Here's my version with Tikz. There are some minor details that I simplified but I'd say it resembles your image enough. The only thing missing are the circles to symbolize the gas, but I don't think that'd be hard for you to replicate.
The command is as follows:
\flask[ <arrow direction> ]{ <position of the flask> }{ <pressure> }{ <text> };
The first argument is optional. If not specified, the arrow will go right. To make it go left add [arrL] in the position you see above, with square brackets. After the position of the picture, which is self-explanatory, we have pressure where you type the value for the manometer. It accepts the actual value, so if you type 500, it will show that. Of course, typing 130 will work too, as you can see below, or even 137. The last argument is the text near the arrow to name the gas.
