Could someone post a photo of a Manometer sight glass setup from their MLT?

[REDACTED]

Hey folks! Last week I asked a question about manometers, grants, etc and got some great responses. I understand that a typical manometer setup involves a pair of sightglasses, but I can't actually picture how this works, nor find any photos to reference online. Would someone mind snapping a quick shot, or even doing a quick sketch? It would be a big help.

Thanks!

Saw this post a little bit ago and kept forgetting to take pics of my set up at work.
