Is a sight glass usually installed on a water seal tank?

Can it also be installed on the overflow tube? Which one is more common? O(∩_∩)O Thank you
I think it’s an overflow tube, because that’s the only one I’ve seen. :$
It’s best to install one, right on the overflow pipe. We don’t have sight glasses, but since the water used for the water seal is purified water and at a relatively high temperature, I once checked the temperature of the water pipe by touching it.
The purified water used for the water seal should also be at around 40ºC after cooling, I guess
It’s over 40 degrees right now. In the past, it used to be around 70 degrees all year round, with a maximum of 86 degrees.
Water can still be used as a water seal even if it’s not cooled; hot steam will keep coming out of the vent pipe
What’s the point of having a mirror? It will break in no time:victory::victory::victory::victory:
How can you know if water is overflowing without using a sight glass?

After reading the replies from higher floors, I would like to say one thing: we added DCS pressure indicators inside the tank roof back in 1998, and that was really great! -Nominal range of 1000~3000Pa, control water seal of -500~2000Pa. The basic principle is to compare the readings of the two pressure indicators; the one corresponding to the blocked inlet will fluctuate significantly with changes in temperature (when the pressure gauge tube is blocked, there is only a small enclosed space behind it, making it highly susceptible to changes in atmospheric temperature and direct sunlight). In such cases, it is necessary to clear the blockage promptly.
DCS pressure indication in the tank roof room: Should the pressure transmission signal come from the water seal tank or from the larger tank? The basic principle is to use two pressure indicators as a reference to each other – one on top of the large tank and one on top of the water seal tank?
The tank top – it’s all the tank top. The pressure at the inlet of the water seal tank is not necessarily the pressure at the top of the tank. It should be more reasonable on the top of the tank.
