INTRODUCTION
A. GENERAL
The model T350N-P Totalizer/Printer di s plays flow d irectly in engine ering unit s .
The model T350N-P utilizes the latest in circuitry design and components. The
circ uitry is microprocess or bas ed and perfor ms th e scaling and count i ng w ith only
one main circuit board.
The totalized flow is displayed on a liquid crystal display (LCD), and is printed on
standard calculator type thermal paper.
B. THEORY OF OPERATION
Model T350N-P is used in conjunction with frequency or pulse generating source
such as a turbine flowmeter or other pulse flow transducers. The totalized flow
disp l ay m ay b e c alibrated t o indicat e mos t an y uni t of vol u m e, gals., li ters, scf m. ,
etc. Standard units are factory-calibrated for a standard flowmeter in ga llons. If
additional calibration is necessary, the dividing factor may be changed by
adjustment of internal factoring switches located on the main circuit board.
The Model T350N-P dis p l ays total flow vi a an LC D dis play an d th er m al printin g
device. Printing of th e dis p layed tot al is accomplished by pus h in g the PRINT
switch. The printer will show a two-lin e m essage, product d eliver y, ti m e and
date, stating count, and finished count. There is a space provided for an
authorized signature. When the printer stops, the display will zero and be ready
to acc ept a new c ount. If th e PRIN T sw itc h is activat ed d ur i ng a d eli v ery, the
coun t will st op and the print er wi ll pri nt th e n ew inform ati on.

INSTALLATION
Inspection
All units are completely assembled, tested and inspected at the factory prior to
shipment. Upon receipt of the unit a visual inspection should be conducted to
detect any damage that may have occurred during shipment.
Physical
The T350N-P s hould be m oun t ed as practicall y as poss ible tak in g into acc oun t
disp l ay vis i bil ity, accessibi lit y, etc. Ideal ly the T350N -P should be securely
mounted using
ONLY
the supplied shock mounts on a stand positioning the unit
12-18” ab ove t h e d eck, clear of overhead pipes and as remote form the pump
mot or as pos s ib le. Adher ence to thes e gu id el ines will si gnificantly en hanc e the
trouble free operation of the unit.
Electrical
The T350N-P is designed to operate on the 12 VDC power system of the
transport and is “polarity insensitive”. Both the + and – power in puts s hould be
obtained in the pump control box. To facilitate testing without having to activate
the entire pumping system + input power should be derived from the unswitched
12 V input to the pump control box . Every effort should be ma de to keep the
T350N-P isolated as much as possible within the pump control box. In the event
transport doesn’t have a pump control box, as is the norm, 2 wires should be
routed to the trailer power junction box located at the front of the trailer. Do not
attempt to obtain power by splicing into the light circuit located near the
meter. Line drops and fluctuations may affect the operation. Additionally –
not connect a jumper from the T350N-P enclosure and the trailer
do
repl ace the ch oc k mou nts with so lid “Look a-likes”
chassis and do
not
available in hardware store. They have solid mounting studs and are not
isolating studs as provided by the Sponsler Company.
Signal
The standard T350N-P signal cable is a 2 wire shielded c abl e w ith a MS3102
connector termination which is the industry standard interface for 2 pole pickup
coils. The shielding is single ended and should not be altered.

CALIBRATION
Sensitivity
The Sensitivity adjusts (R1) should be adjusted at the lowest expected flow rate.
Turn R1 completely Counter-Clockwise then slowly adjust R1 Clockwise until the
display increments then increase R1 slightly Clockwise again. In the nominal R1
position the arrow indicator will be in the 11 o’clock position.
Calibrati on Fa ctor
The Calibration Factor is derived by taking the reciprocal of the meter’s “KFact or” (pulses per gal lon or other d esi red engin eering un it) .
C.F. =
Engineering Units
K-Factor
It is desired that ze ro not be dialed as the first digit on the factor switches. The
CF, in most cas es, will start with at l eas t on e z er o. The multip li er s wi tc h on th e
fact oring board wil l allow multipl yin g b y 1, 10, 10 0, 10 00, or 10000 to move t he
decimal the required digits.

1 10
2 100
3 1000
4 10000
Example 1: K-Factor = 230 pulses per gallon
Engin eering un it s des ir ed = gallons
C.F. = 1/K = 1/230 = .00434782
Multiplier = 100; S4=2,
Fac tor S3=4, S2 =3, S1= 4, S0=8
The electron ic acc uracy can be verifi ed i ncorporating t h e f ollow i ng f or mu la for a
timed tes t:
Total Displayed = Frequency X Time in seconds X C.F.
Example 2: C.F. = .004348
Time = 1 min = 60 seconds
Frequency = 500 Hz
Total = 50 0 X 6 0 X .004348
Total = 130.4 = 130

Decimal point = S5 = 1
Field Correction
To adjust the calibration factor to reflect the turbines actual response to the
operating conditions apply the following formula:
New Calibration Factor =
Actual Total
X Calibration Factor
Meter Total
Example #2:
Actual Total = 50
Meter Total = 52
C.F. = .004348
50/52 X .004348 = New Calibration Factor
.9615 X .004348 = .0041806
Insert 4181 into S3 – S0 respectively
In the ab ove e xam p le .9615 den otes that t h e m eter is op erating .38 5% fast and
multiplying the present cali bratio n factor (.004348) by the ratio of Actual Total:
Meter Total (.9615) reduces the calibration factor 3.85%.
Calibrati on Fa ctor – Change of Calibration Engineering Units
Assume that rather than gallons, liters are the desired engineering unit.

The self-test mode allows the totalizer’s microprocessor to per form internal tests
on the built-in RAM and ROM.
problem is suspected with the totalizer.
The self test feature should be used only when a
To start the self-test, first set the pre-
scale selector switch (S4) to position #9 (self test).
To fully test itself, the on-board computer must perform 257 different tests. As
each test is completed, A & B LED’s on the RLC113 PCB will flash. In order to
perform the complete test the leds must flash 257 times. Upon completion of the
257 test the LCD display will print ‘Eprom & RAM OK!’. Any other message
indicates an error. If no message app ears on th e LCD di splay, it is poss i ble that
the dis pl ay b i as c ont r ol is not ad jus t ed properly. To make the display and
background darker, adjust the display bias control fully counter-clockwise.
Adjusting this control clockwise will make the display and background lighter.
As long as the pre-scale selector s wit c h (S4) is in position #9, the microprocessor
will continue to test itself. Leaving the switc h in position #9 is a good way to
isolate any transitory problems.
NOTE: Be sure to set the pre-scale selector switch back to the correct position
for pr op er operation.

TEMPERATURE COMPENSATION (RLC131 option)
As product flows through the pipeline, a turbine located in the product spins and
electrical pulses are generated and sent to the totalizer. The number and
frequency of these pulses corresponds to the amount of product flow and the
flow rate.
As the product I the pipeli n e heats or cools , the dens it y and vol ume of the
product changes. When the volume of product changes, the turbine spins faster
or slower since the turbi n e fl ow m et er is a vol u m etr ic m eas uring d evice, even
though the AMOUNT (measured by weight) of product is not changed.
Temp er at ur e c om pens ation operates by r ead i ng th e t emp eratur e of t he produc t
and add in g or subtrac t i ng pu lses bas ed on t h e tem p erature and hence the
density of the product.
As long as the product flowing past the temperature sensor is within range of the
product, the temperature compensation module will automatically correct for the
density of the product. If the product is not within the correct temperature range,
or an elec tr ical problem exis ts wit h the temper at ur e probe, the comp e nsation
modu l e will n ot c omp ensat e for th e pr oduct and wil l si mp l y op er at e o n 1 1: 1 b asis
