Dynasonics TFX Ultra Transit Time Flow Meters - Manual (Page 56)

OTE:
N
This address does not set the Modbus TCP/IP, EtherNet/IP, BACnet address. That is set via the web page interface that
is integrated into the Ethernet port.
OTE:
N
Do not confuse the MODBUS address with the device address as seen in the upper left-hand corner of the display.
The Device Addr is included for purposes of backward compatibility of first generation flow meter products. The
device address has no function and will not change when used with this flow meter family.
Transducer
Transducer Type selects the transducer that will be connected to the flow meter. Select the appropriate transducer type from
the drop-down list. This selection influences transducer spacing and flow meter performance, so it must be correct. If you are
unsure about the type of transducer to which the flow meter will be connected, consult the shipment packing list or call the
manufacturer for assistance.
OTE:
N
A change of transducer type will cause a system configuration error 1002: Sys Config Changed to occur. This error will
clear when the microprocessor is reset or power is cycled on the flow meter.
Transducer Mount selects the orientation of the transducers on the piping system. See TRANSDUCER INSTALLATION in
this manual and Table 2 for detailed information regarding transducer mounting modes for particular pipe and liquid
characteristics. Whenever transducer mount is changed, a download command and subsequent microprocessor reset or flow
meter power cycle must be conducted.

Transducer Frequency permits the meter to select a transmission frequency for the various types of transducers that can be
utilized. In general, the larger the pipe the slower the transmission frequency needs to be to attain a good signal.
