Clean all pipelines to remove dirt and scale before installation. 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
contaminating the transducer. Install the transducer in the air line.
The inlet and outlet ports are labeled on the ends of the transducer.
Tighten connections securely. Avoid undersized fittings that will limit
the flow through the transducer and cause pressure drop down
stream.
Electric Connection
Make connections as shown in Figure 8.
Pneumatic Connection
NOTE:
Oil free air is required. Use a filter to remove dirt and
liquid in the air line ahead of the transducer. If an air
line lubricator is used, it MUST be located down-
stream to avoid interference with transducer perfor-
mance.
The user is responsible for insuring that the environ-
ment in which the unit will be installed and the
operating gas are compatible with the materials in the
transducer.
