GENERAL INFORMATION

SAFETY INSTRUCTIONS

This manual will assist you in operating and maintaining
the GPI electronics supplied with your GPI meter or as an
accessory unit on both local and remote models. The GPI
Electronics can be used in indoor or outdoor applications
where occasional exposure to moisture is common.

• The 4-20 mA Out with Display is available in two ver­sions. One indicates flowrate in units/minute and one
in units/hour. Both indicate flow totals in gallons and
litres.

• The 4-20 mA Out with Display can be used on all GPI
models, including the Precision G series, the Industrial
Grade G2 series, the Commercial Grade A1 series,
and the positive displacement GM series oval gear
meters.

Product differences in this manual are identified by either,
Local or Remote as necessary.

If the meter was purchased with this display, then it will come
calibrated from the factory for gallons “GAL” and litre “LTR”.
Field calibration is also available.

If the unit was purchased as an accessory or remote, the
calibration has not been entered and the end user will need
to configure and calibrate the display.

The GPI 4-20 mA Out with Display is a flow totalizer and rate
meter with industry standard current loop output. The unit is
loop powered, and provides a 4-20 mA analog output propor­tional to the frequency signal for communication with PLCs
and other customer equipment. The 4-20 mA (or 0-20 mA)
output is calibrated under actual flow conditions with simple
push-button calibration. Auxiliary output includes 0-5 VDC.

The microprocessor-based electronics have extremely low
power requirements and are completely powered by the
4-20 loop. The electronics provides the options of local (on
the meter) and/or remote (up to 5,000 feet) display. Flow total
and rate are displayed on a large 6-digit LCD readout with
two-point floating decimal for totals from .01 to 999,999. All
operations are easily accessed with the push buttons on the
display front panel.

CAUTION

This unit is not FM Approved. Therefore, use of this
transmitter with an approved metering system voids
FM Approval.

NOTE: This unit is loop powered, requiring an input power

supply of 8.5 to 35 volts (24 VDC is recommended).

NOTE: Setpoint calibration of the unit is required for the 4-20

mA, 0-20 mA, and 0-5 V output options.

• When measuring flammable liquids, observe precau­tions against fire or explosion.

• When working in hazardous environments, always
exercise appropriate safety precautions.

• When applying external power to the transmitter, use
DC power only.

• Disconnect external power to the transmitter before
detaching or attaching input or output wires.

• Ground loops between sensor and user equipment can
damage the transmitter and can be dangerous.

• If you cannot galvanically isolate the sensor from earth
ground, you may need to use the transmitter’s optically
isolated inputs.

• Be sure O-rings and seals are kept in good repair.

INSTALLATION

CAUTION

Installation should be performed only by qualified
personnel, and in accordance with local governing
regulations.

The following installation guidelines are separated by meter
series and mounting type.

Precision G Series:

• Local – The GX510 4-20 mA Out with Display mounts
directly to the 1 inch MNPT conduit connector.

• Remote – The GX500 4-20 mA Out with Display
connects via an output cable as shown in the Wiring
Diagram.

Industrial Grade G2 Series:

• Local – The GX510 4-20 mA Out with Display requires
the GPI Conduit Connector Kit (Part #113437-01) for
local mounting to the G2 series meter.

• Remote – The GX500 4-20 mA Out with Display
connects via an output cable as shown in the Wiring
Diagram.

Commercial Grade A1 Series:

• Local – The GX510 4-20 mA Out with Display requires
the GPI Conduit Connector Kit (Part #113437-01) for
local mounting to the A1 series meter.

• Remote – The GX500 4-20 mA Out with Display
connects via an output cable as shown in the Wiring
Diagram.

2

GM Oval Gear Series:

• Local – The 4-20 mA Out with Display is mounted
directly to the oval gear meter housing.

• Remote – The GX500 4-20 mA Out with Display con­nects via an output cable as shown in the Wiring Dia­gram.

Mount the GPI 4-20 mA Out with Display using bolts, screws
or standard U-bolts for pipes. Mounting options include:

• Wall

• Pipe

• Meter (1 inch FNPT conduit connection required)

WIRING

This manual refers to various models of GPI flowmeters.
Determine what type of input the electronics will receive and
what type of output, if any, you require. Use the diagrams
found in the wiring diagrams section (if the unit is not already
wired) to correctly wire the system.

The display is externally powered by the loop.

NOTE: Totals will be lost with loss of power on loop.

Environmental

Choose a mounting location suitable for the 4-20 mA Out with
Display. The ideal mounting location is where the:

• flowmeter is as close as possible.

• mounting surface has minimal vibration.

• ambient temperature is +32°F to +140°F (0°C to
+60°C).

• cable lengths are minimal.

Avoid mounting locations where the 4-20 mA Out with Dis­play is:

• subject to constant exposure to water or other liquids
(occasional low-pressure splashing will not harm unit
if cable entry points are well-sealed).

• subject to > 5g shock loading.

• facing the sun directly for long periods of time.

• close to high voltage/current runs, DC motors, internal
combustion engines, or frequency inverters.

Cable Guidelines

4-20 mA Current Loop:

• The current loop itself is very resistant to electrical noise
pickup and shielded cable is seldom needed except in
very “noisy” (electrical) locations and/or when very long
runs (thousands of feet) are used.

Sensor Cabling:

• Some products come with 20 ft. of shielded cable.

• If you require a longer cable, a 100 ft. cable kit is avail­able from GPI, or use Belden 9363 cable. When wiring
longer lengths of cable, be sure to connect the shield
to LOCAL-COM ONLY! (Multiple shield connections
may cause ground-loop problems).

• Some trial and error may be needed because of the wide
variety of user conditions. Try to keep cable lengths
short!

CAUTION

Determine maximum power supply voltage after de­termining maximum allowable voltage of all electronic
devices in the system.

The 4-20 mA Out with Display may come with 20 ft. of cable
to connect to the meter. The customer must supply the com­munication loop cable. Although the unit is usually powered
through the communication loop, there are some circum­stances that might require external power.

Connecting the Equipment:

• Remove the faceplate by removing the four (4) corner
screws.

• Attach wiring from your equipment according to the
following terminal connections and wiring diagrams,
depending on your circumstances.

CONFIGURATION

Configuration determines what information is present on the
LCD display. For instance, total, flowrate, type of calibration,
etc.

The Display has been programmed with many features, which
can be enabled by the end user through the configuration
process. By disabling unnecessary features, day-to-day
flowmeter operation can be greatly simplified, making the
unit easier to use. Alternately, there are several features not
found in the default configuration.

Available features include:

• 0 to 3 totals, either resettable (Batch) or non-resettable
(Cumulative).

• Flowrate or no flowrate. Available in units per minute, hour
or day.

• Three different field calibration methods: K-factor entry,
Dispense/Display or % Correction Factor.

• Various units of measure (some or all): GL (gallon), LT
(litre), IGL (imperial gallon), QT (quart), CF (cubic feet),
CM (cubic meter), BL (42 gal. barrel), CC (cubic centi­meter) or OZ (ounce).

Changing Configuration Settings

Access to the configuration settings require a specific pro­cedure and a pin code available through the GPI Website at
www.gpimeters.net or call GPI Customer Serivce at 888­996-3837.

OPERATION

Computer Display

All operations are reflected in the LCD readout. The large center
digits indicate amounts, where smaller words or “icons” located
above and below indicate specific information regarding totals,
flow, calibration and units of measure.

Computer is on continuously while the loop is powered.

Press the DISPLAY button briefly to switch between the TOTAL
1, TOTAL 2 BATCH and FLOWRATE. Press DISPLAY briefly
to display the TOTAL 2 BATCH. Hold the DISPLAY button for
3 seconds to reset the Batch Total to zero.

When fluid is flowing through the meter, a small propeller
icon is highlighted.

Flowrate Feature

To use this feature, press and release DISPLAY until FLOWRATE
icon appears. The factory set time base will be highlighted to
the right of FLOWRATE (M = minutes, H = hours, D = days).
When FLOWRATE is invoked, the display will be indicating
rate of flow.

Factory and Field Calibration

All calibration information is visible to the user as icons on the
top line of the display, above the numeric digits.

All units are configured with a “factory” calibration. Both
gallons and liters are available (“GL” or “LT” will be displayed).
While holding the CALIBRATE button, briefly press DISPLAY
to toggle between gallons and litres. This factory calibration
(indicated with FAC) is permanently programmed into the
computer and is not user adjustable.

NOTE: Your computer may have other units of measure

programmed into it. If so, holding the CALIBRATE but­ton and momentarily pressing the DISPLAY button will
toggle through all factory set units. Other possible units
are: IGL (imperial gallon), QT (quart), CF (cubic feet), CM
(cubic meter), BL (42 gal. barrel), CC (cubic centimeter)
or OZ (ounce).

Switching between different units will not corrupt the Total’s
contents. For example, in GL mode, the computer totalizes

10.00 gallons, if the user switches to LT mode, the display will
read 37.85 litres (the same volume, different unit).

The “field” calibration may be set by the user, and can be
changed or modified at any time using the calibration procedure
described in the Calibration Section. Totals derived from the
field calibration are invoked when the FAC icon is no longer
visible on the top line of the display.

Batch and Cumulative Totals

The computer maintains two totals. The Cumulative Total
provides continuous measurement and cannot be manually
reset. The Batch Total can be reset to measure flow during a
single use. The Cumulative Total is labeled TOTAL 1, Batch
Total is labeled TOTAL 2 BATCH.

When the Cumulative Total reaches a display reading of 999,999
the computer will highlight an X10 icon. This indicates to the
operator that a zero must be added to the 6 digits shown.
When the next rollover occurs, the computer will highlight an
X100 icon. This indicates to the operator that two zeros must
be added to the 6 digits shown.

CALIBRATION

Field Calibration Procedures
(K-Factor Method)

If the display was purchased as an accessory or remote,
then the field calibration method set at the factory is K-factor
Entry method.

This method allows the user to key in a single point K-factor
value that represents the meter it will be used with. K-factor
values for specific meters can be found on the meter itself,
in Table 1 or www.gpimeters.net.

1. To field calibrate, press and hold both CALIBRATE and
DISPLAY buttons for about 3 seconds until you see
FLdCAL. Release both buttons and you will see Kxxxx.x
(where “x” represents the current field-cal k-factor value).
You are now in the field calibration mode.

9

2. The far left digit will be blinking. The DISPLAY button
can then be pressed to select the digit location and the
CALIBRATE button can be pressed to scroll the desired
value at the blinking position. Edit the K-factor shown to
the desired value. Acceptable K-factor range is 0000.1 to

9999.9.

3. After the new value has been entered, momentarily press
and release both buttons. “CALEND” will be momentarily
displayed. Unit is now ready for use.

4. Notice that the upper display line, the “FAC” icon and all
the units of measure have disappeared.

Alternate units of measure are not selectable when the meter
is operating with field calibration. This calibration is a unique
single-point calibration for the meter and/or application.

NOTE: To return to factory calibration (FAC), press and hold both

CALIBRATE and DISPLAY buttons for about 3 seconds,
until FAcCAL is displayed. Then release buttons. Unit
should return to normal operation and FAC icon is visible.

NOTE: If the field calibration mode is entered and NO fluid is

dispensed, then upon leaving, the computer will use data
from the last successful field calibration.

Field Calibration Procedures
(Correction Factor Method)

If the display was purchased with a meter body then the
field calibration method set at the factory is the Correction
Factor method.

This method allows the user to tweak the factory calibration
by a percent that represents application, fluid or plumbing
differences.

1. To calibrate, press and hold the CALIBRATE and DISPLAY
buttons for about 3 seconds until you see FLdCAL. Release
both buttons and you will see CF-00.0. You are now in the
field calibration mode and values from -99.9% to +99.9%
can be entered.

2. The +/– position appears either as an “underscore” char­acter for plus, or as a “hyphen” character for minus. The
DISPLAY button selects the position and the CALIBRATE
button toggles this character.

3. The DISPLAY button can then be pushed to select the
numeric positions. Press the CALIBRATE button to scroll
from 0 to 9. Enter the percentage of change you want the
display to correct. When satisfied with the value, press
both CALIBRATE and DISPLAY buttons simultaneously.
CALEnd will be displayed and unit will go back to normal
operation, less the FAC (factory calibration) icon.

4. All enabled units-of-measure remain visible and select­able – the entered correction will be applied to all enabled
units.

5. To return to factory calibration (FAC), press and hold both
CALIBRATE and DISPLAY buttons for about 3 seconds
until FAcCAL is displayed. Then release buttons. Unit
should return to normal operation and FAC icon is visible.

The 4-20 mA endpoint settings are independent from the
display calibration. If you reset the response time you MUST
reset the 4-20 mA endpoints.

All units are shipped with the following items preset:

• 4 mA setpoint = 10 Hz

• 20 mA setpoint = 1000 Hz

• Response time = 0.7 seconds

Any new values you set for these items are automatically
saved when the transmitter is powered down, and automati­cally restored the next time power is applied.

Procedure

Before you start, the fluid pumping system should be ready
to make two simple calibrating runs, first at the lowest an­ticipated flowrate, and then the second at the highest antici­pated flowrate. Position yourself so you can easily operate
the transmitter’s pushbuttons. You should be able to see the
indicator light (the small window beside the “4” button).

10

Setting the Low (4 mA) Endpoint:

To set 4 mA at zero flow, go to step 3. Otherwise follow
steps 1, 2 and 3:

1. Start the fluid pumping system. Set it for steady flow at
the lowest anticipated rate (or the rate at which you want
a “minimum” indication).

2. Wait while the fluid flow is uninterrupted for at least 10
seconds.

3. While watching the transmitter’s indicating light, press
and hold both its “SET” and “4” buttons. Release them
when the light blinks.

NOTE: The length of time between “button press” and “light

blink” depends on the transmitter response time. The
maximum is 5.2 seconds. If you can’t see the indicator
light (if you’re outdoors in bright light), you can safely just
count to 10 while holding the pushbuttons.

NOTE: After setting the minimum, the loop current should be

registering at or near 4 mA. Don’t worry if it’s not exact, it
will be correct after setting the high (20 mA) endpoint.

Setting the High (20 mA) Endpoint

1. Start the fluid pumping system. Set it for steady flow at
the highest anticipated rate (or the rate at which you want
a “maximum” indication).

2. Wait while the fluid flow is uninterrupted for at least 10
seconds.

NOTE: If you observe the current loop after completing the

procedure, it should be registering at or very near 20
mA (within the resolution specifications for the present
conditions).

3. While watching the transmitter’s indicating light, press
and hold both its “SET” and “20” buttons. Release them
when the light blinks.

NOTE: During the high and low setpoint procedure, if the new

settings are very different from the previous settings, it is
possible to reverse the 4 mA and 20 mA setpoints so that
the 4 mA frequency is higher than the 20 mA frequency.
The situation corrects itself after you complete both
setpoints. If the new settings are close to the previous
settings, you may safely set either the low and high set­tings independently.

Lockout Feature

This transmitter includes a user selectable lockout feature.
Select the feature after setting the 4 and 20 mA endpoints
during initial use. The lockout feature prevents tampering with
the 4 and 20 mA settings on the transmitter.

Before activating the lockout feature make sure there is no
signal being received by the transmitter. If signal is being
received, deactivate it by one of the following methods:

• Stop the flow through the line that is being recorded.

• Disconnect the output device on the flowmeter.

Locking / Unlocking the Transmitter

Position yourself so you can easily operate the pushbuttons on
the transmitter. You should be able to see the indicator light.

To lock the transmitter, use the pushbuttons to enter the
following sequence with a brief pause between each button
press: 20 – 20 – 20 – SET. The indicator light will blink twice
to indicate the unit is locked.

To unlock the transmitter, use the pushbuttons to enter the
following sequence with a brief pause between each button
press: 4 – 4 – 4 – SET. The indicator light will blink once to
indicate the unit is unlocked.

Checking the Status of the Lockout Feature

To check the status of the transmitter, use the pushbuttons
to enter the following sequence with a brief pause between
each button press: SET – 4 – 20 – SET. The indicator light
will blink once if unlocked or twice if locked.

Optional 0-20 mA Mode

A few current loop systems use 0-20 mA output. The input
signal frequency of “0” produces an output analog signal of
“0” with direct proportionality and no offset.

NOTE: A true loop current of “0” in a loop powered device

like the GPI transmitter is not obtainable. That’s because
the current loop powers the transmitter, and its operat­ing current is non-zero even at zero frequency input. In
0-20 mode, the GPI Transmitter’s loop current will drop
to as near zero as possible at zero input, in most units
between 1 and 2 mA.

Procedure

1. To enter 0-20 mode, simply press and hold all three push­buttons simultaneously (4, SET, and 20) at any flowrate.
Continue holding until the indicator light blinks (light will
blink in up to 5 seconds) and release all buttons. This
sets the LOW END calibration point to zero/zero.

2. Set the 20 mA endpoint as described above under 4-20
mA calibration.

3. The special 0-20 mode will remain in effect until a new

4 mA endpoint is established in the usual way.

Auxiliary 0-5 VDC

The 4-20 mA Out with Display is equipped with an auxiliary
voltage output with a range of 0-5 VDC. This signal is capable
of dropping to within a few milliVolts of zero, and thus may
be more suitable for use in the 0-20 mode.

No special equipment is required to use the 0-5V output,
but wiring to customer equipment is different (see Wiring
Diagram 4).

11

Changing Response Time

The 4-20 mA with Display comes from the factory with a
default 0.7 seconds response time.

WARNING

If you reset the response time (procedure detailed be­low) you MUST then reset the 4-20 mA endpoints.

To give good performance with a variety of sensor types,
many frequency-to-analog converters, including the GPI
4-20 mA Out with Display, offer two or more settings for
“response time” (sometimes referred to as “settling time” or
“averaging time”).

• Longer (slower) response times are needed for sensor
types that generate very low frequency outputs (like
GM Series oval gear flowmeters).

• Operating a meter at high flowrates may require a
shorter (faster) response time to achieve the best
transmitter performance.

• Shorter (faster) response times are preferable for sen­sors that generate higher frequency outputs (GPI turbine
meters, for example).

• Longer (slower) response times are also appropriate in
situations where sensor-output frequency fluctuates or
wobbles substantially.

The GPI 4-20 mA Out with Display offers a choice of five re­sponse-time settings, selectable by the unit’s pushbuttons.

MAINTENANCE

Check cable-entry seals periodically. Tighten and/or apply
sealant if needed. This is especially important in environ­ments containing heavy concentrations of dust, oil mist, or
other residue.

Check all wiring connections occasionally for oxidation or
corrosion. Clean and re-seat if such conditions are noted.

If necessary, check and re-seat any connections that may
have been subjected to strain (during rework or construction,
for example).

Procedure

1. Start with the unit unpowered. If the unit is presently

operating, temporarily disable its external power supply.
Be sure to allow at least 30 seconds to elapse with unit
unpowered.

2. Press and hold the “4” button. While holding, watch

the indicator light and power up the 4-20 mA Out with
Display.

3. Shortly after power is applied, the light will blink one or

more times. Count the number of blinks (from 1 to 5 blinks)
and release the button after the blinking has finished.

NOTE: If necessary, repeat steps 1 through 3 to get the

number of blinks corresponding to the response time
you want.

Blinks Response Time

1 blink 0.3 second
2 blinks 0.7 second
3 blinks 1.3 second
4 blinks 2.6 second
5 blinks 5.2 second

In normal operation, the 4-20 mA Out with Display always av­erages two sequential input readings. The time delay from an
abrupt change in input frequency to a final, stabilized output
reading is always twice that shown in the above table.
