Should a diaphragm shock-resistant pressure gauge be used for the on-site pressure gauge behind the 40% caustic soda pump?

A diaphragm is required, and the liquid-contacting parts need to be treated for corrosion resistance

Choose a flanged diaphragm pressure gauge; a model with a 316 material for the liquid contact part will suffice. At room temperature, 40% liquid caustic – 316 is sufficient; I checked the corrosion data manual and there are no issues
