Impeller Assembly and Shaft Replacement

If you are replacing an existing Data Industrial sensor and have already calibrated your flow monitor/transmitter,

no calibration changes are necessary. For installation of a new flow monitor or for relocation of a sensor in a

new pipe size, please refer to the calibration instructions in flow monitor manual.

1) Depressurize pipe from which sensor is

to be removed.

2) Remove the clevis pin.

3) Remove the sensor from the tee.

4) Note the impeller blade orientation

relative to flow arrows. In order to

maintain proper calibration, the impeller

will have to be reinstalled in the same

manner with the impeller blades pointing

toward the flow source as indicated by

the flow arrows.

5) To remove the old impeller blade

assembly, push the old shaft out of the

sleeve with the new shaft (or small

diameter rod) just far enough to grab

the end with a pair of pliers and pull the

shaft completely out. The impeller assembly will now be free, and will drop out.

6) Inspect the shaft and bearings for wear, and replace as necessary.

7) Refer to Figure 1. To reinstall, position the impeller in the cavity oriented as in Step 4 so that the impeller

blades point into the flow direction. The flow direction arrow on the top of the sensor housing should point

downstream with the impeller blades pointing upstream.

8) Carefully push the shaft through the housing and impeller, taking care not to damage bearings. Make sure

that the shaft is inserted far enough so that it clears the housing on each side of the impeller housing.

NOTE: If shaft is not carefully installed, the bearing can be deformed, preventing free rotation.

9) Inspect the O-rings for damage and replace as necessary. Clean the O-rings and the sleeve and relubricate

with silicone grease from the packet provided, or use some other acceptable lubricant.

10) Install the sensor into the tee so the flow arrows points in the direction of the actual flow.

11) Install or replace the clevis pin.

13) This completes the replacement procedure. The system may now be repressurized and tested.
