Blue-White Sonic-Pro S4 Ultrasonic Flowmeters - Manual (Page 6)

Transducer A Transducer B
The meter must be powered by 15 to 28 volts DC. Depending on the model ordered, an
AC/DC plug-in transformer may have been be supplied for this purpose. See the diagram
below for wiring of output signals, communications signals and process control relays.
The transducer cable length is factory fixed. Do not attempt to modify the length of these
cables. Various cable lengths are available from the factory. Contact the factory if you need
assistance.
Shielded cable is recommended for signal output connections.

The Sonic-Pro SPU wiring compartment is equipped with:
Ÿ Three liquid-tight cable gland connectors for cable diameter from .200 to .394 inches (5.1
to 10.0 mm).
Ÿ Two liquid-tight cable gland connectors cable for diameters from .118 to .255 inches (3.0 to
6.5 mm).
Ÿ One communications cable liquid-tight cable gland grommet for cable diameters from .190
to .205 inches. It is provided for any one of the following cable types:
Ethernet Cable
RS-232 serial cable
Note that the blank grommet plug should be used when the communications cable grommet
is not required.
