Setting Your Pulse Rate. The pulse rate is determined by
which sensor was ordered from the factory (single reed
switch, dual reed switch, or single Hall-effect) and by the dial
on which the magnet pointer is located. The pointer is set at
the factory, but can be changed in the field as follows.
In the table below: 1) Locate your meter size (Column 1);
2) Find your desired pulse rate (Column 2); 3) Note the magnet
pointer position (Column 3); 4) Move the magnet pointer to
the appropriate dial position (using the detailed instructions
below the table); 5) Use the appropriate Connection Diagram
(from Column 4) to wire the sensor to your remote device
(using diagrams on page 4).
Moving the Magnetic Pointer. Remove meter top and lens,
taking care not to lose the sealing ring. With fingers, lift the
magnet pointer off its shaft and remove the plain pointer from
the target dial. Reverse their positions and press them firmly
into place. Securely seat the sealing ring and replace the
lens, matching the tab on the lens to the notch on the meter
to align the sensor with the magnetic pointer dial. Thread the
meter top on and tighten.
†NOTE: A special magnet (available from the factor y) is re-
quired to achieve a rate of 4 pulses per gallon. It should be
placed on the x0.1 dial, with non-magnetic pointers on the
remaining dials. Otherwise, the procedure is the same.

Sample Set-Up. A 1” meter is shown with the magnet
pointer set at the x10 dial, with a pulse rate of 100 Gal-
lons per Pulse (that is, 10 increments on the x10 dial,
or 10x10=100 Gal/Pulse).

Reading Your Meter. The Total Flow that has passed
through your meter is read by starting at the top of the
register with the Six-Digit Totalizer, and then reading clock-
wise around the small dials. In the example below, the
Six-Digit Totalizer reads 13,800 (138 x 100), and the dials
read 60 (6 x 10), 2 (2 x 1), and .4 (4 x .1) respectively.
The Total Flow is 13,862.4 gallons.
[With the magnet pointer
on the x1 dial, the pulse
rate would be 10x1=10
Gal/Pulse. With the mag-
net pointer on the x0.1
dial, the pulse rate would
be 10x.1=1 Gal/Pulse.]
Special Configurations.
The 3/4” meter has a fourth dial,
as shown above. The x0.01 dial is
used for 20 P/G and 10 P/G rates.
Note: The 3/4” meter has a 5 digit
totalizer.
(NOTE: Disregard the color of the numbers on the totalizer when read-
ing your total.)
The “ones” digit is significant but the fact that it is red is not signifi-
cant.
