SYSTEM 1010BX APPLICATION NOTES
The 1010BX is an extremely versatile transit-time Interface Detector that operates with ei-
ther non-intrusive clamp-on, or in-line (non-wetted) transducers. The following application
guidelines will enable you to obtain the best service from this equipment.
System 1010BX 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 protect 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 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 assistance.

TO OBTAIN TECHNICAL ASSISTANCE
The meter's computer provides comprehensive diagnostics data. Using this data, our engi-
neers can analyze the system in relation to the application. Proper analysis will provide solu-
tions to virtually any application problem. For technical assistance, please contact your local
Siemens representative for expert help (www.siemens.com).

PIPE CONSIDERATIONS FOR CLAMP-ON TRANSDUCERS
Clamp-on flow transducers operate on any round pipe that conducts sound. Suitable pipe
materials include most metals, plastics, glass and mandrel wound FRP. Pipes with a fine
grain structure (e.g., carbon and stainless steel) conduct sound more freely than cast iron,
ductile iron or copper pipes. Nevertheless, all are usually acceptable. Unsuitable pipes in-
clude concrete or other non-homogeneous materials. Pipe liners are acceptable if they are
sonically conductive and bonded solidly to the inner wall of the pipe. The system operates
successfully on pipes with cement liners that are "spun" onto the pipe interior to exclude any
air bubbles. Pipes with smoothly applied bituminous and epoxy coatings are also acceptable.
Plastic liners are universally acceptable, if they are in intimate contact with the inner wall
and not merely slipped within the pipe.
5.2.1 PIPE DIMENSIONS
Controlotron manufactures transducer assemblies to service pipes from 0.25" to 360" in outer
diameter. During the transducer install procedure, the computer will recommend transducer
sizes based on the site data that you enter. Pipes with OD-to-Wall thickness (OD/W) ratios
greater than 10 to 1 are ideal applications. Operation on pipes with OD/W ratios of 7
to 1 (or less) are acceptable, but may exhibit reduced stability and linearity. Generally, high-
er OD/W ratios provide better stability. If a pipe has a low OD/W ratio, you should use the
smaller of the recommended transducer sizes (i.e., if the computer recommends two trans-
ducer sizes).
