Flow Direction
FLOW DIR — Transducer Flow Direction Control (Choice)
FORWARD
REVERSE
Allows the change of the direction the meter assumes is forward. When mounting meters with integral transducers this
feature allows upstream and downstream transducers to be “electronically” reversed making upside down mounting of the
display unnecessary.
Transducer Frequency
XDCR HZ — Transducer Transmission Frequency (Choice)
500 kHZ (500 Kilohertz)
1 MHZ (1 Megahertz)
2 MHZ (2 Megahertz)
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). 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)
Pipe Outside Diameter
PIPE OD — Pipe Outside Diameter Entry (Value)
ENGLSH (Inches)
METRIC (Millimeters)
Enter the pipe outside diameter in inches if ENGLSH was selected as UNITS; in millimeters if METRIC was selected.
OTE:N 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 Wall Thickness
PIPE WT — Pipe Wall Thickness Entry (Value)
ENGLSH (Inches)
METRIC (Millimeters)
Enter the pipe wall thickness in inches if ENGLSH was selected as UNITS; in millimeters if METRIC was selected.
OTE:N 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.
