2.2.3 Distance from Transmitter to Transducer
In general, the closer the transducer to the transmitter, the better the signals. All major cable
suppliers can supply up to 1640ft (500m) long transducer cable as per specifications.
2.2.4 Transducer Cables
The flowmeter requires twisted shielded cable for the transducers. We recommend to use the cable
supplied by the manufacture. If you want to do the transducer cabling by yourself, please consult
me in advance.
Try not route the transducer cable along with high current AC lines. Avoid strong interference
sources. Make sure the cables and cable connections are protected from weather and corrosive
conditions.
WARNING!
The transducers may have static charges accumulated during transportation. Before
connecting the transducers to the transmitter, please do discharge the transducer in a safe
area by shorting the centre conduction of the transducer cable connectors to the main
shield of the connector.
2.2.5. Input and output cable
Using standard twisted-pair wiring
2.2.6 Power Supply Wiring
The user normally selects the type of power supply when the order is placed. There are two types
of power supply options, 85-264VAC and 24VDC. User must make sure the power supply type of
your flowmeter matches the power source to which the flowmeter will be connected.
WARNING!
Be careful about the power supply type of your flowmeter and the power supply wiring!
Connecting to a wrong type power source or improper connection of line power could
damage the flowmeter. It may also cause hazardous voltage at enclosure, the transducer,
flow cell and associated piping.
Open the transmitter enclosure, on the lower left corner(refer to the figure in Appendix 9.1), you
