaped tube half-full of liquid, one side of which is connected to the region of interest while the reference pressure (which might be the atmospheric pressure or a vacuum) is applied to

The "local shed" has a manometer indicating 9" of water column when all blast gates are closed, I suspect there could a few leaks.
I like the idea of an automatic gate that opens when the water column rises to ?????

Using a formula BobL supplied some time ago, that 9” equates to a theoretical max CFM of 1228 in a system using 6” pipe.

No need to complicate things, close all gates and adjust the opening to close when one gate is opened.

Trying to find the best solution for the collection bin. I note that there is a mixture of solutions on the forum here from making your own, to wheelie bins, to those blue snap lock drums or steel 220L drums.

All input welcome.

As BobL said, make sure you have enough height to accommodate your proposed bin. Rather than using a standard bin and constraining yourself to its height, why not make your own bin(s) to optimise the room available? I made a box and lid from 19mm ply, glued and screwed. The interior joins were sealed with silicone sealant. The lid is secured with cam locks and sealed with 12mm x 25mm rubber strip from Clark Rubber. A handle on the front and rear wheels make it easy to move away.

Thanks for the info Mick. How do you empty your bin? Do you just roll this out back and dump it in the garden?

Cheers.

Most of the time I up-end it onto a heap about 5 metres from the dedicated and sound insulated dust extractor shed and the cattle eat it. It would probably be good mulch but the box is too heavy to empty directly into a barrow. The weight is the only downside of the box but using lighter ply could be risky without internal bracing.

I never use MDF owing to its toxicity and am still considering the fate of the full load of camphorwood shavings currently in the box for the same reason. I suspect they're bound for either the Oberon tip or the floor of one of the sheds to deter rodents.
