WARNING!

The retaining nuts of paddlewheel sensors are not designed for
prolonged contact with aggressive substances. Strong acids,
caustic substances and solvents or their vapor may lead to failure
of the retaining nut, ejection of the sensor and loss of the process
fl uid with possibly serious consequences, such as damage to
equipment and serious personal injury. Retaining nuts that may
have been in contact with such substances, e.g. due to leakage
or spilling, must be replaced.

3. Sensor Mounting Position

• Horizontal pipe runs: Mount the sensor in the 45° position for best performance. Mounting in
the 0° position may encounter problems with air bubbles (pipe must be full). Do not mount on
the bottom of the pipe when sediments are present.

• Vertical pipe runs: Mount sensor in any orientation. Upward fl ow is preferred to ensure full pipe.

4. Standard Sensor Installation

• Lubricate O-rings with a non-petroleum based, viscous
lubricant (grease) compatible with the system.

• Using an alternating/twisting motion, lower the sensor into the
fi tting, making sure the installation arrows on the black cap are
pointing in the direction of fl ow, see Figure A.

• Engage one thread of the sensor cap then turn the sensor until
the alignment tab is seated in the fi tting notch. Hand tighten the
sensor cap. DO NOT use any tools on the sensor cap or the
cap threads and/or fi tting fl ange threads will be damaged, see
Figure B.

5. Sensor Wiring

Technical Notes

• Use 2-conductor shielded cable for cable extensions.

• Cable shield must be maintained through cable splice.

• Refer to your instrument manual for specifi c wiring details.

6. 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 fl ex the ear outward enough to remove one end of the rotor and pin.
DO NOT fl ex the ear any more than necessary! If it breaks, the sensor cannot be repaired.

• Install the new rotor by inserting one tip of the pin into the hole, then fl ex the opposite ear back

page 4 OMEGA Paddlewheel Flow Sensors

enough to slip rotor into place.

7. K-Factors

A K-Factor is the number of pulses a sensor will generate for each engineering unit of fl uid which passes the sensor. K-factors for

water are listed below in liters and U.S. gallons. For example, in a 1-inch PVC pipe, the self-powered paddlewheel generates 172.07
pulses per gallon of water passing the rotor. K-factors are listed for pipes up to 12 inches. For pipes over 12 inches, consult OMEGA.

Chemical Compatibility

OMEGA products are manufactured in a variety of wetted materials to suit various liquids and chemicals.

All plastic materials including typical piping types (PVC, PVDF, PP and PE) are more or less permeable to contained media, such as water or volatile
substances, including some acids. This effect is not related to porosity, but purely a matter of gas diffusion through the plastic. If the plastic material is
compatible with the medium according to the application guidelines, the permeation will not damage the plastic itself. However, if the plastic encloses
other sensitive components, as is the case with OMEGA plastic paddlewheel sensors, these components may be affected or damaged by the media
diffusing through the plastic body and rotor.

PVDF paddlewheel sensor failure when used in hot nitric acid applications has been reported. PVDF is known to allow for substantial permeation of
nitric acid constituents without being damaged itself. No clear guideline can be given here, since the damaging effect to the sensor is highly dependent
on temperature, pressure and concentration. Utilizing sensors in applications with aggressive substances is possible. On special request OMEGA can
provide sensors with a different internal resin encapsulation (potting) that will delay the damaging effect of acids to the sensors. For all Special Product
inquiries or to place an order, please contact OMEGA.
