Dynasonics 901 Series Enhanced Ultrasonic Flow Meter - Manual (Page 23)

Rev.
04/02 -22- D901/M
The ID key allows the entry of a pipe’s Internal Diameter.
The D901/M utilizes the I.D. constant to process
volumetric flow rates such as GPM (Gallons per Minute) or
LPM (Liters per Minute). The entry is made as either
inches or mm, dependent on whether the unit is
configured as U.S. units or Metric units.
Press the I.D. key from the ENTRY MODE. The display
will show
This is the present I.D. constant. Enter a new I.D. based
on information obtained from the pipe manufacturer, a
physical measurement or a pipe chart. Some common
pipe sizes and dimensions are located on a series of
charts located in the Appendix of this manual. The
acceptable input range for the I.D. constant is shown in
Table 3.
* Pipe sizes less than 1 inch [ 25 mm ] require a Small
Pipe Transducer.
Note: If a decimal value of less than 1 is to be entered,
enter 0 . X X . The zero must precede the decimal value.
Note: If an entered value is out of the acceptable range of
the instrument, an UNDER! or OVER! indication will be
displayed. The meter will not allow any other entries to be
made until a legitimate value is entered.
