Positioning
Choose a position that will ensure a full pipe.
Choose a position that will minimize flow distortion.
Upstream straight pipe is selected during initial setup. Upstream options are
5X or 10X the diameter and are based on the amount of straight pipe available
in either new or propeller meter replacement installation. Downstream straight
pipe requirement is 2X the diameter. See programming setup for details.
Side (3 o’clock) and top (12 o’clock) installations are acceptable.
BEFORE INSTALLING measure & record inside diameter (ID) of pipe.
-
Clean the mounting surface, remove any roughness from the area and cut a 1.75″ hole into pipe. Place gasket centered over pipe opening.
-
Place saddle top over gasket.
-
Make sure saddle top covers entire gasket.
-
Place the saddle clamps under the pipe and align with the clamp guides on the saddle top.
-
Place saddle plates over saddle clamp threads. Attach nuts and tighten as shown below. Torque to 75 ft-lb in cross pattern.
