Clean all pipelines to remove dirt and scale before instal­
lation.
Apply a minimum amount of pipe compound to the male
threads of the fitting only.
Do Not use teflon tape as a
sealant. Start with the third thread back and work away
from the end of the fitting to avoid the possibility of
contaminating the transducer. Install the transducer in the
air line.
NOTES: Instrument quality air, per ISA Standards
D7.3-1981, is required. Use a filter to re­
move dirt and liquid in the air line ahead of
the transducer for correct performance. If
an air line lubricator is used, it MUST be
located downstream, beyond the trans­
ducer.
The user is responsible for insuring that the
environment in which the unit will be
installed, and the operating gas, are com­
patible with the materials in the trans-
