6. Standard Sensor Installation

Figure A

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.

Figure B

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.

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.
