Water Totalizer Notifier
The overall purpose of this device is to receive a
water meter input, and totalize the amount of water
that passes through the meter. When there is flow
through the water meter, the lights flash at a rate
that increases with the water flow rate. When the
This unit is to be powered using +12V DC. The
power input is a wire tail with a 2.5mm, center
positive barrel jack.
The totalizer has a battery backup. The battery
backup uses 3 AAA size batteries. The battery
holder is a part of the PCB assembly and can be
Water Meter
The totalizer keeps track of the gallons using a
water meter. The water meter is a turbine style
meter with a magnetic pickup that sends a pulse
to the electronics for every revolution of the
meter turbine. The meter turbine is removable
for inspection and cleaning. Make sure water is
bypassed or turned off when removing the meter for
maintenance. The meter has a three pin plug that
connects to the electronic board.
Power Monitoring and Battery Mode
The board monitors the 12V dc power and the
battery power. If there is a power failure and no
batteries are installed, the current totalizer value
will be saved to non-volatile memory. When power
is resumed, the totalizer count will resume from
when it had previously lost power.
The LEDs should shut off during battery mode. If
the totalizer is to the yellow or red state or if the
battery voltage gets low, the LEDs will flash on in
the appropriate colors for 0.125 seconds every 4
seconds. If the pushbutton is pressed in battery
mode, the LEDs will turn on for 4 seconds and then
return to battery mode.
total amount of water flowed reaches within 10%
of a pre-selected amount the totalizer turns yellow;
when the total amount reaches the pre-selected
amount, the totalizer turns red.
POWER
accessed by removing the lid to the filter. Battery
life will vary based on water flow when running on
battery mode and type of batteries used. With high
continuous flow, the batteries are expected to last
approximately 14 days. With no flow, the batteries
are expected to last approximately 6 months.
OPERATION
LEDs
Normal colors for the LEDs are Green, Yellow and
Red. Depending on the Totalizer value.
• Green = 0 – 90% of the totalizer maximum
• Yellow = 90 – 100% of the totalizer maximum
• Red >= 100% of the totalizer maximum
If there is flow, the LEDs should alternately turn
off in the following pattern: 1-2-3-2 (repeat).
The frequency that they turn off is linearly
correspondent to the flow rate being received from
the water meter. For every 1 revolution from the
meter, the LED pattern should be incriminated to
turn off the next LED. If there are no pulse edges for
2 seconds, all the LEDs will turn on solid.
If the battery is low, the middle LED (#2) will turn
White. The battery is checked only once an hour
to minimize the battery drain from checking the
voltage.
Pushbutton
The pushbutton allows for the totalizer to be reset.
To reset the totalizer, the user should press and hold
the button for 3 seconds. When the totalizer is reset
LEDs should flash green 3 times to confirm that it is
reset.
