Dwyer Instruments IEF Series Installation Instructions page 4

Sensor Alignment
A depth and flow alignment installation tool is provided to ensure proper depth insertion
and flow alignment. To set the insertion depth verify the alignment scale has not moved
from its original setting based on the alignment scale value set previously.
Loosen compression nut (4) to allow the shaft (3) freedom to travel up and down and
rotate inside the process collet (5).
Install Depth and Alignment Rods
1. Remove alignment rods from sides of alignment scale by sliding them out.
2. Insert the two rods into the alignment scale as shown.
FLOW ALIGNMENT ROD
3. Rotate the transmitter so the pipe alignment rod is parallel with the flow in the
pipe.
FLOW DIRECTION
4. Slide the shaft (3) down into the process collet (5) until the depth rod contacts
the pipe. If pipe insulation is present press the rod through the insulation.
a. Tighten the nut (4) to 15 ft.-lbs (20.3 N m)
b. Remove the flow alignment rod and loosen the thumbscrews to slide the
alignment tool up to allow removal of the depth alignment rod. Store both
rods in the storage slots on the sides of the alignment scale. Tighten
thumbscrews and leave alignment tool mounted on unit for storage.

GROUNDING
Metallic Pipe
For proper operation the instrument must be earth grounded.
Connect a ground wire to meter housing via the ground lug on the housing collet.
Connect the ground wire to a known earth ground.
If the pipe is grounded, connect the ground wire to the metal pipe using suitable
devices such as grounding clamps.
Non-Metallic Pipes
Connect a ground wire to the transmitter housing per the ground lug on the housing
collet.
Connect the ground wire to a known earth ground.
Ground the fluid to earth.
POWER SUPPLY
Choose a power supply with a voltage and current rating sufficient to meet the power
specifications under all operating conditions.
If the power supply is unregulated, make sure the output voltage remains within the
required voltage range under all power line conditions.
