1.INTRODUCTION TO THE LINEAR MULTI-FLOW COMPUTER

4050

Designed to meet the ever-changing requirements of flow metering, the Multi-flow computer can be tailored to
virtually any flow applicati on. It is desi gned to accept up to 3 meters and correct for temperatur e changes and
produce a usable output in whatever flow units you require. The 4050 is designed to work with manifold
systems and switches relays that are adjustable at which point they trigger. This output (dry) can be used to
change valve states and switch which meter measures the flow.
Each 4050 is programmed to your own individual requirements, software is written for each unit as and when
required. Each 4050 comes standard with a frequency input card, an analogue input card , a relay card and a
communication card. Other cards are optional, please call for additional options.

(COX) MODEL

Frequency Input Card

32 point Linearization curve for the derivation of flow and a programmable factor for unit conversion.
Programmable cut-off points enable displays of both frequency and flow to be inhibited below pre-set values.
The update is programmable from 0.02 seconds up to virtual infinity. (Standard)

Up to three freq uenc y inp uts ca n be ac ce pted fr om fl ow sen so rs; eac h inpu t wit h a

Analogue Input Card 16 bit Resolution Up to six analogue process inputs 0-10V or 4 to 20mA, are

available for use with sensors of temperat ure; flow; dens ity; vis cosity; pressures - absolute, bar ometric, ga uge
or differenti al, and other fact ors requiring compens ation. Each input has a five point Linearization curve. For
conversion to alternative mass units a programmable mass factor can be used.

Analogue Output Card 16 bit Resolution Up to three analogue outputs 0-10V or 4 to 20mA,

proportional to any desired parameter, are available for connection to remote facilities such as alarms,
indicators, chart recorders, PLCs and the like. The analogue output reference parameter may be configured by
the user.

Pulse Outputs Three TTL o r op en c olle ct or o utpu ts are av ai labl e fo r ret rans mi ss ion of rat e, or f or out put of

pulses per unit volume of total. These outputs, too, may be connected to remote indicators, totalizers or PLCs.

Relay Card

purposes. If the process includes a batching unit or controller, the relays can be used to control valves
solenoids or pump starters

The Multi-flow can accommodate up to three volt-free relays which can be deployed for alarm

Communications To monitor paramet ers or pro gram c al ibrat ion dat a RS23 2, RS 485 and in terf ac es c an be

incorporated. For connection to panel or desk mounted printers either a serial or parallel port can be
incorporated, with the option of time and date indication.

The Main Display The standard display is alphanumeric with red dot matrix characters, 152mm wide and

18mm high, which give an exceptionally wide viewing angle. The display itself comprises three fields: on the
left, a maximum of five characters may be used to give the parameter i dentity; i n the centre is the read-out of
the quantity being measured; and to the right are the characters defining the units of measurement. These can
be changed by the end user. User test routines, and buzzer.

Data Entry All calibration data are entered by means of a hand-held infra-red keypad following a successful

pass-code entry.
To prevent incorrect data entry, when two Multiflow units are positioned in close proximity, the reception of the

unit that is not being addressed can be inhibited by a sequence of keystrokes on the front panel keyboard of
that unit.

Frequency

(gallons, litres; etc) by interpolation between points and, by extrapolation, from the first and last two points of
the curve. An engineering factor is included for the conversion of units.

Frequency range:
The default range is 0.5hertz to 65kHz with accuracy +/- 0.002Hz +/- least significant digit. A low cut off can be
programmed by the end user, which will allow the computer to measure frequency down to 0.01 of a Hz.

Signal conditioning:

By Special request the COX 4050 can take signals from contact closure (reed switch): sine wave; low level
input to base of PNP transistor and two wire modulated curren t frequency inputs. The default is a st andard TTL
type signal input or voltage pulse.

Sensor Excitation Voltage

An adjustable 1.5 to 24-volt dc output. Default is 12volts. Can be adjusted by the end user, it does involve
adjusting a pot entiometer.

CAUTION

Users are advised that although the equipment has protection and conforms to CE approvals, for trouble free
operation the Multiflow system should be connected to a clean power supply; i.e. free of noise and not in the same
phase as heavy machinery.

Any machinery using heavy contacts in the immediate proximity of Multiflow should be suitably suppressed.
Inductive loads switched by the volt-free relay contacts should be fitted with suitable snubber networks.

3. PROGRAMMING THE COX 4050

Entering The Programming Mode

Press the right arrow key until Secondary is displayed. Press the alter key and.’CODE ****’ will be displayed. A
four-digit code can now be entered (serial number). On each press of a key the
sequence from left to right. When all four
shows ‘WRONG CODE’ then try again making sure that you are entering the correct code, as each instrument
has a different code setting. If a mistake is made during setting, then use the CLEAR key and try again.

If you are sure that the code is correct and the instrument still shows WRONG CODE then it is probable that
the batteries need changing in the hand held remote control.

If you press t he A LTE R key b y mi stak e th e dis play wil l reve rt to normal after approx. 20 seco nds. Pres sing the
Å Æ keys will have the same effect. Pressing any other key will reset the timer allowing sufficient time to enter
each digit of code.
Exit program mode by pressing clear.

The Code Number

The code number for each instrument is taken from the last 4 digits of the serial number. The serial number can
be found on the front page of this manual, on the rear of the instrument, and is also displayed when the
instrument is first powered up, and finally by entering the Front panel Test routine.

For complete security it is recommended that the remote controller should be kept in a safe and secure place.

Unable To Enter A Code?

1) Enabling and disabling the Infrared hand held keypad.

The infra-red keypad will work with any COX unit and therefore it may be necessary to disable this function on
one unit where they are in close proximity. To LOCK OUT the infrared keyboard you must enter the Front Panel
Test Routine and select N for the ENABLE IR control. Once locked out, the infrared keypad is totally inactive on
that particular unit and the lock LED will be lit in the lower square panel. With the REMOTE OFF the displays
may still be viewed by means of the front panel keys. To restore operation of the infra-red keyboard use the
Front Panel Test Routine and select Y to the ENABLE IR menu.

2) Automatic LOCK OUT

In some cases the instrument itself will inhibit the ALTER key as it may be performing a sequence of events
that can not be interrupted, i.e. BATCHING. Please see the special instructions if applicable.

Unable To Use The Keys Or Key Bounce

If you are exper ienc ing key bounce or you are un abl e to us e the keys then there is probably interference with
the infra-red remote control. Problems may occur when trying to operate the unit in
sodium lights etc. If there are problems then please contact your supplier.

3) Use the ÇÈ keys to select the required character for that position and the ÅÆ keys to alter the po sition of
the cursor. Using these key, the unit s on the right hand side may be altered.

4) To move the cursor to the left hand side of the display press the
across.

5) Use the ÇÈ keys to select the required character for that position and the ÅÆ keys to alter the position of
the cursor. Using these keys the display designation may be altered.

6) Once the de sired character s have been programmed then pressing t he
display.

7) Use the ÇÈ keys to select another display to be altered and repeat the above sta ges.

IMPORTANT NOTE:
that the display designation is limited to four or fewer charact ers, otherw ise the displ ays will overlap
causing apparent corruption. If this should occur then the number of characters for the display
designation should be reduced, after which the display will return to normal.

In some cases the unit may prevent changes to the display. This is because the instrument needs to
have these displays fixed to run correctly. See any special instructions supplied.

(Under Secondary)

Setting RTC

Setting the real time clock. When either the time or the date is viewed pressing ALTER will enable the user to
set the time/date.

Manifold ON/OFF

When this display is showing, pressing ALTER on the IR keyboard will toggle this selection, ON or OFF. When
off a manual option is enabled. This option allows the user to set the machine up for multiple meters and a relay
state change at a particular set points.

Manifold Autoranging Trip Points (Section 12)

Used for switching valves etc. These values are set for at what point relays open or close (usually used to
control valves).
Under the menu system the display will show SETUP AUTO pressing alter will display the following. Access by
using the ↑↓.

1
2
3
2
These values should not be set above or below the next meters calibration figures, leave some space for the
meter to switch over. An example is if meter 1 is set & calibrated for 20(1gpm) to 1100 hz(100gpm) and meter 2
at 100(85gpm) to 1000hz(500gpm) set trip point 1 to 2 at about 1000hz(saying 1000Hz= 92gpm) and set 2 to
1trip point at about 110 hz (sayi ng 110Hz = 90gpm) .This allows room for som e varian ce and avoids 4050 being
in a switching loop.
The user should take care to enter a reasonable hysterisis. Refer to section 12 for the relay truth table.

Channel “ # ”

This display shows the current channel number running, however if the MANIFOLD OFF option is running then
pressing the ALTER key will change the channel number, (relay and analogue output)

VOL ON / MASS ON
Pressing ALTER (IR Keyboard) will select the VOLume or The MASS to be running. The effect is:

↑

2 0.0 Hz This shows the trip point in Hertz from meter 1 (Chan 1 low flow) to 2

↑

3 0.0 Hz This shows the trip point in Hertz from meter 2 (Chan 2. medium flow) to 3

↓

2 0.0 Hz This shows the trip point in Hertz from meter 3 (Chan 3. high flow) to 2

↓

1 0.0 Hz This shows the trip point in Hertz from meter 2 (Chan 2. medium flow) to 1

1. Each time t he AUTO MANIFOLD changes the display will change to the new channel and display
either the VOLume or the MASS flow rate.

2. If fitted the analogue output will represent Volume or Mass flow rate.
