GENERAL

The Model T575N i s a highly sophisticated electronic temperature compensated flow totalization system
specifically designed to handle the harsh conditions associated with liquid transports. Totalization is displayed via
a mot or driven V eeder-Root Met er R egister . Individual delivery data is displayed on eight 1/8” high figures. A
Veeder-Root zero start meter printer mechani cally prints the amou nt of the delivery on a 4 1/8” x 7 3/ 4” universal
met er ticket . Reset and print operations are manually actuated.

The input from a SPONSLER PRECISION TURBINE FLOWMETER or similar device is amplified, factored,
divided, temperature compensated, adjusted for the gearplate used and output through a motor driven circuit via a
SINGLE electronic circuit board. The Model T575N factoring/temperature compensation electronic modu le
accommodates th e temp er ature compen sation curves of up to eight di fferent products; field selectable via a rotary
switch. The RTD t emperat ure sensor is linearized automatically. C alibrati on of the Model T575N to provide
totalization in any engineering unit (gallons, liters, lbs., kg, etc.) is accomplished via four BCD factoring switches
and one BCD divider switch.

THEORY OF OPERAT ION

As product flows through a turbine flowmeter, rotor blades inside the flowmeter rotate through the m agneti c field of
the magnetic pickup coil generating electrical pulses through the pickup coil. The number and frequency of these
pu l ses correspond to the amount of product and the flow rate respectively.

The Model T575N Totalizer condit i ons these low amp l itude pulses from t he pick up co il. The amplified pulse s are
then factored, divided and, if equipped, temperature compensated. Factoring permits the displayed quantity to be
in any engineering unit desired. The flowmeter calibration factor that converts electron i c pulses to g al lons,
pou nds, liters, etc., is field adjustable. The overall factored pulses are translated to motor steps that drive the
Veeder-Root register. The Veeder-Root register displays a running account, final total, and accumulated total of
the product del ivery. The meter r egister drives the zero star t Veeder-Root printer which mechanical ly records and
prints d igital information. Th e zero start meter printer begins the coun t at zero and returns to zero when reset.
The pri nter total is the amount of the delivery. Print and reset operati ons are m anually activated.

Turbi ne flowmeters are volumetric devices; req uiring a means to CO M PENSATE for temperature related physical
changes of the product. As the product warms and cools, the density, as well as volume, changes while the
MAS S remains con stant . The Model T575N determines t he product temper ature via an R TD temper ature p r obe
located in t he delivery line and compensates for the corresponding temp er ature. As long as the product is within
the normal delivery tem peratu r e r ange of the product and there is no se nsor failure, the Model T575N will
automatica l ly correct for t he den sity of the produ ct. I f the product temperature i s not within the specified range or a
problem exists with the probe, the Model T575N will stop compensating and only factor the product. Whenever
the indicated t emperature is not within th e specified rang e, whether from a problem with the probe or a problem
with o n-board circuitry, th e COMPENSATED LE D located on the front of the unit will flash ind icating NO
COMPENS ATION and the ALARM LED on t he circuit board will illuminate. If jump er ‘A ’ is installed the unit will
not totalize when an alarm condition exists.

INPUT/OUTPUT M AXIMUM FREQUENCY

This unit is designed to operate with input frequencies up to 2000 Hz. When driving a Veeder-Root regi ster, t he
maximum output frequency after factoring and temperature compensation is 180 steps per second with 1:2
gearplate installed ( maximum count per minute is 1080) and 150 steps per second with 1:3 gearplate installed
(maximum count per m i nute i s 1351). Any att empt to output at a faster rate will cause pulses to go in to storage.
Up to 30,000 pulses can be put into storage. Stored pulses will be out put at the maximu m rate.

INSPECTION

All units are completely asse mbled, tested, and in spected at the factory pr i or to shipmen t. Up on receipt of the unit
a visual inspection should be conducted to detect any damage that may have occurred during shipment.

INSTALLATION

Physical

The T575N should be mounted as practically as possible taking into account display visibility, accessibility, etc.
Ideally, the T575N should be mounted on a stand, positioning the unit 12”-18” above the deck, clear of overhead
pipes and as remote from the pump motor as possible. The Model T575N MUST be securely mounted using
ONLY the SCI supplied shock mounts which have isolating studs.

Electrical

The T575N is designed to operate on the 12 VDC p ower system of t he transport and is “polarity insensitive”. B oth
+ and - power inputs should be obtained in the pump control box. To facilitate testing without activating th e entire
pumping system, + input power should be derived from the unswitched 12 VDC input to the pump control box.
Every effort should be made to keep the pr oximity of the totalizer’s input power leads to the pump motor windin g
leads as isolated as prac tically possible within the pump control box. In the event a transport does not have a
pump control box as is the norm in CO
12 VDC accessory or light circuit l ocated at the front of the t r ailer.

DO NOT attempt to obtain power by splicing into the light circuit located near the meter; line drops and
fluctuations may affect the unit operation .
DO NOT connect a jumper from the T575N en closure to the trailer ch assis.
DO NOT replace t he SCI shock mounts with solid ‘Look Alikes’ availab le in hardware stores: ‘Look Alikes’ have
solid mounting studs, not isolating studs as provided by SCI.

Cables

SIGNAL: P/N S-2F-2F-G-2S-20: The T575N standard signal cable is a 20’ 2 wire shielded cable with MS3102E
Connector termination which is the industry standard interface for 2-pole pickup coils. The shielding is
single-ended and should not be altered. Connect the shielded end (metal braided shield extends beyond
the end of the connector b ackshell) to the electronic unit mating connector (CO N 1).

POWER: P/N P-2M-SP-B-2U-20: The T575N standard power cable is a 2 wire cable with MS3106E12S-3P
connector t er mination for mating to the unit power connector (C ON4) and wire sp ade terminations for
connection to the 12 VDC power source. The unit i s ‘polarity insen sitive’ so that either wire m ay be
connected to + input.

PROBE: P/N R-3F-2M-G-2S-20: The T575N standard probe cable is a 20’ 2 wire shielded cable with
MS3106E12S-2PZ connector termination for mating to the unit probe connector (CON2) and a 3 pin
connector t er mination for mating with the RTD.

RTD Temperature Sensor

RTD Temper ature Sensor: Th e standard temperat ure supplied by SCI is a 2-wire 100Ω RTD with ‘rugged’
specification for use in transport systems. An aluminum head with MS3106E 3-pin connector term ination is
assembled to the R TD to facilitate cable co nnection in the system. The RTD has 1 /2-14 NPT threaded nipple for
installation in a mating coupling in the flowm eter outlet piping . A 7/8” Hex pl ane is located at the cen ter of the RTD
assembly for tighten ing the RTD into th e cou pling. DO NOT APPLY WRENCH ON THE PROBE HEAD
ASSEMBLY.

PRINTING/RESET

In printing operation, a ticket is inserted into the slot of the t i cket tr ay until it bot toms on the intern al stop.

1. Turn the prin t knob one complete clockwise revolution until a posit i ve stop is r eached. As the ticket tray
moves into position, the seal pin pierces the ticket, holding it in place. This initial printing is made with print
wheels at zero. Du r i ng this initial p r inting, a shut ter moves into pl ace covering the m eter register display wheels
and the in dividual wheels are set to a zero position. At completion of initial print /reset, the display wheels will read
all zeros, the shutter will rise to the normal operatin g position, and the ticke t will be imprinted with all zeros and
locked in place.

2. At the completion of the delivery, turn the knob in a clockwise direction one complete turn until the
posi tive stop is reached. Du r ing t his cycl e, the ticket tray returns to its origi nal posi tion and th e seal pin releases
the ticket.
NOTE: The meter r egister does not reset to zero at this time.

SENSITIVITY

If electrical n oi se is generated near the turb i ne or sig nal cab l e, it can overwhelm the real signal and cau se erratic
performance resulting in large errors. To prevent this condition, the sensitivity must be reduced. The sensitivity
adjustm ent should be made at th e lowest expect ed flowrate. Turn R15 completely cou nter-clockwise. With t he
low flow through the turbine, slowly adjust R15 clockwise until the totalizer i ncrem ents, then increase R 15 slightly
clockwise again. In the nominal R15 position, the arrow indicator will be in the 11:00 o’clock position

CALIBRATION

At the factory, Model T575N units are set for the gearplate used and calibrated for the engineering units and
product as speci fied by the customer. This ini tial calibration is based on a calibration factor (CF) derived from th e
reciprocal of the flowmet er “ K” factor (sensing elem ent constant) multiplied by 10 (electronics meter factor).
CF = (1/K) x10 = 10/K

Factor ing Switches SW 1-SW4 allow entry of a four digit Cali bration Factor.
The Divid er Switch ( SW 6) allows pr oper deci mal poi nt placement by dividing by 1, 10, 100, 1000 or 10000 so that

zero is not entered into th e M SD factor switch (SW1).

Step 2: Determine Divider required to move decimal point so t hat zero i s not entered into

FIELD CORRECTION

Sometimes, th e actual response of the turbine flowmeter t o the oper ating conditions will cause a small
CONSISTEN T error ( same per centage of error in several r uns). To correct this condition, the calibration factor can
be adjusted by using the following formula:

Meter t otal : 5 20

New CF = (.96154) x .4348
New CF = .41807

Insert 4181 into SW1-SW4 r espectively.

In the above example .96154 denotes that the meter is operating 3.85% fast and
multiplying t he present cali bration factor (.434 8) by the ratio of Actual total: Meter total

Calib r ation Factor - Change of Engineering Units
The Model T575N can be calibrated to read in most engineering units. A new K-Factor for the desired en gineering
un i t mu st be derived from the flowmeter K-Fact or ( pulse s per gal l on) and the conversion factor (liter s per gallon,
cubic meters per gallon, kilogr ams per gallon, etc.)

STEP 3: Round CF to four digits
STEP 4: Insert CF & DIVIDER

SW6 @ 0

Whenever a n ew factor is entered, a check should be m ade to ensure that the maximum count
speed would not be exceeded. The maximum count per minute with a 1:3 gearplate is 1351.
