Remove and Install Optional Flow Meter

1. Remove the two mounting bolts (1) that hold spray bar valve support bracket to the platform.

2. Loosen the signal wire seal cap (2), and unscrew the weatherproof pickup housing (3) from the conduit adapter on the body of turbine flow meter (4).

3. Unscrew the swivel nut and unplug the signal wire connector from the magnetic pickup.

4. Remove the magnetic pickup from inside the conduit adapter on the meter body to avoid damaging the pickup while handling the meter.

5. Loosen the flange bolt nuts (5) enough to allow the pipe flanges (6) to move apart for flow meter clearance.

6. Completely remove one of the flange bolts (7) and its body centering ring (8).

NOTE: Be sure to note the direction-of-flow arrow on the side of the meter.

7. Remove the flow meter (4) from between the pipe flanges through the space created by the removed bolt.

8. Remove the flange gaskets (9).

NOTE: The following steps are for installation of the turbine flow meter.

9. Clean all upstream lines and the gasket surfaces before reinstallation of the meter.

10. Install the flange gaskets (9) and make sure the gaskets are properly aligned to help prevent damage to the gasket surfaces.

NOTE: Make sure the direction-of-flow arrow on the side of the meter and the conduit adapter is pointed in the proper direction as was noted at removal.

11. Position the flow meter (4) between the flanges (6), using the body centering rings (8) to align the meter body properly with the inside diameter of the flanges.

12. Install the removed bolt (7) and centering ring, then hand tighten the nuts until sure meter is centered and seated properly to the flange gaskets before torque is applied.

13. Tighten the flange bolt nuts (5) alternately and in even increments.

14. Apply a small amount of grease to the threads of the magnetic pickup.

15. Install the magnetic pickup into the flow meter by screwing it in hand tight, and then backing it out 1/4 turn. Tighten the locknut to maintain this position.

16. Plug the signal wire connector back into the magnetic pickup and tighten the swivel nut by hand until the connector is fully inserted into the magnetic pickup.

17. Thread weatherproof pickup housing (3) onto the conduit adapter on turbine flow meter (4) until hand tight, then tighten two full turns more.

18. Tighten the signal wire seal cap (2) and pump grease into grease fitting (10) until grease comes out of relief hole located opposite of grease fitting.

NOTE: All four bolts (11) may have to be temporarily loosened to align bracket holes to the platform holes.

19. Install the spray bar valve support bracket mounting bolts (1) back to the platform.


NOTICE

The flow meter must be filled with fluid before the pump is activated. Do not allow the fluid to slug meter or damage could occur to the rotor or to the bearings.


20. With the spray bar control valve closed and the inlet line to the pump raised above the outlet line, fill with water (thru inlet line) until level in outlet line is above the flow meter.

Disassemble and Assemble Optional Flow Meter

Start By:

a. remove turbine flow meter

1. Remove one of the bearing supports (1) by removing the three socket head capscrews from threaded holes (4) with a standard Allen wrench.


NOTICE

If a bearing support will not come out easily, try rotating the support while pulling. If necessary, a wooden dowel or brass rod may be inserted from the other end of the meter against the support, and the support tapped gently to free it. Use extreme caution in prying on the bearing supports since the internal parts may break or shatter. Soaking the meter in solvent may help free a bearing support.

Observe alignment marks (punch marks) on edge of the meter body and on the edge of each bearing support. These marks must be aligned in the same way when reassembling the meter.

Likewise, when a bearing support is removed from the meter body, note the direction-of-flow arrow on the bearing support. It is important that the upstream and downstream supports be installed in the proper ends of the meter body. The arrows on the supports must match the direction of the arrow on the exterior of the meter body.


2. Note the alignment marks, and pull bearing support (1) straight out of flow meter body (3).

3. Remove the rotor (2), noting direction-of-flow arrow (5) on the rotor.

NOTE: It should be possible to examine the other bearing support without removing it after the first support and the rotor have been removed.

4. If necessary, remove the second bearing support in the same manner as steps 1 and 2.

NOTE: The rotor and the two bearing supports are a matched set and come precalibrated from the factory.

5. Examine the carbide bearings in the bearing supports and the rotor shaft for wear or damage. If either bearing or the rotor shaft is worn or damaged and must be replaced, both bearing supports and the rotor must be replaced.

NOTE: The following steps are for assembly of the turbine flow meter.

6. Coat the outside diameter of each bearing support with grease to make installation and any subsequent disassembly easier. However, do not lubricate the rotor shaft or bearings.


NOTICE

Observe alignment marks (punch marks) on edge of the meter body and on the edge of each bearing support. These marks must be aligned in the same position when reassembling the meter for the meter to function properly and accurately.


7. Insert a bearing support (1) into flow meter body (3), making certain its direction-of-flow arrow corresponds to flow arrow (5) on the meter body exterior.

8. Align the index punch marks on the bearing support and the edge of the meter body, as was noted at disassembly.

9. Replace and tighten the retaining capscrews.

10. Stand the meter body on end, with the just installed bearing support at the bottom.

11. Insert rotor (4) into the bearing of installed bearing support, again making sure the arrow on the rotor points in the same direction as the meter body arrow.

12. Install the second bearing support (1) into the meter body and onto rotor shaft, and align the index marks before replacing the capscrews.

13. Tighten the capscrews, and then check that rotor spins freely.

14. If the rotor does not turn freely, the bearing support must be removed again and the cause determined.
