Basic Menu (BSC)
The basic menu contains all of the configuration parameters necessary to make the transmitter operational.
Parameter Meaning Options Description
UNITS Measurement standard
ENGLSH (Inches)
METRIC (Millimeters)
The English/metric selection will also configure the transmitter to display sound speeds
in pipe materials and liquids as either feet per second (fps) or meters per second (mps),
respectively.
IMPORTANT: If the UNITS entry has been changed from ENGLSH to METRIC or from
METRIC to ENGLSH, the entry must be saved and the instrument reset (power cycled
or System Reset SYS RSET entered) in order for the transmitter to initiate the change in
operating units. Failure to save and reset the instrument will lead to improper transducer
spacing calculations and an instrument that may not measure properly.
ADDRESS
Modbus or BACnet
address
1…126
This address is for the EIA-485 port only. Ethernet addresses are set via the integrated
HTML application in the Ethernet Port. For transmitters ordered with a Modbus RTU
option, enter a value 1…126. For transmitters ordered with a BACnet MS/TP option, enter
a value 0…127. Each transmitter connected on the network must have a unique address
number assigned.
BAUD Baud rate of RS485
9600
14400
19200
38400
56000
57600
76800
BACNET ID BACnet device ID value 0…4194303 Applies to BACnet networks only.
XDCR MNT
Transducer mounting
method
V
W
Z
Selects the mounting orientation for the transducers based on pipe and liquid
characteristics. See “Transducer Installation” on page15 .
XDCR HZ
Transducer transmission
frequency
500 kHZ
1 MHZ
2 MHZ
Transducer transmission frequencies are specific to the type of transducer and the size
of pipe. In general the DTTL 500 kHz transducers are used for pipes greater than 24
inches (600 mm). DTTR, DTTN and DTTH 1 MHz transducers, are for intermediate sized
pipes between 2 inches (50 mm) and 24 inches (600 mm). The DTTS and DTTC, 2 MHz
transducers, are for pipe sizes between 1/2 inch (13 mm) and 2 inches (50 mm)
FLO DIR
Transducer flow
direction
FORWARD
REVERSE
Allows the change of the direction the transmitter assumes is forward. When mounting
transmitters with integral transducers, this feature allows upstream and downstream
transducers to be “electronically” reversed making upside down mounting of the display
unnecessary.
PIPE OD Pipe outside diameter
ENGLSH (Inches)
METRIC (Millimeters)
Enter the pipe outside diameter in inches if ENGLSH was selected as UNITS; in millimeters if
METRIC was selected.
Charts listing popular pipe sizes have been included in the Appendix of this manual.
Correct entries for pipe O.D. and pipe wall thickness are critical to obtaining accurate flow
measurement readings.
PIPE WT Pipe wall thickness
ENGLSH (Inches)
METRIC (Millimeters)
Enter the pipe wall thickness in inches if ENGLSH was selected as UNITS; in millimeters if
METRIC was selected.
See “North American Pipe Schedules” on page110 for charts listing popular pipe sizes.
Correct entries for pipe O.D. and pipe wall thickness are critical to obtaining accurate flow
measurement readings.
