2. GENERAL

Using the most advanced electronic tehcnologies, this digital instrument has been developed specifically for crude oil and heavy oil blend ratio measurement applications where accuracy is the prime requirement. In response to the flowrate, temperature, and blend ratio information arriving from the OVAL flowmeter, it converts the flowrate to the equivalent volume flowrate under standard conitions and totalizes the flow. An analog output and instant flowrate (corrected for meter error and temperature) output are additional provisions.

2.1 Features

(1) Changing the meter factor, ranges of temperature and blend proportions, liquid kind, density, or other

parameters, of the companion flowmeter is simple by keystrokes on the front-panel keypad.

(2) Built around a microprocessor, the instrument carries out calculations entirely in digital signal

processing circuits to achieve a high degree of accuracy and reliability.

(3) Variables, such as temperature and pressure, can be reviewed on command with the front panel

keypad, whether or not calculation is in progress.

(4) A nonvolatile memory (E2PROM) retains all parameters and variables. Variables are resettable

following a power cycle or reset if so configured.

4. WIRING

(See the "Wiring Guidelines" in the instruction manual of the companion pulse generator.)

4.1 Field Wiring Cables

(1) Use electrostatically shielded, polyethylene insulated, vinyl sheathed control cables (CEVS, 1.25 to 2

mm, 2-conductor or 3-conductor), or equivalent, for input signal cables from the flowmeter. For output signal cables, use insulated vinyl sheathed cables (CVV, CVS ... JIS C 3401).

(2) Ground the end of shield wire to "G" terminal of the instrument. At the sensor end, leave the end of

shield wire unconnected.

4.2 Wiring Connections

(1) Field wiring through a conduit is recommended.

NOTE: In routing field wiring, use a separate conduit for power cable from other signal cables to

eliminate the possibility of stray current pickup.

(2) Separate field wiring from other power lines and power circuits to minimize the possibility of inductive

interference.

(3) Using crimp-type lugs for wiring, ensure good electrical connections.

Terminals are found on the back of the instrument (Fig. 4.1).

4.3 Description of Terminal Blocks for External Connections

Terminal blocks for external connections (TB1, TB2 and TB3) are found on the back of the instrument as shown in Fig. 4.1. Terminal identification appears in Table 4.1 while terminal connections appear in Table 4.2.

6. INTERNAL COMPONENTS AND FUNCTIONS

6.1 Front Panel

6.1.1 Display

The display is a 128 × 128-dot multiple function display capable of showing the data, units of measure, error messages, and other information at the same time. (The display is backlighted.)

6.1.2 On-Screen Menu Items

The units of measurement vary with configuration. Their selection is made in the SET mode. Available menu items are:

(1) Uncorrected total flow (TOTAL COUNT)

Incoming flow pulses are calibrated for meter error, integrated before correction for temperature, and the obtained totalized flow is indicated. Resolution, or the minimum unit of measurement, which varies with customer specifications, is set up with front-panel keys. This unit automatically becomes identical with the output pulse unit. While the total flow is retained irrespective of power cycling, it is resettable to zero following a power cycle if so configured in the SYS mode.

(2) Corrected total flow (TOTAL COUNT(C))

The reading corrected for meter error and temperature is integrated and indicated. Other specifications remain the same as (1).

(3) Corrected instant flowrate (FLOW RATE(C))

Instant flowrate corrected for meter error and temperature (hourly) is indicated.

(4) Temperature (TEMPERATURE)

The temperature value currently fed to the instrument is indicated to the first decimal place. If a problem arises in the course of temperature conversion, such as out-of-scale, a default fallback value is indicated.

(5) Blend ratio (BLEND PERCENT)

The blend ratio currently fed to the instrument is indicated to the first decimal place. If a problem arises in the course of ratio conversion, such as out-of-scale, a default fallback value is indicated.

(6) Overall error (OVERALL ERROR)

Correction factor for implementing meter error correction is indicated. [OVERALL ERROR] = E1×E2 where E1 : Meter error correction factor for temperature correction E2 : Flowmeter body's volumetric expansion (3α) related meter error correction factor

8. PREPARATIONAL CHECKS AND OPERATION

8.1 Preparation Before Operation

(1) Ensure that the instrument and related equipment are correctly installed and wired with no place left

unfinished.

WARNING: Make sure to see that the power terminals are connected to a power

source of the rated voltage. Applying a power source of incorrect voltage could ruin your instrument.

(2) Supply power to this instrument and make certain to see that the front panel display is illuminated.

The display will remain unilluminated for one second after power on, which however is by no means any indication of fault.

8.2 Preparational Checks

CAUTION: Allow a warmup period for 60 minutes or so after you turn on the power.

Verify that the instrument does not operate with no fluid flow.

How to Check

(1) Couple sources of simulated temperature and pressure signals. (2) Using the shift keys, select menu items and verify the information displayed.

See the KEY OPERATION MANUAL.

(3) Inject a simulated input pulse train or density signal representing the type of the companion pulse

generator.

(4) Select display menu items of the total mass flow and total calorific flow, and make sure that incoming

pulses are being accumulated. Also, verify that pulse output and analog output are properly generated.

(5) Remove the simulated pulse input and compare the obtained readings on the display with

corresponding theoretical values. Remember that this instrument is not equipped with a counter to accumulate incoming pulses. Hence, an external counter is required.

8.3 Operation

CAUTION: Allow a warmup period for 60 minutes or so after you turn on the power.

(1) Select your power reset or non-reset (accumulated total) option.

See the KEY OPERATION MANUAL.

(2) Turn on power. While the initial check screen remains displayed, indicating that the process of

verifying parameters and variables is in progress after you turned on the power, your instrument will not accept any pulse input.

(3) Place your instrument in service operation by allowing the fluid to be metered.

11. BEHAVIOR IN ERRATIC CONDITIONS

(1) Erratic A/D Converter

If, following energization of A/D converter circuit, the conversion process is not completed within the specified time period, it is found that the circuit has a problem. At this point, temperature and pressure fallback values are used for calculation.

(2) Temperature and Pressure Input Out of Range

If the input exceeds the high limit or falls below the low limit, its default fallback value is used for calculation.

(3) Analog Output Overflow

A full scale output is produced across the analog output terminals.
