Location of Magnetic Switches
Digital Display Calibration should be performed to assure accuracy.
The calibration mode is entered by the use of a “password”.
There are two magnetic switches, one located at each side of the display.
These switches are activated with the use of a magnet.
Switch activation is visually confirmed by the lighting of the closest decimal point on
the display to the switch.

the lowest pressure condition) activate the left switch and then the right switch.
The right-most bar will begin to flash, indicating the display is ready for the high set point

Paddlewheel Installation
The flow display includes a totaliz er function. A momentary switch (optional) is required to operate this feature . The display
will continuously monitor flow when the
unit has power and display the latest total
volume when the totalizer switch is
pressed. The total flow is cleared when
power is removed from the unit.

operation and accurate readings. Mount the transmitter in a location that is accessible for future maintenance and in an area where laminar (non-turb ulent) flow is
most likely to be maintained. Most problems with flowmeter accuracy and perf ormance can be traced to the location of the transmitter .
The hole size for the paddlewheel transmitter (PN102714) mount is 1-1/2”.
The hole size for the paddle wheel transmitter (PN101199) mount is 1-7/8”.

the pipe diameter after an elbow or other turbulence producing item is desirable
for a successful installation. T ry to locate the transmitter using the longest straight
section of pipe available. Minimal turbulence at the transmitter provides the most

Wiring
The Flowmeter system comes with a wiring harness that connects the transmitter to the display.
The OEM must supply power and ground to the digital displa y . Consideration
should be given to the conditions under which the displa y will have pow er.
The display is internally protected against short circuits, overvoltage and reverse
polarity , but standard installation procedures should provide f or circuit protection.
Maximum current used by the flowmeter is 1.5 Amps.

A momentary grounding switch can be added when the totalizer function is desired. This is connected to the display through the 8 pin mini-connector at pin 8.

Operation
The flowmeter displays the current flo w rate whenever the displa y has power and
the discharge is open. Range is 0 to 9995 GPM, LPM or IGPM as calibrated.
Totalizer
The display includes a totalizer function that displa ys the total amount of water
that has been flowed since the unit was turned on. This feature is enabled b y
grounding terminal number eight (8) of the display connector .
When in the totalizer mode, all decimal points will flash to indicate this mode.
While terminal number 8 is grounded, activating the left switch resets the totalizer
to zero (0).
The totalizer resets to zero whene ver pow er is removed from the displa y.
Multiply the reading on the display b y 100 (add two zeroes) for total flow.

Calibration
Calibration matches the display to the paddlewheel tr ansmitter installation and
signal for a given flo w rate.
A method of accurately determining flow should be used to calibrate the unit.
A smoothbore nozzle and a Pitot gauge is suitable.
Flowmeter calibration must be perf ormed with the discharge flow stabilized at the
desired calibration flow rate.
Establish and maintain the calibration flow rate f or a minimum of 10 seconds to
assure an accurate and stable reading. When the flow is stab le, enter the
flowmeter calibration mode.

The

a visible indication of Oxygen remaining and an audible warning when there
is less than 20% oxygen remaining. The audible warning is inactive whenever the pressure is below 50 PSI so that it will not sound when the supply is
turned off.
The display represents oxygen volume information in an easy to interpret
LED bargraph display as a percentage of maximum calibrated pressure. The
display includes a visual warning and an auxiliary warning alarm output.
When the relative volume of oxygen remaining reaches 25%, the bars will
begin to flash, and when the system pressure drops to 20%, the auxiliary
output will turn on. The alarm can be silenced with an alarm silence switch.
Once the alarm is silenced, it will remain silent until the unit is turned off and
then back on, and will reset whenever the volume of air exceeds 20%. When
the alarm is silenced, there will be an aler t chirp every fifteen (15) minutes to
remind the operator that the oxygen supply is low.

Calibration for Breathing Oxygen Gauge installations:
Empty Cylinder (Closed Valve)
With the oxygen bottle closed and the system purged, enter
the calibration password.
L L L R R R
The left (0%) bar will flash to indicate that you are ready to calibrate for an
empty system.
Activate the left switch followed by the right switch.
The right (100%) bar will flash to indicate that the display is ready to calibrate
for a full system.
Maximum Volume
With a full oxygen bottle and the system pressurized, actuate the
right switch and then the left switch.
NOTE:
Calibration is complete.
Calibration should be accomplished using an oxygen
cylinder filled to the locally established maximum pressure.

The tank level gauge has a bar traveling back and f orth across the display .
There is a problem with the pressure transducer (PN 102162) or wiring. At the
transducer connector , check for 5 VDC betw een pins A (+5 VDC) and pin B
(ground). These are sent from the display and m ust be of the correct polarity for
the transducer to function. Plug the connector into the transducer and check f or
voltage between Pin B (sensor ground) and pin C (sensor signal) at the trans-
ducer. With an empty tank, this voltage should be between 500 mV and 900 mV, if
it is not, replace the transducer . Check f or v oltage at the display betw een pin 6
(sensor ground) and pin 2 (signal). With an empty tank, this v oltage should be
between 500 mV and 900 mV. If it is not, check the wiring from the transducer to
the display. If the correct voltage is present at pin 2, replace the displa y.
The T ank Level Gauge does not change or calibrate.
There is a problem with the pressure transducer or wiring. At the transducer
connector, chec k for 5 VDC between pins A (+5 VDC) and pin B (ground). These
are sent from the display and must be of the correct polarity for the tr ansducer to
function. Plug the connector into the transducer and check f or voltage at the
display between pin 6 (sensor g round) and pin 2 (signal). With an empty tank, this
voltage should be between 500 mV and 900 mV. As the water le vel in the tank
increases, the voltage should increase. If it does not, then replace the transducer
If the voltage increases, and the displa y does not change, attempt to calibrate the
unit. If the calibration does not correct the problem, replace the display.
The Flow Meter does not read flow or calibrate.
Place the meter in raw mode L R L R L L. Does the meter read pulses, and do
they change with a flow increase or decrease? If they do , re-calibrate . If you do
not read pulses, then it is a wiring or paddlewheel problem. At the paddlewheel,
check for 12 VDC between pins A (ground) and pin B (+12 VDC). These are sent
from the display and must be of the correct polarity for the paddle wheel to func-
tion. Plug the connector into the paddlewheel and check f or pulses at the display
between pin 6 (sensor ground) and pin 7 (signal). If pulses are not present, then
check the paddlewheel orientation and the signal wire from the paddlewheel to pin
7 at the display. If e v erything checks out OK, replace the paddlewheel. If the
signal is present and the display does not read ra w pulses, replace the display.
