1. Location of Fitting
Recommended sensor upstream/
downstream mounting requirements.
2. Sensor Mounting Position
• 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. Do not alter product construction.
6. Failure to follow safety instructions could result in severe personal injury!
• Use 2-conductor shielded cable for cable extensions up to
300 m (1000 ft).
• Cable shield must be maintained through cable splice.
•+GF+SIGNET Intelek-Pro, use 2536 input card setting

7. K-Factors
The K-Factor is the number of pulses the sensor will generate for each engineering unit of fluid which passes. They are listed in U.S. gallons and
in liters. For example, in a 1 inch PVC pipe, the paddlewheel generates 352.435 pulses per gallon of fluid passing the rotor. K-Factors are
listed for pipes up to 12 inch. For pipes over 12 inch, consult your +GF+SIGNET distributor.

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).

6. Standard Sensor Installation
1. Lubricate the sensor O-rings with a silicone lubricant (e.g. GE silicone compound #G632 or
equivalent). Do not use any petroleum based lubricant that will attack the O-rings.
2. Using an alternating/twisting motion, lower the sensor into the fitting, making sure the
installation arrows on the black cap are pointing in the direction of flow, see Figure A.
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 any tools on the sensor cap or the
cap threads and/or fitting flange threads will be damaged, see Figure B.

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.
