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 func-
tioning 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
environmental 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 resolu-
tion; serial port or USB/serial adapter; and a Seametrics DC3
data cable. FlowInspector comes in versions compatible with
up to 4, up to 16, or 17+ dataloggers.

MOUNTING & CONNECTIONS
MOUNTING
There are three mounting congurations for a DL76: Meter
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gurations 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
operation 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.
