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 specific 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 flange bolts. Replace the coupling, bolts and nuts
as necessary.
• Apply Teflon tape, or other similar material, to seal the connection.
• Inspect and replace gaskets as necessary.
• Inspect and clean the orifice and associated gaskets (flow 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 configured.
• Replace the reed switch transducer.
• Verify that the flow 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 configured.
• Move the 3-Way Selector to the “Open” position. Check to see if the controller shows
water flow. 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 flow 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
flow 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.
