SYSTEM 1010 APPLICATION NOTES
System 1010 is an extremely versatile transit-time flowmeter that operates with either non-
intrusive clamp-on or in-line (non-wetted) flow transducers. Please review the following ap-
plication guidelines to obtain the best service from this equipment.
System 1010 provides a simple menu-driven interface for site programming. During the in-
stallation procedure, you tell the system what you need it to do. It will then verify the pipe
and liquid conditions, and based on your selections, optimize its operation automatically.
However, the system cannot protect itself from critical data entry errors that you input. Its
performance depends on the accuracy of the information that you provide it.
For normal operation, the flow computer only needs a receive signal of sufficient amplitude to
activate its automatic gain controlled detection circuits. Severely adverse application condi-
tions may reduce system performance, or cause apparent operational failures. Finding the
culprit that caused this can usually also reveal an appropriate remedy. Should this still present
a problem, call us for technical assistance.

TO OBTAIN TECHNICAL ASSISTANCE
Our Technical Service Group provides assistance upon request. You can obtain toll-free
assistance from 8:30 until 5:00 o’clock EST by calling 800-275-8480. In addition, you can re-
quest help via e-mail by contacting the Technical Service Group at [email protected].
The meter’s computer provides comprehensive diagnostics data. Using this data, our Engi-
neers can analyze the system in relation to the application in detail. Proper analysis will
provide solutions to virtually any application problem.

CONSIDERATIONS FOR CRITICAL APPLICATIONS
All flowmeters depend on site flow conditions and proper installation to achieve precise, critical
flow measurements. Unfavorable factors such as liquid non-homogeneity or stratification and
aeration/cavitation increase the possibility of reduced accuracy. This applies to all flowmeters,
regardless of their design, sophistication, expense and published intrinsic accuracy. These
factors become critical when applications involve custody transfer, tenant billing, and nuclear
or other safety-related flows.
System 1010 flowmeters automatically compensates for adverse flow conditions to achieve
extremely high accuracy. This requires following the instructions for proper equipment selec-
tion, use of the correct clamp-on transducer or flow tube configuration, and paying close at-
tention to installation instructions. Such judicious use implies expert equipment knowledge
and experience, plus a thorough understanding of flow conditions.
If your application requires critical measurement accuracy, it is not realistic to simply install
the flowmeter and expect optimum performance. Carefully review your piping configuration,
select the best mounting location and install the transducers or flow tube in strict accordance
with the published instructions. Even when the system is calibrated for enhanced precision at
a flow laboratory, this does not relieve you of the responsibility of adhering to the program-
ming instructions and installation requirements. We recommend that all potential installers
for critical applications participate in our training programs. Another alternative is to com-
mission our trained professionals to start-up the system for you.
