Dynasonics TFXP Series Transit Time Ultrasonic Flow Meter - Manual (Page 55)

I/O module bay number 1 is reserved exclusively for the ISO Data
Logger module.
The 200,000 event data logger/electronic stripchart recorder can be
configured to match most user applications. The logger stores time-
stamped, high resolution (16-bit) data at user selected intervals
ranging from 1 to 30,000 (8.33 hours) second(s).
The module can be carried in a shirt pocket back to the office and
plugged into an RS232 serial port via the module’s integral DB-9
connector. This eliminates the requirement to carry a computer to
the installation site. The data in the logger can also be accessed
without removing the module from the flow meter. Open the door of
the flow meter and connect the 9-pin cable between the data logger
and the PC’s RS232 serial communications port.
NOTE: Not all serial ports have the same load capabilities. If the
data logger is not accessible, the problem may be inadequate power
from the serial port. In these instances an external power supply,
available from Dynasonics, is required.
The logger is capable of storing up to 200,000 measurements. The
measurements are broken into 16 locations or pages with a
maximum number of data points per location of 30,000.
If each location (page) is filled to the maximum then 6 2/3 locations
would be used.
If all 16 locations are to be used, each location could hold a
maximum of 12,500 data points.
