GEnERAL inFORMATiOn
The DL75 is a battery-powered data logger that can be used
with any SeaMetrics flowmeter. It stores pulses for weeks
or months, depending on the user-set frequency of read-
ing. Indicator lights on the unit flash to indicate when it is
functioning and when the battery is low.
Normal life of the 3.6 Vdc Lithium C-cell battery is ap-
proximately three years, depending on sampling interval.
When the battery light on the front of the logger begins to
blink, remove and replace the battery as soon as possible.
Logger data is non-volatile, and will be preserved during
battery change.
The DL75 can be factory-mounted on the meter or remotely
mounted. Housings are rugged cast aluminum, gasketed for
environmental protection.
When a DL75 logger is placed into operation, it is easily
set up in the field using a laptop computer. Data is also
retrieved from the DL75 by means of a laptop. One laptop
can be used to retrieve data from multiple loggers. Data can
be analyzed on the laptop or easily loaded onto a desktop
computer for analysis.
SeaMetrics FlowInspector software allows the downloading,
storing, viewing, graphing, charting and printing of data in
several formats. FlowInspector requires a PC with Windows
98, NT, 2000, or XP; CD-Rom drive; 800 x 600 screen reso-
lution; serial port or USB/serial adapter; and a SeaMetrics
DC3 data cable.
