WarningsWarnings
• Conrm that U-clip retainer is installed and never remove the
U-clip retainer when pipe is under pressure—may result in
serious injury.
• Saddle bolts must be tightened evenly. Do not over tighten.
• Install security seals during installation if regulations require.
• Improper sealing of cables or cable glands will void warranty.
• Ensure proper grounding when required.
• Programming pipe ID, pipe insertion hole size and straight pipe
conguration is required for the meter to read.
• To prevent tampering or changes to the program, after initial
set-up, either enter a security pass-code, or remove the display
lid and place a security tab over one of the arrows before
installing the housing security seal.
Refer to instruction manual for further details.

BEFORE INSTALLING measure & record inside diameter (ID) of pipe.
Side (3 o’clock) and top
(12 o’clock) installations
are acceptable.
*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.
