Dwyer 熱式流量開關(guān) TDFS2系列產(chǎn)品信息

產(chǎn)品特色

? Better reliability and life expectancy than mechanical flow switches with no paddles or vanes to wear or break, no jams in the paddle movement, and no seals on movement assembly to wear or leak

? Not affected by empty pipe as it avoids overheating by actively heating above the process temperature and then cooling down to process temperature

? Low pressure drop; only needs to be inserted 10% into the flow (e.g. 1/8" for 3/4" schedule 40 pipe)
