What are the advantages and disadvantages of these two types of pressure gauges? What are the benefits of the one with flanges?

Why are one of these two pressure gauges connected to a pressure tap, while the other uses a diaphragm?
1. This is a pressure transmitter, more precisely, a single-flange pressure transmitter. 2. I didn’t see two watches; there was only one. 3. This single-flange transmitter can be used to measure either pressure or liquid level; it’s impossible to tell from this image. But in any case, what is measured is the pressure signal. 4. Single-flange types are generally used to measure the pressure of relatively viscous, crystalline, corrosive, toxic, or hygienically sensitive media, or the liquid level in open containers.
