Section 1

OVERVIEW OF THE ULTRA 3000

HARDWARE AND SOFTWARE

The Daniel Ultra 3000 Electronic Flow Meter (EFM) consists of a series of hardware and

software configurations that meet the flow measurement requirements for a wide range of

applications. The hardware requirements will vary, depending on the application, but generally

the Ultra 3000 may be used with any Personal Computer (PC) that uses Microsoft’s Disk

Operating System (MS-DOS). The versatile nature of this product allows you to implement the

Ultra 3000 system in a variety of settings and to network the various devices required by the

system.

The Ultra 3000 hardware is designed for outdoor use. The hardware’s lightweight and versatile

mounting scheme facilitates one-man operation for simple installation, configuration, calibration,

data collection, and maintenance. The Ultra 3000 Central Processing Unit includes two 9600

Baud serial communication ports, one LPT1 (printer) parallel port, 1 MB Programmable Read-

Only Memory (PROM - expandable to 2 MB), 0.5 MB Random Access Memory (RAM -

expandable to 8.5 MB), and an internal clock.

The software of the Ultra 3000 is based on the Electronic Flow Meter Operating System

(EFMOS). EFMOS provides a consistent user and programmer environment across Ultra 3000

hardware models and successive generations of Ultra 3000s. EFMOS has been designed as a

standard, not only for future Daniel Electronic Flow Meter products, but also for the industry.

The central goal of EFMOS is to integrate those functions that are essential to any EFM

application. EFMOS implements these functions in a consistent, universally accepted manner,

while allowing user configurability to maintain flexibility in most aspects of the operating system

and the applications derived for the Ultra 3000.

EFM-Access (EFMACCS) is the PC-based software program provided with the Ultra 3000. All

groups of users, including Field Technicians and Flow Engineers, can use EFM Access for many

operations. EFMACCS is interactive and menu-driven for ease of use and minimal training.

The Ultra 3000 becomes operational when instructions are fed to it through a PC. This PC is

usually a laptop computer because of the ease with which a laptop can be carried.

An EFM Access program disk is loaded directly into the laptop. This disk, which is supplied by

Daniel Industries, prepares the laptop for accepting information and creating programs related to

the Ultra 3000 operation. Start-up consists of Definition download and initial Configuration.

SECTION 1 1-1

________________________________ Ultra 3000 Field Technician’s Manual

SEP 1997

Various types of data can be collected from the Ultra 3000 and then viewed or printed from the

laptop. These include:

- Current Definition and configuration for "cloning" other systems

- Field data logs for diagnosing any problems with the site

- Audit trail and audit data logs for accounting

Most field maintenance of the electronics consists of enhancing the site by adding additional

hardware or isolating a nonfunctional card and replacing it.

SYSTEM DESIGN

The primary information needed to prepare the Ultra 3000 for operation comes from the

Definition and Configuration portions of the EFM Access program.

Definition

The Definition program, supplied either by Daniel Industries or a Flow Engineer with the

user’s company, defines the specific application to be used. This includes the number of

meter runs, number of tubes, type of metering elements, calculation methods, and so on.

Configuration

The Configuration program allows the Field Technician to set many different parameters.

These include communications parameters, calibration inputs, pipe/orifice sizes, data

collection, configuration changes, and so on. These parameters can be changed by following

a series of prompts incorporated into each program. The Ultra 3000 can also be configured

by remote telecommunications.

Tool generation programs

When necessary, a software engineer will be asked to create a new tool or protocol driver.

The entire system, through the Definition level, is "open." Run-time licenses, documentation, and

support are available, for reasonable fees, to assist third parties, OEMs, or customers, in

developing their own Definitions, configurations, or tools and protocol drivers based on EFMOS.

LIQUID CRYSTAL DISPLAY (LCD) PANEL

The display panel is set to turn off its display if no buttons are pushed for a user-defined number

of consecutive seconds (usually 60). The LCD may be configured to go blank and save power

or to stay on and scroll through all available screens when the user-defined amount of time

elapses. Although the LCD cannot be damaged by operation in temperatures as low as -30°C,

the display stops updating at approximately -10°C.

DISPLAY BUTTON

The Display Button is identical in function to the Up arrow button and may not be present on

some display panels.

UP AND DOWN ARROW KEYS

The UP and DOWN scrolling arrow keys are designed to take you screen by screen through the

display panel of the Ultra 3000. To use these keys, press and release to advance one screen. If

you press and hold these buttons for longer than one second at a time the contrast of the LCD

panel will begin to change until you release the button. If the user-defined time period has

elapsed, pressing one of these buttons will bring the panel back.

DISPLAY SCREENS

Data Points Screens

Pressing the Down button will cause the first Data Point Screen to appear. This screen contains

data for four data points. Two lines are allocated to each point. The first line contains the data

point’s name, the second line contains the data point’s Engineering Units and most recently

downloaded value. If the user advances to an incomplete display screen, the remaining lines will

be filled in as their data becomes available. If the user advances to an empty display screen, press

the Up button to return to the previous screen, or press the Down button until it "wraps around"

to the first page again.

Each page can be viewed individually by pressing the Up and Down buttons. Each time a button

is pressed, a timer is reset which will cause the display to erase after it expires. Typically the

timer value is set to 60 seconds. Its value can be modified using the EFM Access program. A

scroll feature is available which will cause the display to automatically scroll through the display

pages at specified time intervals when the user-defined time period has elapsed. The duration

of the time interval can be set using the EFM Access program.

System Screens

The System Screens consist of diagnostic information. The diagnostic screens follow immediately

after the last Data Point page. These screens are scrolled and viewed as explained previously in

DATA POINTS SCREENS. The diagnostic screens defined below, in general, are designed to

assist the software engineer in system troubleshooting. They are described using specific technical

terminology and, therefore, may not be of interest to the Field Technician.

Diagnostic Counters

cksm 0 akto 0

upls 0 nak 0

clcs 0 ack 0

rxto 0 0

avgs 0 0

Cksm A counter of checksum failures reported by the display unit.

Upls This counter is incremented each time a set of sample data is uploaded and

processed by the 186.

Clcs A counter of calculation ladder overrun errors. This counter will increment if the

calculation ladder’s processing time exceeds the time of the data gathering

interval.

Rxto Counter of FIFO receive timeouts. This counter is incremented if a period of 1.7

seconds elapses during which the 186 receives no communication from the Traffic

Cop.

Ack This counter is incremented each time a line is output to the display unit, when

the display unit passes its acknowledgement back to the 186 via the Traffic Cop.

Nak This is a counter of NAK’s received by the 186 in response to downloaded text

packets. Each time the traffic Cop processor fails to find the display unit’s

acknowledgement within a specified interval, it sends the 186 a NAK instead of

an ACK. Normally, the NAK occurs when the display unit is using the interface

to communicate with the display hardware.

AckTO Each time the 186 outputs a line and fails to receive either an ACK or a NAK

within four seconds, it increments this ACK time-out counter.

Time_Now A counter of the number of seconds elapsed since 1/1/70.

RdSth A count of the number of READ_STATHAM commands sent to the Traffic Cop

by the 186 ( normally zero ).

WarmS A counter of the total number of warm starts which have occurred since the last

cold start.

FrmEr This counter is driven by the 186 software. It is incremented each time a new

message is found in the FIFO imbedded in the midst of the preceding message.

It indicates that a byte has gotten lost in a FIFO input message.

FifEr A count of invalid messages received from the Traffic Cop.

BlkEr This counter is driven by the 186 software. It is incremented each time an

uploaded data block is received without being preceded by a

"start-of-block-upload" message. This counter indicates some sort of FIFO

mistake.

DspU This counter is driven by a failure flag which is uploaded by the Traffic Cop with

each one-second data sample. The flag indicates that the display unit failed to

respond when the Traffic Cop tried to access it. This occurs under normal

operation when the Display Unit uses its I2C interface to communicate with the

display driver chips.

StUpl A count of the number of Statham uploads initiated by the Traffic Cop. This

counter increments by 2 for each initiated upload.

Math A count of math errors detected by the floating point math package.

BadTm A count of the number of invalid date/times received from the Traffic Cop. If this

counter increments, it indicates that the TC’s hardware clock is performing

erratically.
