Troubleshooting

This chapter provides detailed troubleshooting procedures and solutions for a variety of

common problems. The procedures described below are general in nature and are presented in

a “Quick Reference” style outline format.

We recommend that you perform the steps in order until the specic problem is solved. It may

not be necessary to complete all of the steps in a given procedure.

A. Leakage from Hydrometer Connection to Pipeline

• Inspect and tighten the couplings or ange bolts. Replace the coupling, bolts and nuts

as necessary.

• Apply Teon tape, or other similar material, to seal the connection.

• Inspect and replace gaskets as necessary.

• Inspect and clean the orice and associated gaskets (ow control applications only).

Replace as necessary.

B. No Electrical Output Signal From Hydrometer

• Inspect all cables and electrical connections. Repair or replace cables as necessary.

• Verify that the reed switch transducer is properly inserted into the register dial.

• Verify that the controller is functioning properly. If not, restart the controller and make

certain that your software is properly congured.

• Replace the reed switch transducer.

• Verify that the ow indicator on the meter dial is rotating.

C. The Controller Indicates Water is Not Flowing as Instructed

• Verify that the controller is functioning properly. If not, restart the controller and verify

that your software is properly congured.

• Move the 3-Way Selector to the “Open” position. Check to see if the controller shows

water ow. If so, this indicates that the solenoid is not functioning properly. Repair or

replace as necessary.

• Verify that the reed switch transducer is properly inserted into the register dial.

• Check all electrical connections. Replace cables as necessary.

• Verify that the ow indicator on the meter dial is rotating.

D. No Indication of Flow on Meter Dial

• Remove the register assembly as described on page 25. Place a small magnet on the

bottom of the register assembly and move it in a circular motion. This should cause the

ow indicator to rotate freely. If it does not, replace the register.

• Disassemble the hydrometer as described in Chapter 5.

• Clean or replace the strainer (1½” and 2” models only).

• Verify that the impeller rotates freely. If it does not, inspect the impeller, impeller shaft

and other related components. Replace as necessary.

• Inspect the diaphragm and o-rings. Replace as necessary.
