5.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 application guidelines to obtain the best service from this equipment.

System 1010 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 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 this can usually also reveal an appropriate remedy. Should this still present a problem, call us for technical assistance.

5.1TO 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 request help via e-mail by contacting the Siemens Technical Service Group at TSG.ultrasonicflow@siemens.com. The meter’s computer provides comprehensive diagnostics data. Using this data, our Engineers can analyze the system in relation to the application in detail. Proper analysis will provide solutions to virtually any application problem.

5.2CONSIDERATIONS 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 selection, use of the cor- rect clamp-on transducer or flow tube configuration, and paying close attention to installation instruc- tions. Such judicious use implies expert equipment knowledge and experience, plus a thorough under- standing of flow conditions.

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 the transducers or flow tube in strict accordance with the published in- structions. 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 require- ments. We recommend that all potential installers for critical applications participate in our training programs. Another alternative is to commission our trained professionals to start-up the system for you.
