GENERAL INFORMATION
The DL76 is a battery-powered data logger that can be used
with any Seametrics owmeter. It stores pulses for up to 3 years,
depending on the user-selected frequency of reading. Indicator
lights on the unit ash to indicate when it is functioning and when
the battery is low.
The DL76 can be factory-mounted on the meter or remotely
mounted. Housings are rugged cast aluminum, gasketed for en-
vironmental protection.
When a DL76 logger is placed into operation, it is easily set up
using a laptop computer. Data is also retrieved from the DL76 by
means of a laptop and can be analyzed on the laptop or easily
loaded on a desktop computer for analysis.
FlowInspector software (ordered separately) is required for
the downloading, storing, viewing, graphing, charting and print-
ing of data in several formats.
FlowInspector requires a PC with Windows 98, NT, 2000, XP, Vista,
or Windows 7; CD-Rom drive; 800 x 600 screen resolution; serial
port or USB/serial adapter; and a Seametrics DC3 data cable. Flo-
wInspector comes in versions compatible with up to 4, up to 16,
or 17+ dataloggers.
Note: If ordering a wall mounted DL76 with a mechanical meter,
select the micropower -04 option.

MOUNTING & CONNECTIONS
MOUNTING
There are three mounting congurations for a DL76: Me-
ter mount for mechanical meters, meter mount for insertion
magmeters, and wall mount (DL76W). The meter mount models
match up to any Seametrics lower square housing. All congura-
tions can be factory-ordered or eld-installed. Converting from
one mounting conguration to another requires use of MK10 or
MK20 mounting kits.
Meter Mounting. Remove the four screws on the meter cover
with a 5/32” Allen wrench. After connecting the leads to their
respective terminals (see diagram), put the DL76 in place of the
meter cover and tighten the screws evenly. The gasket on the
DL76 should be visibly compressed by tightening all around.
OPERATION
Seametrics FlowInspector V.2 software is required for opera-
tion of the DL76. Please consult your FlowInspector manual for
instructions in loading the software onto your computer, setting
up your DL76 for use, downloading, storing, and analyzing your
data.
