Without a legend, it’s impossible to tell; a slash inside a box usually indicates a filter.
Thank you all for your replies. Since the original image has no legend or explanations, one can only rely on experience to figure it out
This should be an access to SIS, an access to DCS
It should be the instrument connectors – one pressure gauge and one flow meter
Quick connector, auxiliary pipe outlet, used at the site for purging and discharge
