Avoid mounting the transducers on a section of pipe with any external scale. Remove all scale,
rust, loose paint, etc., from the location.

z
Do not mount the transducers on a surface aberration (pipe seam, etc.)
z
Do not mount transducers from different ultrasonic flowmeters on the same pipe. Also, do not run
the transducer cables in common bundles with cables from communication equipment, other Con-
trolotron systems, or any type of ultrasonic equipment. You can run these cables through a com-
mon conduit ONLY if they originate at the same flowmeter.

Never mount transducers under water, unless you order submersible units and you install them in
accordance with factory instructions.
accordance with factory instructions.
z
Never mount transducers on the top or bottom of a horizontal pipe. The best placement on a
horizontal pipe is either the nine o’clock or three o’clock position for Reflect Mode, or one trans-
ducer at nine o’clock and one transducer at three o’clock for Direct Mode. Mounting on a vertical
pipe is recommended only if flow is in the upward direction.

When mounting on a vertical pipe flowing in a downward direction make sure there is sufficient back
pressure in the system to maintain a full pipe.

3.1.3 CLAMP-ON TRANSDUCER MOUNTING MODES
Siemens clamp-on transducers support Direct or Reflect mounting modes. The flow computer recom-
mends a mounting mode after analyzing your pipe and liquid data entries. However, you can install
clamp-on transducers in the way that best suits your application and the transducer type you pur-
chased.
