INSERTION FLOW SENSOR
(OPTION ISE)
Insertion Depth: 1/8th pipe inside diameter plus 3/4" (20 mm).
Orientation: Screw head marks the active face and should point
upstream ±5°.
Average Flow Rate: Before permanent tightening of swage lock fitting,
the probe can be inserted to variable depths to determine the flow
profile. Theoretical average flow occurs at 1/8 pipe diameter.
Installation Procedure: Install a 1" NPT Female Nipple on the Pipe.
Insert probe. Tighten swage lock until it just grips the Probe - then
tighten 3/4 of a turn. Do not use above 100 psi.
HIGH TEMPERATURE SENSOR
