SYSTEM 1010P APPLICATION NOTES

The 1010P is an extremely versatile transit-time flowmeter that operates with either non-intrusive clamp-
on, or in-line (non-wetted) flow transducers. The following application guidelines will enable you to
obtain the best service from this equipment.
System 1010P provides a simple menu-driven interface for site programming. During the installation
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 pro-
tect itself from any 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 conditions may reduce
system performance, or cause apparent operational failures. Finding the culprit that caused them can
usually suggest an appropriate remedy. Should this still present a problem, call us for technical assis-
tance.

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 1010P flowmeters automatically compensate for adverse flow conditions to achieve their ex-
tremely high accuracy. Not closely following the instructions for proper equipment selection, use of the
correct clamp-on transducer or flow tube configuration, and paying close attention to installation in-
structions could adversely affect this accuracy. Judicious use requires expert equipment knowledge
and experience, plus a thorough understanding of flow conditions to achieve the high accuracy the
meter is designed to deliver.
If your application requires critical measurement accuracy, it is not realistic to simply install the flow-
meter and expect optimum performance. Carefully review your piping configuration, select the best
mounting location and install transducers or flow tube in strict accordance with the 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 programming instructions and installation requirements. We rec-
ommend that all potential installers on critical applications participate in our training programs. Another
alternative is to commission our trained professionals to start-up the system for you.
