If you're looking for inexpensive and accurate, purchase a length of clear plastic tubing at your favorite hardware store and make a water manometer. A small amount of food coloring makes it easier for the old eyes to see . I also use mine to check PVC valve function on automobile engines .

I believe you can also use a gauge from a blood pressure cuff.

I think that would only give you pressure though.

Something like this.

Of course, you don't need the balloon thing.

Something like that but I don't feel successful unless I've used duct tape to hold the two tubes side by side and maybe guess for anything under 2" differential, but graduate to a tape measure for longer distances. I'm poor and mine must double as a drip irrigation tube in the dry arid climate when not doing manometer duty so it doesn't get attached to anything.

I don't make wine.

The static pressure in any of your ducts will be less the 1". Hopefully less then .3", an inclined manometer works better then just a straight up and down one.
