To build a manometer at home, I used the following:
- 20″ clear vinyl tubing
- flat thick cardboard/wood plank for the structure
- couple zap straps/zip ties
- Some high viscosity fluid (I used 10W-40 engine oil)
Take the flat piece of cardboard/wood and make equidistant horizontal lines across, with your favourite sharpie.
Drill holes on sides, so that you can secure the clear vinyl tubing to this board using zip ties.
Center the vinyl tubing on the board, making a U-shape (loop) at the bottom, and strap it to the board.
Use a syringe or funnel to pour your choice of oil into the tubing, until it sits at the desired level.
I’m having trouble attaching images to this thread, however there are lot of examples on Google, check out some images for inspiration, and good luck!
