Saddle Clamp Installation
Note: Ensure that the mounting location meets the requirements for uniform water ow and that there
is enough room for the saddle clamp, sensor, and connector to t.
1. Drill and deburr a 1-11/16" to 1-3/4" diameter hole at mounting location.
2. Clean pipe surface in area where saddle clamp gasket seal.
Note: The sensor housing is epoxied in the saddle clamp with the alignment tab in the correct position
and is not meant to be removed.
3. Place saddle clamp over hole with sensor housing centered.
4. Tighten saddle clamp nuts until the gasket makes a good tight seal.
5. Insert ow sensor into sensor housing. Align at spot on sensor rim with alignment tab and make sure
O-ring is in groove.
Note: The retainer cap is hand-tightened. There is an inside lip that stops the cap from turning when
it makes contact with the alignment tab. This provides the correct pressure to make the seal at the
O-ring. Make sure the ow sensor engages the alignment tab and does not rotate.
6. Install retainer cap and hand tighten.
7. Connect ow sensor cable. (Refer to Wiring Section.)
