INTRODUCTION

General

The Model T650N Truck Totalizer provides flow totalization in any engineering unit. The totalized flow is displayed via
an accumulating 8 digit Liquid Crystal Display (LCD) electronic counter and an 8 digit resettable LCD.

Negatives previously associated with LCD’s - poor cold temperature performance, night clarity & condensation, which
is a byproduct of heaters, and incandescent lighting - have been eradicated with incorporation of a low temperature
coefficient LCD (-30
develop a precise, reliable totalizer.

Theory of Operation

The T650N initially amplifies & shapes the incoming pulses generated by the turbine’s response to flow. The amplified
pulse train is then scaled and divided to produce a totalized display in the desired engineering unit – gallons, liters,
pounds, SCF, m
sequence. A manual reset function is available if so desired.

Testing

A single switch “System Test” function enables maintenance personnel to quickly and effectively troubleshoot a system
failure, thereby reducing costly maintenance time. “System Test” provides a visual diagnostic indication of every
critical function of the T650N. With few exceptions, the system failure will be identified by the fault isolation LED’s of
the “System Test”.

Calibration

Field calibration is accomplished by incorporating a calibration factor based on the K-Factor of the turbine. A divider
switch provides a divisional increment of 10X from 1-10,000. The calibration factor is inserted using 4 BCD switches &
the 0-1 dip switch. The calibration factor range is .0001-1.9999. Verification of the electronics accuracy can be
accomplished by conventionally utilizing an external oscillator or by depressing the “System Test” switch which applies
a calibrated 500 Hz input signal to the system.

Temperature Compensation – Optional

A microprocessor based temperature compensation system designed to correct flow information based on product
temperature is available for use in the T650N. The Model 820 Temperature Compensator accommodates up to 8
different products (field selectable via a rotary switch) and accurately calculates the selected product density
acknowledging the non-linearity of the temperature probe and the product.

Installation of the Model 820 Temperature Compensator provides access to wireless I.R. communication for data
transfer to the Model SP824 portable ticket printer and provides an output for addition of a PCM-100 module for Pump
Control.

After market installation of temperature compensation requires minimal expertise and takes less than 15 minutes to
accomplish. By installing the 820 TC module, one connector to the 650 factoring board and the flip of a switch,
compensated totalization is accomplished.

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. If the packing
case is damaged, notify the local carrier at once regarding his liability. A report should be made to the distributor.
Carefully remove the equipment from the packing and inspect for damaged or missing parts.

Physical

The T650N Flow Converter should be mounted as practically as possible taking into account display visibility,
accessibility, etc. Ideally the T650N should be securely mounted using ONLY the supplied shock mounts on a stand
positioning the Flow Converter 12-18” above the deck, clear of overhead pipes and as remote from the pump motor as
possible. Although the T650N enclosure integrity is watertight at manufacture, adherence to these guidelines will
significantly enhance the trouble-free operation of the unit.

Electrical

The T650N is designed to operate on the 12 VDC power system of the transport and is “polarity insensitive”. Both the
+ and – power inputs should be obtained in the pump control box. To facilitate testing without having to activate the
entire pumping system, + power input should be derived from the unswitched 12V input to the pump control box.
Every effort should be made to keep the proximity of the Flow Converter’s input power leads to the pump motor’s
winding leads as isolated as practically possible within the pump control box. In the event a transport doesn’t have a
pump control box, as is the norm in CO
front of the trailer connected to the 12 VDC accessory or Light Circuit.

DO NOT ATTEMPT TO OBTAIN POWER BY SPLICING INTO THE LIGHT CIRCUIT LOCATED NEAR THE METER:
LINE DROPS AND FLUCTUATIONS MAY AFFECT THE UNIT’S OPERATION.

DO NOT CONNECT A JUMPER FROM THE T650N ENCLOSURE TO THE TRAILER CHASSIS AND DO NOT
REPLACE THE SHOCK MOUNTS WITH SOLID “LOOK ALIKES” AVAILABLE IN HARDWARE STORES; THEY
HAVE SOLID MOUNTING STUDS AND ARE NOT ISOLATING STUDS AS PROVIDED BY THE SPONSLER
COMPANY.

Signal

The standard T650N signal cable is a 2 wire shielded cable with an 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 adjust (R1) should be adjusted at the lowest expected flow rate. Turn R1 completely counterclockwise;
slowly adjust R1 clockwise until the display increments; then increase R1 slightly clockwise again. In the normal R1
position, the arrow indicator will be in the 11 o’clock position.

Calibration Factor

The Calibration Factor is derived by taking the reciprocal of the meter’s “K-Factor” (pulses per gallon or other
engineering unit).

It is desired that zero not be dialed as the first digit on the factor switches. The CF, in most cases, will start with at
least one zero. The divider switch (S7) on the factoring board will allow dividing by 1, 10, 100, 1000, or 10000 to move
the decimal the required digits.

“0-1” Function for Calibration:

The “0-1” function provides a greater degree of accuracy when totalization encompasses a large quantity such as SCF
produced in a 24 hour period.

Example #3: Assume a turbine flowmeter has a K-Factor of 79.58 pulses per SCF and a product demand of

520,000 SCF is the customer’s daily usage.
A delivery of 520,000 SCF = 41,381,600 total pulses (520,000 X 79.58).

Field Correction

To adjust the calibration factor to reflect the actual response of the turbine to the operating conditions, apply the
following formula:

C.F. = .4000

50/52 X .400 = New Calibration Factor
.9615 X .4000 = .3846
Insert .3846 into S3 – S6 respectively

In the above example .9615 denotes that the meter is operating 3.85% fast & multiplying the present calibration factor
(.4000) by the ratio of Actual Total: Meter Total (.9615) reduces the calibration factor 3.85%.

MODEL 820 TEMPERAT URE COMPENSATOR

Introduction

The Model 820 Temperature Compensator is a highly sophisticated electronic temperature compensation system
designed to correct flow information based on product temperature. Inserted between the signal source and recording
electronics, the temperature compensator will automatically add or subtract pulses from the pulse train based on
temperature of the product being delivered. The Model 820 is designed to accommodate up to 8 different products
(field selectable via a rotary switch) with the density and non-linearity of the temperature probe and each product being
acknowledged. Data transfer via wireless (IR) communications is available to print product selection, temperature,
correction factor and accumulated corrected total on the Model SP824 Portable Ticket Printer.

Theory of Operation

As product flows through the pipeline, a turbine located in the product spins and electrical pulses are generated and
sent to the temperature compensator. The number and frequency of these pulses corresponds to the amount of
product flow and the flow rate.

As the product in the pipeline heats or cools, the density and volume of the product change. When the volume of
product changes, the turbine spins faster or slower since the turbine flowmeter is a volumetric measuring device even
though the AMOUNT (measured by weight) of product is not changed. Model 820 performs its function first by
amplifying and conditioning signals from a pickup coil or other small signal device. The temperature of the product is
then read via an RTD temperature probe. Model 820 then adds or subtracts incoming pulses based on the
temperature/density of the product and the product’s correction curve.

As long as the product flowing past the temperature sensor is within range for the product, the temperature
compensator will automatically correct for the density of the product. If the product is not within the correct
temperature range, or the temperature probe fails, the compensator will turn on the alarm LED and modify the
temperature correction factor (TCF).

The TCF is modified based on the jumper installed at the jumper option block of the 820 (Ref. Drawing SCI-820­CONN-VOL-9-01 & Table “OPTION JUMPER” on the next page). If no jumper is installed, the correction factor will be
set for no compensation (TCF = 1.00). If the “B” jumper is installed, the 820 will stop accepting incoming pulses during
alarm condition, resulting in no count during an alarm condition. If the “C” jumper is installed, the compensator reverts
to ‘alarm’ temperature and corresponding TCF for the selected product (Ref the ‘Model 820 EPROM’ table for a listing
of products, temperature compensation range, and default alarm temperature).

The pump control output is used in conjunction with the PCM-100 module to disable the pump when the product is
above the proper temperature for delivery. If the 820 detects a complete temperature probe failure (temperature
reading above 200
after the temperature probe detects that the product is within the correct temperature range for delivery may be
activated by installing jumper ‘D’. This enabled delay allows the entire system to reach temperature before delivery is
allowed. Once the pump is enabled, the product temperature may go out of range for 10 seconds before the pump is
disabled. Once the pump is disabled, the initial delay time will be imposed before the pump is again enabled.
The delay times are based on the EPROM version installed on the Model 820 and the product selection. The following
table lists each version and the associated time delays (The EPROM installed on the 820 will be labeled with the
version).

System Setup and Installation

The Temperature Compensator has been calibrated for the RTD and tested in the factory. Once the unit is installed,
the product selector switch must be set to the correct position for the product being delivered.

The following table summarizes the option jumpers and their functions. NOTE: Only one jumper should be installed!

Calibration

To calibrate the unit, first set the product selector switch to position 8 (calibrate). Next replace the temperature probe
with a 100 ohm .1 resistor and observe the (-) and (+) LED’s on the PCB. If the (-) LED is on, turn the calibrate pot
clockwise until the LED goes off. If the (+) LED is on, turn the calibrate pot counterclockwise until the LED goes off.
Once both LED’s are off, the unit is calibrated properly and is ready for use.
