Introduction

The Model 505 Rate/Totalizer is designed to acceptfrequency or pulse inputs from a wide range offlowmeters and to display flowrate, a re-settable totaland an accumulated total directly in engineering units.The instrument is compatible with a wide range offlowmeters and a DIP switch on the input board en-ables the circuit to be configured for millivolt signals,reed switches, pulse trains and most other signal types.

Three different versions of the instrument are avail-able:

Battery Powered Version

Loop Powered Version

DC Powered Version with high and low flow alarms

The Model 505 is fully programmable with K-Factors,decimal point positions, filter constants and timebasebeing programmed via the front panel switches.

The instrument is housed in an attractive polycarbon-ate enclosure which is completely watertight and whichenables it to be mounted directly on a flowmeter orwall mounted using a special universal bracket.

Intrinsic Safety Considerations

At the date this manual was issued, two versions of theModel 505 were certified for use in hazardous areas toboth CENELEC and Australian Standards.

The versions which have certification are:

Model 505i.20

Model 505i.40

Model 505i.21

Model 505i.41

CENELEC Approval: Kema

SAA Approval: Ex 2003x

Type of Protection: Ex ia

Group: IIB

Temperature Class: T4 at ambient temp. or 60C

When installing in hazardous areas, the instrumentmust be installed according to the guidelines given inthe Intrinsic Safety Connections Section and in accor-dance with standards for wiring and installation in haz-ardous areas.

CSA/FM approval has been applied for and will beoffered as the standard configuration when available.

Programming Overview

The Model 505 is fully programmable with all param-eters being stored in memory.

The Program Mode can be entered in one of two ways:

1. By removing the lower cover strip (i.e. the darkgrey strip along the bottom of the enclosure) andreplacing it after rotating 180. This brings a smallmagnet on the inside of the cover strip in contactwith a reed switch inside the instrument. The pro-gram key is then pressed to enter the ProgramMode.

2. By removing the front section of the enclosurewhich contains the main processor board and bat-teries. Once removed, the PROGRAM key ispressed to enter the Program Mode.

The PROGRAM switch is used to step through theprogram (CAL sequences) and the and keys onthe front panel are used to change and increment theflashing digits.

Up to nineteen CAL steps are accessible, dependingon which options are installed. The CAL number isdisplayed on the lower display and the parameter isdisplayed on the upper display.

Program Steps

Step Comment

CAL 1 Scaling Factor - Whole numbers (K-Factor)

The Scaling Factor is the pulses per unit ofmeasure (i.e. pulses/gallon, pulses/barrel etc.).The Scaling Factor can be programmed in therange of 0.2 to 29,999.

CAL 2 Scaling Factor - Digits to the right of the deci-mal point.

CAL 3 Frequency Divider

This calibrates the Model 505 to a specific

frequency range where:1 = .25 to 500 Hz

2 = .25 to 5KHz

CAL 4 Decimal Point Placement for Rate Display

The flowrate can be displayed with 0, 1, 2, or 3decimal places. Enter number of places.

CAL 5 Timebase for Rate

The Rate can be displayed in units per sec-ond, minute, hour, or day. Enter:

0 = second

1 = minute

2 = hour

3 = day

CAL 6 Filter

Fluctuations in the flowrate can be filtered outso that the Rate and 4-20mA transmission (ifused) are held steady. The filter value is pro-grammed between 1-99 where 1 representsno filtering and 99 is maximum.

CAL 7 Decimal Point for Total Display

The totals can be displayed with 0, 1, or 2decimal places.

CAL 8 Total Conversion Factor - Whole Numbers

CAL 9 Total Conversion Factor - Digits to the rightof the decimal point.

The Total Conversion Factor enables the rateto be displayed in one engineering unit andthe totals to be displayed in another engineer-ing unit.

Set to 1.000 if totals and rate are in the sameengineering unit.

CAL 11 Low Alarm - Digits to the right of the deci-mal point.

CAL 10 to CAL 13 are displayed regardless ofwhether the high and low alarms are installed.If the high and low alarms are not installed,these parameters can be ignored.

CAL 12 High Alarm - Whole numbersCAL 13 High Alarm - Digits to the right of the deci-

mal point.

CAL 12 and 13 program the flowrate abovewhich the high alarm relay will close. Thevalue can be programmed in the range 0 to49,999.9999.

CAL 16 and 17 represent the flow rate at whichthe output will reach 20mA.

CAL 18 Identification Number

Not currently used.

CAL 19 Communication Parameter

Not currently used.

Calculation of Rate and Total

The flowrate, R, is calculated as follows:

R =

where: f is the input frequency in Hz.

H is the timebase of rate and is 1 for seconds,60 for minutes, 3600 for hours and 86,400for days.

S is the Scaling Factor.

The Scaling Factor, S, is equal to the K-Factor of theflowmeter expressed in pulses per unit volume.

The user programs the Scaling Factor and selects thetimebase during the Programming procedure.

Total Conversion

The Total Conversion feature enables the rate to bedisplayed in one engineering unit (i.e. gallons/minute)and the totals to be displayed in another engineeringunit (i.e. barrels).

fx H

S

The Scaling Factor is always programmed in the unitrelating to Rate, and the Total Conversion constant isa division factor which can be used to convert thetotals to the different unit. The Total Conversion fac-tor affects the resettable and accumulated totals andis limited between 0.01 and 2000.

For example:

If the Rate is required in gallons per minute:

1. The Scaling Factor would be programmed as

pulses per gallon.2. The timebase would be programmed as minutes.

If the Totals are required in barrels:

3. The Total Conversion Factor is programmed as42 (there are 42 gallons in a barrel). All totals willnow totalize in barrels.

Some common units are given below together with theTotal Conversion constant which should be pro-grammed.

Rate* Totals TOTCON

Gallons (US)/ Barrels (oil) 42.000

Liters/ Kiloliters 1000ml/ Liters 1000

Mgallons/ Acre-feet 0.32587

* Units per second, minute, hour or day. The timebaseis programmed separately during Programming.

Filtering (Dampening)

Frequency fluctuations caused by pulsating flow througha flowmeter, often makes the Rate impossible to readwith any precision.

The Flow Computer has a digital filter which will aver-

age out these fluctuations and enable the Rate to beread to four digit accuracy. The ability to select asuitable filtering level means that highly accurate andstable readings can be obtained without excessivelag. When the Rate is retransmitted via the 4-20mAoutput, the filtering will also average out any fluctua-tions on the output.

The diagram below shows a pulsating signal input to-gether with the effect of filtering.

Simplified Setup for Model 505

1. Insert screwdriver blade under end of dark graystrip at bottom of 505 and pry up. Remove stripand swap is end for end. Reinstall.

2. Press Program key. Unit will go into calibration mode.

3. See Chart below.

4. Remove gray strip at bottom of 505. Swap it endfor end. Reinstall. Unit will go into OperationalMode. Unit is ready.


The battery powered version of the Model 505 is de-

signed for operation in the field without external powersources. Lithium batteries provide sufficient power tooperate the instruments for up to 3 years and the op-erator is warned of a low power condition by a mes-sage on the LCD display.

New batteries can be purchased through INVALCO orour distributors and replaced in the field. There aretwo battery packs in each instrument and care must betaken to replace only one pack at a time so that thereis always power connected to the memory.

4-20mA Output Version

The 4-20mA output provides a two wire retransmissionof the flowrate. Both the 4mA and 20mA points arefully programmable so that the output can span acrossthe entire operating range or, alternatively, across asmall section of the operating range.

The response rate of the output is very fast, makingthe instrument suitable as a frequency to current con-verter in closed loop systems where a fast response isnormally required.

The instrument draws its operating power from the 4-20mA loop and uses a Lithium Battery for memorybackup.

Since the 4-20mA output is designed to provide powerto the Model 505, it is not isolated from the input.Hence, all sensors must be self powering (such asreed switches and coils). If external power is requiredto power the sensor (i.e. Namur switches, Hall Effectsensors or opto-sensors), the power supply deliveringthe external power must be isolated from the 4-20mA

loop supply.

DC Power Version

The DC Power version will operate from an externalpower source between 12-28 VDC and draws no morethan 8mA.

The instrument uses a Lithium battery for memorybackup capable of maintaining memory for long peri-ods.

Open collector outputs are also provided for high and

low flowrate alarms. They can sink up to 200mA andcan be used to power external relays, lights or audiblealarms. The outputs are internally protected againstvoltage spikes caused by relays and coils.

Both outputs are separately isolated via opto isolators.

The switching points can be programmed during thesetup mode and the low flow alarm will switch on when-ever the flowrate drops below the programmed flowrate.Similarly, the high alarm switches on whenever theflow exceeds the high setpoint.

Typical Connections

Flowmeter Input

The Model 505 has an input conditioning circuit whichwill accept signals from most pulse or frequency pro-ducing flowmeters. A six position DIL switch on therear panel enables the input circuit to be configured fordifferent signal types.

The input will interface directly to:

Turbine Flowmeters

Open Collector OutputsReed Switches

Logic Signals

Two Wire Proximity Switches

For pulse or logic type signals, the input switchingthreshold is 1.3 volts. Accordingly, the input signalmust have a low voltage of less than 1.2 volts and ahigh voltage of greater than 1.4 volts.

Separate input terminals are provided for the coil inputso that high inductance values can be handled, whilemaintaining the intrinsic safety of the system. For acoil, the minimum input voltage is 20mV P-P.

All inputs are protected for over voltage up to 25 volts.The following are examples of interconnection to vari-ous signal outputs, and a circuit diagram of the input isalso provided.

Installation

Wall Mounting

A wall mounting bracket is supplied with each instru-ment. The bracket should be attached to the wall usinground head screws (do not use counter sunk screws).The bracket is mounted with the tray section at thebottom. The instrument is then attached to the bracket atthe bottom with two screws (see diagram below).

Removing the Front Panel

The front of the instrument is removed as follows:

1. Remove both the top and bottom cover strips (i.e.the dark plastic strips on the front) by levering ascrewdriver under one end.

2. Undo the seven screws retaining the front. Notethat the screws should not be removed from thefront panel as they are retained by O-rings.

3. Pull the front panel free from the housing.

Replacing the front panel of the instrument is the reverseprocedure. However, ensure that the front panel is alignedat both connector points before tightening the screws.

The Main Electronics

The front section of the housing contains the micro-processor, batteries and display.

When replacing the Lithium battery packs, only onebattery pack should be replaced at a time so that thereis always one pack connected to power the memory.

NiCad batteries should not require replacement, butthey may need to be charged for a short period beforethey will provide effective backup to the memory.

It is also possible to adjust the display contrast via asmall potentiometer on the board. The DISPLAY CON-TRAST control is shown below and this can be ad-

justed for optimum contrast.

Adjacent to this control is a RESET switch which canbe used to reset the microprocessor. Note that press-ing this button will reset all Setup Parameters and setall totals to zero.

Intrinsic Safety Connections

When installing the Model 505i in hazardous areas,the wiring and installation must comply with appropri-ate installation standards.

The approval uses entity parameters on the input forconnections to the flowmeter, and an associated ap-paratus type approval for the 4-20mA output. The 4-20mA output must, therefore, only be connected as

shown on the following page, to barriers with the speci-fied parameters.

The Model 505i will connect directly to a turbineflowmeters or paddlewheel with a certified I S coil orother certified I S sensors which produce a pulse out-put, provided they do not exceed the following inputparameters:

Ui = 24V

Ii = 20mA

Pi = 320mW

The maximum allowed capacitance and inductance ofthe pulser or coil, including cabling is:

Cext = 60uF

Lext = 1.5H

The internal capacitance and inductance of the Model505 seen on the input are negligibly small and themaximum voltage and current produced by the Model505 on its inputs (terminals 1 to 4) are:

Uo = 10.0 volts (open circuit)

Io = 9.0mA (short circuit)Devices such as reed switches, which can be classedas Simple Apparatus as defined in the CENELECstandard EN50020, can be connected to the Model505 without certification.
