POWER SUPPLY and OUTPUTS
Battery Power (standard) . The AG2000 is powered by a non-
rechargeable battery pack with a continuous lifespan of 1 year
and up to 3 years under typical use. Actual lifespan will vary
from application to application, depending on the duty cycle.
“Low Batt” will display when it is time to replace the battery
(see illustration at right). Replacement instructions come
with the custom battery pack available from your dealer or
Seametrics.
NOTE: Memory will not be lost during a battery change.
External Power (optional) . Where power is available, the
life of the battery pack can be indefinitely extended by the
addition of an external power input cable. When external
power is used, the batteries serve as backup in case of power
failure, keeping the meter reading out during an outage. The
display reads “P” to indicate that external power is in use (see
illustration at right).
When the display is reading numbers/letters but neither the
“Low Batt” or “P” symbol is displayed, the meter is functioning
normally under battery power (see illustration at right). When
the display is completely blank, the meter is not powered.
Solar Power (optional) . In most areas of the US, a 12-
volt, 5 watt solar power unit (panel, charge controller and
battery) should suffice to operate the meter. In this case, the
internal batteries will serve as backup and battery life will be
conserved.

Display Reading . There are two lines to the display, the
bottom line for flow rate and the top line for accumulated
total. Measurement units are pre-ordered and factory-set and
can be changed in the field only by an authorized individual.

Metal Pipe Installations. To equalize the electric potential of
the fluid, the meter, and the surrounding pipe, secure the flange
plates, factory-installed on equalization lug, to both pipe flanges
at one of the bolt holes. Be sure the lockwasher provided fits
between the pipe flange and the flange plate.

WARNING: ELECTRICAL SHOCK HAZARD
When the AG2000 is installed in a plastic piping
system, or when externally powered, it is very
important to ground the meter to avoid electri-
cal shock hazard. Failure to do so can result in
electrocution.
Plastic Pipe Installations. In plastic pipe it is not neces-
sary to use the equalization straps, but the meter must
be grounded to avoid electrical shock and electro- static
interference with meter function.
