10. DISASSEMBLY AND INSPECTION
◎
Although it depends on individual operating conditions, periodic disassembly and
inspection should be performed at least once a year.
CAUTION: Because Ultra Oval is a precision industrial instrument, disassembly
and inspection should be performed indoors as a rule. If it is desired to
disassemble and inspect it as installed in the field, an important precaution
to remember is to reduce the internal pressure of the piping assembly to a
safe level, shut off valves upstream and downstream of the meter fully, drain
the piping assembly and then place a suitable fluid receptacle directly below
the Ultra Oval. Exercise care to keep individual members disassembled free
from grit and dust.
CAUTION: If the meter is of externally powered type, be sure to turn off power to the
register before you disassemble.

Meter Body Inspection
◆
Complaint and possible cause: Process fluid will not run.
Jammed with scales, the Oval rotors fail to rotate, resulting
in an interrupted fluid flow.
