IV. INSTALLATION of transmitters is normally done at the factory when
the meter is assembled, but may be made in the eld with the meter
stopped (i.e. no ow). Depending upon what situation exists, various
steps for installation apply and the procedures are outlined below.
1. REMOVE the existing totalizer or indicator or transmitter by
removing all the mounting screws and lifting the unit o the meter
head.
2. CLEAN METER HEAD of all dirt, glue, gaskets and other foreign
material.
3. TOTALIZER DRIVE MAGNET must be removed from the vertical
shaft tip of meters equipped with a totalizer so that the transmitter
drive clevis (#35) can be installed on the vertical shaft tip. The totalizer drive magnet can be removed by loosening the set screw in the
side of the magnet hub and sliding the assembly o the vertical shaft.
4. INDICATOR DRIVE GEAR must be removed from the vertical
shaft tip of meters equipped with indicator-totalizers so that the
transmitter drive clevis (#35) can be installed on the vertical shaft tip.
The indicator drive gear can be removed by loosening the set screw
in the side of the gear hub and sliding the assembly o the vertical
shaft.
5. TRANSMITTER DRIVE GEAR must be removed from the vertical
shaft of meters equipped with an old style McCrometer Model TR01
or TR06. The transmitter drive gear can be removed by loosening the
set screw in the side of the gear hub and sliding the assembly o the
vertical shaft.
6. VERTICAL SHAFT assembly must be removed from the meters
equipped with an old style McCrometer CN06 indicator, TR01 or TR06
transmitter (.100” dia. vertical shaft tip) and replaced with a vertical
shaft that has a 3/16” diameter tip. Vertical shaft removal can be accomplished by removing the two vertical shaft collar bearing mounting screws in the meter head and pulling the vertical shaft directly out
of the top of the meter. Remove the vertical shaft collar and bearing
assembly from the vertical shaft by loosening the set screw in the side
of the collar and sliding the assembly o the vertical shaft.
7. REPLACEMENT VERTICAL SHAFT for meters with
old style McCrometer models CN06 indicators, TR01 or TR06
transmitters, should be inspected to be sure it is not bent
or damaged. Install the vertical shaft collar and bearing
assembly on the new (3/16” diameter tip) vertical shaft,
30119-33 Rev. 1.8/04-14
5
but do not tighten the collar bearing set screw yet. Insert the vertical
shaft assembly, plastic tip rst, into the meter head and rotate the
shaft gently until it is engaged in the driven miter gear shaft of the
miter gear frame assembly. Set the collar and bearing assembly into
the hole in the meter head and replace and secure the two screws
that hold the collar bearing in place. Do not over tighten the screws
or the bearing can cock and cause drag. Turn the vertical shaft to
check for bind or drag. Note: If the meter is in a pipeline full of
water, then a slight drag will be created by the propeller moving
through the water. Should any bind or drag be apparent it can usually be corrected by adjusting the vertical shaft assembly. Slide the
vertical shaft down until it rests against the driven miter gear shaft,
then lift the vertical shaft up about 1/64 inch. Tighten the set screw
in the side of the collar bearing assembly.
8. ADAPTER PLATE part number A-2-4108, and gasket part
number 1558-3, must be attached to the top of the meter head on
the old style McCrometer LP21 (3 hole bolt circle) and all ML45, 47
and 49 meters. The adapter plate can be secured to the meter head
by three mounting screws (part number 1116-8-12) after the gasket
has been centered on the head. Throughout the rest of the instruction
manual, the top of the adapter ring will be referred to as the top of
the meter head.
9. TRANSMITTER DRIVE CLEVIS (#35) must now be installed on
the meter vertical shaft. Place the drive clevis (#35) on the vertical
shaft with the forked end up. Position the drive clevis so that the
top of the clevis is 1/8” below the top surface of the meter head (on
non-reversing models the entire ratchet assembly should be placed
on the vertical shaft and the measurement taken from the top of the
forked portion). Place the plastic drive clevis coupling (#36) on top
of the drive clevis (#35) with the forked portion of the drive clevis
fully engaged in the slot in the clevis coupling (#36) and the larger
diameter hole in the coupling (#36) facing up.
10. TRANSMITTER BASE O-RING (#38) should be covered with
a thin coat of silicone grease and placed in the o-ring groove in the
bottom of the transmitter base (#11).
11. POSITION OF TRANSMITTER on top of the meter head can be
made in one of four directions for the easiest possible reading. Normally the units are attached so that they can be read when looking
upstream. Be sure the drive clevis (#35) is in proper alignment and
makes a positive engagement with the clevis coupling (#36). Set the
transmitter on the meter head and position the driven clevis shaft
(#28) so that the slot in the clevis coupling (#36) is properly engaged
with the cross pin in the driven clevis shaft (#28). Secure the four
mounting screws (#37) .
12. TRANSMIT TER WIRING can be accomplished by following the
applicable wiring diagram on pages 13 and 14.
TRANSMITTER
OPERATION AND MAINTENANCE MANUAL
V. MCCROMETER products have been carefully designed to be as main-
tenance free as possible. Periodic preventive maintenance, however,
is highly recommended and should be practiced according to schedule
to assure continuous accuracy and trouble free performance of your
transmitter. The maintenance and inspection procedure can also be
used as a guide to locating a problem in the unit that may be the
cause of abnormal operation.
VI. WORKING AREA chosen for cleaning and inspection of the internal
components should be clean to reduce the chance of dust or dirt
particles being introduced into the transmitter mechanism.
VII. TOTALIZER ASSEMBLY (#4) service procedure should include
cleaning and inspection of the unit noting any excessive wear on the
change gears (#7 & #8) that may lead to operational problems in the
unit.
1. BONNET MOUNTING SCREWS (#3) should be removed and
the entire bonnet (#1) lifted o of the meter.
2. TOTALIZER is contained within the totalizer bonnet (#1) and
held in place by a base cup (#5). It should not be necessary to remove
the totalizer (#4) during inspection; however, removal of the base cup
(#5) is necessary for inspection of the totalizer change gears (#7 &
#8). Removal of the base cup (#5) can be accomplished by inserting
a small screwdriver into the two cutouts and prying upward under the
edge.
3. TOTALIZER CHANGE GEARS (#7 & #8) should be inspected
for any sign of wear. Both the A-(drive) gear and B-(driven) gear are
attached to the lower portion of the totalizer assembly (#4). Spin the
oating totalizer driven magnet in the center of the totalizer bottom
(#4) to make certain it spins freely without bind or drag. The bottom
of the totalizer has the letter “A” molded next to the A-drive gear
shaft, and the letter “B” next to the B-driven gear shaft.
4. TOTALIZER DRIVE MAGNET ASSEMBLY (#9) located in the
transmitter base (#10) at the top of the driven clevis shaft (#28)
should be checked and adjusted if necessary to position it 1/16 inch
below the top surface of the transmitter base (#10). Adjustments
can be made by loosening the socket head set screw in the side of
the totalizer drive magnet assembly (#9), and sliding it up or down
the driven clevis shaft (#28) as desired. Always be sure the set screw
is tightened into the at on the driven clevis shaft (#28).
‡VIII. INDICATOR-TOTALIZER service procedure should be practiced yearly
and should include removal, cleaning and inspection of the unit noting any excessive wear on the gears and other wear points that may
lead to operational problems in the unit.
‡ For Indicator-Totalizers Only
30119-33 Rev. 1.8/04-14
‡ For Indicator-Totalizers Only
‡ For Indicator-Totalizers Only
‡1. BONNET MOUNTING SCREWS (#2) located beneath the
indicator-totalizer bonnet lid, should be removed and the entire bonnet (#1) lifted o of the transmitter. Replace the o-ring seals around
each of the four screws (#3) and at the bottom of the bonnet (#4) and
cover each of the new o-rings with a thin coat of silicone grease.
‡2. INDICATOR MOUNTING SCREWS (#6) and shake-proof wash-
ers (#7) holding the indicator-totalizer unit (#5) to the transmitter
base (#10) should be removed and the unit lifted o, exposing the
A-drive gear (#8) attached to the top of the driven clevis shaft (#28).
‡3. METER CHANGE GEARS (#8 & #9) should be inspected for
any sign of wear. The A-(drive) gear (#8) is attached to the top of
the driven clevis shaft (#28), and the B-(driven) gear (#9) is attached
to the bottom of the indicator (#5). The position of the A-drive gear
should be checked and adjusted if necessary to position the top face
of the gear 1/8 inch below the top surface of the transmitter base
(#10). The position of the B-driven gear top face should be 1/8 inch
below the bottom of the indicator-totalizer.
‡4. INDICATOR-TOTALIZER unit (#5) should be cleaned thoroughly
using a mild soap and a soft brush. Under no circumstances should
the entire unit be immersed in the soap or should any metal object be
used when cleaning and inspecting the internal parts of the indicatortotalizer unit.
‡5. GEARS within the indicator-totalizer unit (#5) should be
inspected carefully. If any excessive wear is visible on the gear teeth,
and other wear points, the unit must be returned to McCrometer for
repair.
IX. INSPECTION of all internal parts that may be replaced in the eld
has been accomplished at this point. Should any of the parts upon
inspection, appear to be damaged or excessively worn, they must be
replaced to assure proper operation and prevent further damage.
X. REASSEMBLY is necessary at this point. Before reassembling, make
certain that the unit is cleaned of any dust or dirt. Cost for replacement parts not covered by warranty are available from current parts
and price list. If it is determined that the unit should be returned for
repair, please notify McCrometer prior to shipment. Each unit must
be properly packaged to prevent damage to the unit in shipment.
1. TOTALIZER DRIVE MAGNET ASSEMBLY (9) should be checked
again to make certain it is properly set to drive the totalizer (#4). (See
step VII- 4).
2. TOTALIZER BASE CUP (#5) can be placed back in the totalizer
bonnet (#1) on the totalizer assembly (#4) after the desiccant capsule
and the base cup o-ring (#6) are replaced and the new o-ring (#6) has
been covered with a thick coat of silicone grease. Be sure o-ring (#6)
is on base cup (#5) properly. When reinstalling the cup (#5), put two
drops of super glue on the inside edge of the bonnet 180° apart and
push cup rmly into the bonnet and hold for 30 seconds.
3. BONNET ASSEMBLY (#1) should be cleaned and replaced on
the transmitter (#10). Bonnet o-ring (#2) should be replaced and the
new o-ring (#2) covered with a thin coat of silicone grease. Secure
four screws (#3).
‡4. CHANGE GEARS (#8 & #9) should be checked again to make
certain they are in proper alignment (see section VIII-3). The gear
teeth should be lubricated with a light grease to assure longer life.
‡5. INDICATOR TOTALIZER mechanism (#5) should be placed on
the transmitter base (#10) with the mounting screws and shakeproof
washers (#6 & #7). Do not tighten mounting screws (#6) until the
gear mesh has been properly adjusted. To adjust gear mesh, slide
the indicator-totalizer mechanism (#5) towards the A-drive gear
(#8) until the unit stops because of full gear mesh. Now back o the
indicator totalizer mechanism 1/64 inch and tighten mounting screws
(#6).
‡6. BONNET ASSEMBLY (#1) should be cleaned and replaced over
the indicator-totalizer unit (#5) after replacing the desiccant bag.
Secure four screws (#2) beneath the bonnet lid. Do not over tighten
the mounting screws (#2) as this will result in damage to the screw
o-rings (#3).
XI. TROUBLESHOOTING the transmitter is necessary if it is apparent that
the instrument being controlled by the transmitter is not receiving a
proper signal from the transmitter, and/or the totalizer or indicatortotalizer is not functioning. Before beginning, it is important to be
sure that the problem is with the transmitter, therefore, the following
checks should be made. 1) Check to be sure that water is owing
through the meter at ows above the minimum ow rate for the
given size meter. 2) Check the instrument to be sure it has the
required power being supplied to it. 3) Check the junction box to be
sure the communication lines from the transmitter to the instrument
are making good contact and that the transmitter is wired properly
to the instrument.
1. THE TROUBLESHOOTING GUIDE is provided to help isolate any
problem that may occur with the transmitter. Follow the instructions
and test procedures listed for each problem.
A. If the meter totalizer or indicator-totalizer does not work, but
the remote instrument does operate (receiving the proper signal),
then see section VI, VII-1 thru 4, IX and X-1 thru 3 for checking the
totalizer, or section VI, VIII-1 thru 5, IX and X-4 thru 6 for checking the
indicator-totalizer.
6
30119-33 Rev. 1.8/04-14
7
B. If the meter totalizer or indicator-totalizer does work but the
remote instrument does not operate (not receiving proper signal),
then use troubleshooting procedures #2 thru #4 and #8 thru #11.
C. If the meter totalizer or indicator-totalizer and remote instru-
ment do not operate, then use troubleshooting procedures #2 thru
#11.
2. WORKING AREA chosen for testing and inspection of the
internal components should be clean to reduce the chance of dust or
dirt particles being introduced into the transmitter mechanism.
3. TOTALIZER OR INDICATOR-TOTALIZER must be removed from
the transmitter base (#10) and inspected for damage (see section VII
for removal and inspection of the totalizer or section VIII for removal
and inspection of the indicator-totalizer).
4. MOISTURE should not be apparent within the transmitter base
(#11) chamber. All o-rings should be inspected for breaks or presence
of foreign materials that allow leakage to occur. Check to be sure
water is not coming up through the meter head. If water is coming
up through the meter head then the meter should be checked (see
meter service manual).
5. DRIVEN CLEVIS SHAFT (#28) should be turning if water is
owing (above minimum ow rates) through the line. If water is
not owing through the line, then the transmitter base assembly
(#10) must be removed from the meter head and the driven clevis
shaft (#28) turned by hand. If water is owing, but the driven clevis
shaft is not turning, then the transmitter base assembly (#10) must
be removed from the meter head and the drive clevis (#35) must be
checked.
6. TRANSMITTER BASE (#10) can be removed by removing the
four transmitter base mounting screws (#37). Lift the unit carefully
o the meter. (Sometimes the transmitter sticks to the meter so
it may be necessary to separate the joint by using a sharp knife or
putty knife as a pry.) Be sure not to damage the transmitter base
(#10) or the clevis (#35). Note: After the transmitter base (#10) has
been removed, the meter assembly should be inspected thoroughly
to be sure it is operating properly (vertical shaft turns when water is
owing through the line) and is not the cause of the problem (refer
to your meter service manual for instructions on inspection of the
meter).
7. DRIVE CLEVIS (#35) and the drive clevis coupling (#36) should
be checked for damage and checked to be sure they are at the proper
elevation and are engaging properly with the driven clevis shaft (#28)
(see section IV-9). If the clevis (#35) or coupling (#36) is damaged
then they are the likely cause of the problem and must be replaced
(see section IV-9 for installation of new clevis). If the clevis (#35) and
coupling (#36) are adjusted correctly and engaged properly with the
driven clevis shaft (#28) but the meter is not turning them, then the
meter is the likely cause of the problem.
8. SWITCH ACTUATOR (#23) is a black plastic slotted cup located
below the circuit card (#12). The actuator (#23) should be turning
(with water owing or driven clevis shaft turned by hand) when the
driven clevis shaft (#28) is turning. If the actuator (#23) does not
turn when the driven clevis shaft (#28) turns, then the transmitter
gear train is damaged and must be returned to the factory for repair
(see section XIII for return of transmitter to factory). If the actuator
cam (#23) is turning then the communication lines (#39) and printed
circuit card (#12) should be checked.
9. TRANSMITTER COMMUNICATION LINES (#39) should be
checked to determine the current level owing in the loop. The
method of measurement is to insert a multi-meter into the 4-20 mA
loop by disconnecting one of the mA signal wires, clipping one side
of meter to disconnected wire and connect other end of multimeter
to the lug or post from which the wire was removed. (mA wires are
red and green.)
If no water is owing through the meter, the current level should
be 4.0 mA. The purpose of the 4.0 mA at no ow, is to insure that
the loop is complete. If there is 4.0 mA in the loop when no water is
owing, then the loop is intact.
If water is owing through the meter, the current level should be
between 4-20 mA, depending on ow.
10. PRINTED CIRCUIT CARD (#12) should be checked to be sure
it is functioning properly. The circuit card (#12) may be checked as
follows:
WARNING: COVER TOP OF TRANSMITTER SO BRIGHT LIGHT OR
SUNLIGHT DOES NOT INTERFERE WITH NORMAL OPERATION
PRINCIPLES OF OPTIC SWITCH.
A. If the current level in the loop is 0.0 mA, check the voltage
between the mA terminals at the transmitter card. It should be at
the maximum power supply level (± 1.0 VDC).
If there is no voltage present, then check the loop voltage at its source.
If there is voltage at the voltage source then there is an opening in the
loop.
If there is no voltage at the power supply, disconnect loop and check
supply by itself. If the voltage level is still 0 VDC or very low (<10
VDC), replace power supply.
B. If the level of current is greater than 20 mA, there are two pos-
sibilities. The card may be starting to fail, but unless there has been
some major damage done to the card (physical impact or voltage
levels above 50 VDC applied), it should not exceed 25.00 mA.
High loop current can also be caused by a short in the trans-
mitter hookup cable. A zero ohm short will cause power supply fuse to blow. However, it is possible to have a shunt of
about 0.5Ω to 10Ω connecting transmission lines, which
will cause excessive loop current with transmitter in the
system (from 70.0 - 350 mA or more) but when the P. C.
30119-33 Rev. 1.8/04-14

meter (if it was necessary to remove it), see section IV - 10 and 11.
The totalizer assembly or indicator assembly must be reinstalled on
the transmitter base, see section X - 1 thru 3 for totalizer and section
X - 4 thru 6 for indicator.
1. BEFORE RETURNING TRANSMITTER TO FACTORY, please
notify McCrometer prior to shipment. Each unit must be properly
packaged to prevent damage to the product during shipment. Should
any of the unit’s parts, upon inspection, appear to be damaged or excessively worn, they must be replaced to assure proper operation and
prevent further damage. Cost for replacement parts not covered by
warranty are available from current parts and price lists. Should the
unit require further inspection, it must be reassembled and returned
to the factory.
XIV. PROCEDURES FOR CHECKING OUT INOPERATIVE INSTRUMENT
SYSTEMS.
NOTE: The 4-20 mA loop must be powered if the pulse output is used.
All instruments are factory tested with the transmitter that will be
operating it. When an instrument doesn’t operate and it is connected
to its proper transmitter, certain procedures need to be followed to
determine where and what the problem is. Most troubleshooting
procedures are part of each instrument and transmitter service
manual, but these suggestions may help.
1. CHECK ALL INSTRUMENTS AND TRANSMITTERS for obvious
visual damage.
2. CHECK YOUR INSTRUMENT to be sure it is operating properly
by following the instrument service manual. Check to be sure your
instrument is operating correctly when a simulated signal is put into
it. WARNING: Circuit to transmitter must be disconnected when
most testing equipment is used for checking your instrument. If
instrument checks out, proceed with checking transmitter and communication lines.
3. WHEN THE TRANSMISSION OR COMMUNICATION LINE is
suspected of being the reason the system is not functioning, it is
usually easier to check out the transmitter rst to be sure it is giving
proper output. There are some easy troubleshooting techniques to
be used. First, you must know what signal is expected from the
transmitter.
A. Standard Model TR15 & TR16 current transmit-
ters have an output of 4-20 mA at maximum scale of the
board is tested separately, it works ne. These shorts are dicult to
nd. They can be caused by incorrect wiring installation or damage
to present wiring. Damage can be caused by physical contact (back
hoe, etc.) or from environmental eects (water in the raceways).
C. If transmitter output remains at 4.0 mA even when the actuator
cup (#23) is rotating and the transmitter is away from direct sunlight
or other high energy light source, replace the circuit card (#12).
If the loop current is within a satisfactory range, 3.00 mA - 23.00 mA,
and varies with a varying ow rate, but is not within accuracy at any
given ow, then all that is needed is calibration. The 4-20 mA loop
current should only be adjusted as described under BENCH CALIBRATION.
D. BENCH CALIBRATION can be accomplished using the following
equipment:
Power supply - well regulated, 10-30 (24V STD).
Multimeter - must be better than 0.5% accuracy on 0-20 mA range.
Model CN09 - use test gears required for transmitter gearing.
1) Mount the transmitter on the CN09 calibration unit.
2) Hook-up the circuit as shown on the bench calibration wiring
diagram.
3) Adjust the zero potentiometer so that the multimeter reads 4.00,
±.02 mA.
4) Set CN09 to 75%, adjust the span potentiometer to 16.00 mA, ±
.02 mA.
5) Check the output at the 25% (8.00 mA) and 50% (12.00 mA) set-
tings on the CN09 to verify circuit linearity.
6) Reinstall the transmitter onto the meter after calibration is com-
plete.
11. REPLACING PRINTED CIRCUIT CARD (#12) can be accom-
plished in the following way: Turn the power for the transmitter o
at the instrument. Disconnect the communication wires from the
terminal strip on the circuit card (#12). Remove the three circuit card
mounting screws (#15) and washers (#16). Lift the circuit card (#12)
out of the transmitter base. If your transmitter is equipped with an
indicator-totalizer, then the A-drive gear (#8) set screw may have to
be loosened and the A-drive gear (#8) removed in order to remove the
circuit card (#12). Place the new circuit card (#12) in the same position
as the old circuit card and secure it to the support posts with the three
screws (#15) and washers (#16). Replace the indicator A-drive gear
(#8), if it was removed (see section VIII-3). The communication lines
should be attached to the terminals on the circuit card (#12) (see wiring
diagram). Be sure to route the communication lines connected to the
terminal strip away from the totalizer drive magnet (#9) or indicator
A-drive gear (#8). These rotating parts within the transmitter can
damage the wires.
XII. INSPECTION and eld testing has been accomplished at this point.
Should any of the parts, upon inspection, appear to be damaged or
excessively worn they must be replaced to assure proper operation
and prevent further damage. If the transmitter still does not work
then it should be returned to the factory for repair.
XIII. REASSEMBLY is necessary at this point. Before reassembling make
certain that the unit is cleaned of any dust or dirt. Cost for replace-
ment parts not covered by warranty are available from current parts
and price list. The transmitter base should be reinstalled on the

G. Pulse outputs from the transmitter can be checked by several
dierent types of digital counters. We will explain how our standard
Model IN16 remote totalizer can be used.
See the wiring diagram (see page 11) to hook up your wires correctly
by connecting the black wire clip to the pulse - (black outlet wire),
and the red clip to the pulse + (white outlet wire) inside the transmitter or on the same wires as they go into the instrument.
If there is no pulse output from the transmitter, check the power
supply voltage for transmitter (24 VDC). If the voltage is present at
the transmitter circuit board then the circuit board could be faulty.
If there is no voltage present, then the communication lines or
power supply could be bad. Check the power supply voltage at the
instrument. Check to see if the power supply is fuse protected before
replacing power supply. Also check for loose connections at the
terminals. Be sure transmitter is wired correctly to instrument. Be
aware power must be connected to the recorder so the 12 or 24 VDC
will then power the transmitter to operate the optic switch, which we
will be checking out.
After the IN16 is attached and you have your stop watch ready it is
very simple to reset the counter. Hold the button down and release
it at same time as you start the stop watch. When the stop watch is
approaching 60 seconds, be prepared to read the counter at exactly
when 60 is reached or disconnect one of the IN16 wires to stop it from
counting any more.
If the counted pulse rate matches with calculations done in Section
XIV # 4 - E and the instrument checks out per Section XIV - 1 and 2,
then the trouble is probably the communication line.
5. COMMUNICATION PROBLEMS can be so complex it is usually
recommended the instrument contractor or electrical contractor be
informed that our transmitters and indicators prove to be good units
and the trouble could be elsewhere. Sometimes it is necessary to
lay another line from the transmitter to instrument above ground to
help prove the lines are at fault prior to pulling and replacing existing
line. Communications lines should be kept from tangling up in high
voltage lines inside the panel or wiring cabinet. Communication lines
should be shielded cable and not run in same conduit as power lines.
Sometimes the 115 VAC line used for the instrument can be causing
the trouble. It is suggested the plug from the instrument be temporarily transferred to another AC outlet which is on another circuit. It
has been found a uorescent light circuit tied in with the instrument
power source, or faulty parking lot vapor lights can eect the instruments if AC wiring is done incorrectly to give a noisy AC circuit.
instrument it operates. They also have an optional 150 PPM pulse
output.
B. The original purchaser of the equipment should have invoices
or other paperwork to inform you what the 4-20 scale is. If these are
not available, you can phone the factory and furnish the meter serial
number and the transmitter record can be pulled to give you the full
scale information.
C. Let’s assume you found the meter was a 12” meter and the full
scale of the instrument is 3000 GPM.
4. FULL SCALE OUTPUT. Now we know what the output at full
scale is supposed to be from the transmitter, so now let’s nd out
what it actually is.
A. We need to nd out what the ow rate going through the meter
actually is.
B. Time the transmitter totalizer test or sweep hand with a stop
watch for 1 to 5 rotations, to give the best resolution or closest accuracy.
C. The example meter has a 1000 gallon totalizer and if you time
the sweep hand for three revolutions in 150 sec, proceed as follows:
150 sec ÷ 3 rev = 50 sec for 1000 gallons (1 rev)
D. To nd the true ow rate:
60 sec ÷ no sec per rev x totalizer dial
or as shown below
60 ÷ 50 x 1000 = 1200 GPM true ow rate
If the meter is furnished with a Model CN06 ow indicator, now is the
time to verify the indicator is accurate.
E. To determine what output the transmitter should be sending,
we must now nd what percent 1200 GPM is of the 3000 GPM scale
stated earlier.
1200 GPM ÷ 3000 GPM = 40%
1. Model TR15 & TR16 current output (4-20 mA).
Because 4 mA equals ZERO it must be subtracted from
20 mA.
Therefore, 20 - 4 = 16 mA usable output (SPAN)
40% x 16 mA = 6.4 mA then add 4 mA back to give 10.4
mA @ 1200 GPM.
2. 150 PPM at full scale, so 40% x 150 PPM = 60 PPM
@ 1200 GPM.
F. 4-20 mA current signal can be checked by using a digital
multimeter. Have the multimeter set to measure milliamps. With no
water owing through the meter the ammeter should measure 4.0
mA. If water is owing through the meter the current level should
be between 4-20 mA.
NOTE: Power should be removed from circuit before inserting the
multimeter. The multimeter must be connected in series with circuit
being tested.

6. SEPARATION OF SIGNAL AND POWER wiring in separate
conduits is the traditional precaution, however, other measures must
be taken to minimize the eects of electromagnetic interference
(EMI) and radio frequency interference (RFI) on the operation of the
instrument. Otherwise, if high level, short duration, noise spikes are
permitted to enter the digital equipment, the noise can be transferred
into the systems logic networks and can be misinterpreted as signal
data, resulting in erroneous system operation and other unpredictable responses. Potential noise sources: Relay coils, solenoids, AC
power wires, current carrying cables, or radio frequency transmissions.

NOTES:
Maximum current consumption of transmitter is 20 mA. Units which are provided
with only 2 output wires may be rewired for 150 ppm pulse output by stripping
back the insulation on both ends of the output cables and wiring as shown above.
Wire Size Information:
The distance of the communication line from transmitter to the device the 4-20mA
will operate depends on the loop resistance, the wire size, and the power supply.
Based on a 24V DC power supply and 22 gauge wire, we recommend a maximum
loop of 5,250 feet.
