Clamp-On Transducer Mounting Modes - Siemens SITRANS F FUH1010 Series Operating Instructions Manual

Section 3
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 equip-
ment, other Controlotron systems, or any type of ultrasonic equipment. You can run these
cables through a common 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.
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
transducer 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.

3.3.3 CLAMP-ON TRANSDUCER MOUNTING MODES

Controlotron clamp-on transducers support Direct or Reflect mounting modes. The computer
recommends 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 trans-
ducer type you purchased.
