SAFETY INSTRUCTIONS
1. Do not remove from pressurized lines.
2. Do not exceed maximum temperature/pressure specifications.
3. Do not install/service without following installation instructions (see sensor manual).
4. Wear safety goggles and faceshield during installation/service.
5. Do not alter product construction.
6. Failure to follow safety instructions could result in severe personal injury!
• Horizontal pipe runs: Mount sensor in the upright (0°) position for best overall performance.
Mount at a maximum of 45° when air bubbles are present. Do not mount on the bottom of the
pipe when sediments are present.
• Vertical pipe runs: Sensor must be mounted in lines with UPWARD flow only.

5. H-Dimensions
The plastic sensor insert in the Weldolet
fitting MUST be removed during the
welding process. When reinstalled, it is
important that the insert be threaded to
the proper height (“H” dimension).
1. Lubricate sensor O-rings with a silicone lubricant (e.g. GE silicone compound #G632 or
equivalent). Do not use petroleum based lubricant that will attack the O-rings.

direction of flow
2. Using a twisting motion, lower the sensor into the fitting, with installation arrows on the
black cap pointing in the direction of flow (Fig. A)
Fig. B
3. Engage one thread of the sensor cap then turn the sensor until the alignment tab is
seated in the fitting notch. Hand tighten the sensor cap. DO NOT use tools on the
sensor cap or the cap threads and/or fitting flange threads will be damaged (Fig. B)
7. K-Factors
The K-Factor is the number of pulses the sensor will generate for each engineering unit of fluid which passes. For example, in a 1 inch
PVC pipe, the paddlewheel generates 352.435 pulses per gallon of fluid passing the rotor. For pipes over 12 inch, consult OMEGA.

9. Rotor Replacement Procedure
• To remove the rotor, insert a small screwdriver between the rotor
and the ear of the sensor.
• Twist the screwdriver blade to flex the ear outward enough to
remove one end of the rotor and pin. DO NOT flex the ear any
more than necessary! If it breaks, the sensor cannot be repaired.
• Install the new rotor by inserting one ear into the hole, then flex
the opposite ear back enough to slip rotor into place.
