3.1 General
The electrical connection between the ultrasonic flow sensor and the signal converter is
established with one (single beam versions) or two (dual beam versions) MR 02 signal cable(s).
The ends of the coaxial cables are provided with SMB plugs. The signal cable is provided with the
system.
3.2 Cable marking
The coaxial transducer cables are marked at each end by yellow tubing with a black number of
subsequently 1.1 and 1.2 for a single-beam design and numbers 1.1, 1.2, 2.1 and 2.2 for a
double-beam design. The first number represents path, 1 (single-beam) or 2 (double-beam) and
the second the position of the transducer of that path (1 or 2). The marking of the SMB
receptacles in the connection box is identical to that of the transducers cables (1.1, 1.2, ...).
