When installing a DMT152 transmitter with ISO or UNF thread, use a
sealing ring to achieve a tight installation. Three copper sealing rings are
provided with the transmitter, and more can be ordered from Vaisala.
Note that the sealing rings for ISO and UNF threads are different. See
section Spare Parts and Accessories on page 65.
NOTE
Do not use a sealing ring with the NPT thread. Instead, seal the thread
using PTFE tape or PTFE paste sealant.
