TROUBLESHOOTING (cont.)
3. “Indicator tube is cracked or broken.”
If the glass indicator tube is cracked or broken replacement can be shipped usually within
24 hours after ordered. One of the advantages of the Babbitt gage is the glass is easily
replaced without taking the gage out of service or shutting down the process. To replace
the glass, loosen the two screws in the PVC or Teflon block located in the top or bottom
of the scale assembly, remove the block and slide out the broken glass. If the gage is
over 6 feet tall, it may be easier to remove the entire scale and channel by loosening the
pipe clamps and taking it off the gage. This will protect the glass when replacing it and
remounting it to the gage chamber.
4. “Level switches don’t trip properly.”
All level switches may be wires to trip on rising or falling level. After the switch is wired for
the desired action (see instructions in this manual), it is necessary to set the switch. This
is easily accomplished by passing the float either manually or by filling the gage chamber
till it passes the highest switch. This will trip the switch to the desired setting so it will
alarm properly with rise or fall of level.
