Every SMART ULTRA OVAL is fabricated and shipped from our factory under stringent quality control. In
order to maintain its design performance throughout the life of the meter, this manual offers the operator the
necessary installation, operation and maintenance information.
Be well familiar with these instructions before you place the meter in service and keep this manual at the field
location for ready reference.
The standard, high temperature-service, low temperature-service, and jacketed type meters all have in
common the same specifications described in this instruction manual except for some differences in the
jacketed type on its piping procedure and operating precautions. Be careful to observe the instructions given
with a reminder "See also page 5 for the jacketed type".
◆ About Meter Size Designation ◆
The size of OVAL positive-displacement flowmeters is basically identified by a two-digit code. For complete
details, see Section 7 PRODUCT CODE EXPLANATION.
