IN THE EVENT OF A GAS LEAK
In the event of a large gas leak:
Evacuate the area and notify the fire department or oth-
er appropriate authorities.
In the event of a small, contained gas leak:
Isolate and stop the leak
Prevent accidental ignition
Prevent entrance of gas into other portions of the build-
ing. Be aware that LPG is heaver than air and will seek
lower levels
Evacuate all people from the danger zone
See that the gas is dispersed before resuming the busi-
ness and operations. If in doubt, notify your local authorities.
IN THE EVENT OF A GAS FIRE
In the event of large fires or fires that are spreading:
Evacuate the building and notify your local fire department.
Stop the leakage only if you can safely reach the equipment.
The meters non-shock maximum operating pressure is indicated on the meter name plate. The meter should never be
operated in excess of this pressure. Care should be taken
to eliminate thermal and hydraulic shock conditions, so that
they do not exceed the meters maximum working pressure.
In the event of small, contained fires that you can safely
control:
Stop the leakage if you can safely reach the equipment.
Then use the appropriate extinguisher: Class B fire extinguisher, water, fog, etc. depending on the equipment. If in
doubt, call your local fire department.
3
Installation & Operation
Installation:
Before Start-up of the Meter, make certain:
The meter is properly mounted, secured and piped
All shipping plugs are removed and lines are clean of all
debris.
All connections are tight and there are no leaks
All bleed and drain valves are closed
Do NOT smoke near the meter, or use the meter near
an open flame when metering flammable fluids. Fire or
explosions could result.
This meter is not intended for use with fluids for human
consumption.
*** Install the Meter and Accessories in Compliance with all applicable local, state and federal
construction, electrical and safety codes. Additionally, the LPG meter must be installed in accordance with the requirements of ANSI-NFPA 58
Make sure that all necessary safety precautions have been
taken including proper clothing, personal safety equipment
and fire safety equipment if required.
Before shipment, protective thread caps were placed in the
meter and accessories openings for protection. They should
remain in place until your are ready to attach the piping.
The meter must always be securely bolted to a platform or
supporting member, regardless of the mounting position.
Never “hang” a meter on the connecting pipe.
Position the meter with service in mind. Provide ample work
space. Removing covers can be difficult when work space
is not available. Always supply a platform or support for the
meter mounting.
Prior to meter installation, the entire piping system should be
thoroughly flushed of all debris with a liquid that is compatible with the construction of the meter.
Keep all external surfaces of the meter clean.
Positive displacement meters are designed to operate full o f
liquid. The meter should be installed in a manner such that
it remains full of liquid at all times.
Install the companion flanges. Tighten to a position that
allows the meter to bolt to the companion flanges, free of
pipe stress. The meter should always be supported by bolting to a platform. Never use the connecting pipe as the
means of support.
In critical installation, block valves and by-pass lines
are recommended. This allows the meter to be serviced without interruption of flow in a critical process
application.
Thermal and or over pressure relief valves are recommended and should be installed w henever it is possible to block the meter between two valves. Thermal
pressures many times the operating pressure are possible with only a small rise in temperature.
It is recommended that a strainer be installed upstream of
each meter to prevent damage from foreign matter such as
weld slag, pipe scale, etc.
A means to calibrate and prove the meter should be provided during installation. An easy means for diverting flow into
a calibration vessel should be considered.
Hydraulic shock like thermal expansion can be harmful
to the meter components. Consideration should be
given to designing pumping and piping systems to
eliminate hydraulic shock.
WIRING
If the flow meter is part of a dispenser, please refer
to dispenser manufacturer wiring diagram.
If the flow meter is used as a ‘stand-alone’ dispens-
ing meter, please refer to:
Page for TS06A with ELNC register
Page for TS06A with EMR register
Page for TS06A used with other registers
Operation Requirements:
Upstream lines must be maintained full to prevent air from
entering the meter. If the upstream or inlet lines are constructed in a manner which allows reverse flow, foot or back
check valves should be installed.
Underground tanks that are furnished with a submersible
pump will eliminate many problems that occur with positive
displacement pumps with suction pipes when the suction
piping is incorrectly sized creating too large a lift.
4
Installation & Operation continued
Every meter should be calibrated under actual service and
installation conditions. Follow your local Weights and
Measures recommendations.
Provide a means of conveniently diverting liquid for calibration purposes.
Give careful attention to your system’s pumping equipment
and piping because of their influence on the liquid being
measured as it enters the meter assembly. Systems should
be made free of conditions that cause or introduce entrained
air or vapor.
Follow the manufacturer’s recommendation fully when installing pumps. Give particular attention to factors like: use
of foot valves, pipe size to the inlet and conformance to net
positive suction head (NPSH) conditions when suction
pumping is required. Following the manufactures’ recommendations will minimize air and vapor elimination problems.
Torque Chart
Start-Up:
Fill the system slowly to avoid operation on air or vapor.
This can be accomplished in the following manner:
Throttle the meter inlet valve, and allow the meter and pip-
ing to fill slowly by gravity.
Crack open the outlet valve and start the pump, then slowly
open the inlet valve until the system is up to pressure. Open
the outlet valve fully to establish full flow. Check the flow
rate to assure the meter is operating within specified rates.
The meter is not designed to operate on air, but the design
and materials of construction of the TUTHILL meter allows
for operation on vapor for short periods of time without damage to the elliptical gears or other meter internals.
Note: Over- speed and hammer caused by the presence
of vapor in the system can cause internal damage to the
meter.

Installation & Operation continued
Theory of Operation;
The TUTHILL meters LPG metering system combines an
oval gear positive displacement meter, differential valve,
strainer and vapor eliminator in one assembly. The differential valve incorporates a piston type construction with the
piston moving away from its seat when at least 15 PSI pressure (above product vapor pressure) is maintained at the
meter outlet. The soft seat valve assures measurement
accuracy by requiring pump operation for delivery, by requiring adequate back pressure to prevent product vaporization
during measurement and by requiring blockage of flow whe n
the vapor eliminator release valve is open. The strainer
prevents foreign particulate from entering and damaging the
meter. The meters close tolerance machine construction
and no metal to metal contact provides accurate liquid
measurement.
Installation, Flow Meter:
Install the meter assembly in a dispenser cabinet, or a truck
deck to a secure base using the bolt holes on the “feet” of
the strainer assembly base. Make inlet and outlet connections at the flanged surfaces on the strainer and differential
valve, respectively. Leave a minimum of 12 inches be-
tween he strainer flange and any obstacle for servicing
the strainer.
Installation, Vent Line:
The vent line from the meter’s vapor vent to the vapor spac e
on the supply tank should a minimum of 1/4” inside diameter
tube or pipe. A shutoff valve must be installed in the vapor
vent line to allow removal of the strainer or service on the
meter. The vapor release vent line must be returned to the
vapor space of the supply tank and normally should not be
made common with the other vapor return lines or pump by-
pass lines.
When properly installed, this line must permit free flow in
either direction. If the vent line is closed the meter will not
function, as the differential valve will not open. These instructions must be followed to maintain proper function of
the differential valve.
Support:
Prevent pipe strain or stress from occurring when making
connections to meter or accessories and during repairs.
Pipe strain and stress occurs when the pipes are not supported or are not aligned correctly to the meter. The weight
of the pipes must always be supported independent of the
meter. This meter and accessories can easily be removed
without affecting the pipes or the pipe alignment. Never
leave any of the pipes hinging.
Storage:
If the meter is used for seasonal work, at the end of each
season the meter should be removed from the system and
thoroughly flushed with a compatible liquid. This includes
removing the drain on the front and rear covers. Then flush
the product from the front and rear covers. If flushing with
water is preferred, extra care should be taken to drain the
meter completely and to dry all internal parts. Immediate
refilling with a compatible liquid (or oil misting) is essential to
prevent corrosion as well as ice damage to parts from moisture that was overlooked after flushing and drying.

Flow Meter Maintenance
Danger!! Danger!! Danger!!
Relieve all internal pressure before servicing.
Line pressure must be 0.0 PSI
Serious injury or death from fire or explosion could result from maintenance of an
improperly de-pressurized and evacuated system.
Preparing for Service:
Close the belly valve of the supply tank.
Close the valve on the vapor return line.
Close the manual valve in the supply line on eh inlet
side of the meter. If no manual valve exists on the inlet
side, consult the dispenser manufacturer on installer for
procedures to depressurize the system.
Slowly open the valve/nozzle on the end of the supply
line
After product is bled off, close the valve/nozzle at the
end of the supply line.
Open the bleed valve provided by your installer to re-
lieve the system pressure. Product will drain from the
meter system.
As product is bleeding from the bleed valve, slowly reo-
pen and close the valve/nozzle on the discharge line.
Repeat this step until the product stops draining from
the bleed valve and discharge line valve/nozzle.
Leave the discharge line valve/nozzle open whil e work-
ing on the system.
General Service:
Do not scratch or mar any of the precision machined
surfaces by prying or sanding parts.
Torque specifications. All fasteners such as screws and
bolts should be torqued to proper specifications. See
the “Torque Chart” in this manual.
Stone the machined surfaces when reassembling the
meter to assure the machined surfaces are free of burrs
and scratches.
Removing flange seals: When removing the flange
assembly, always carefully remove the O-ring seal.
Make sure that the flange surface is clean. Discard and
replace the old O-ring seals if it is nicked or scratched in
any way. It is undamaged, it can be re-used.
Examine all fasteners: make sure fasteners are not
bent, rusted, or have pulled or burred threads. The
threads should all appear evenly placed. If the bolts are
bent, check the housing and cover for flatness. Use a
straight edge to determine flatness. Use a stone to
remove any burrs on the flat surfaces for the housing.
Look for gaps: When disassembling a meter, use a
feeler gauge to check for gaps between the post and
gear plates and housing. If you do find gaps, check the
plates for flatness with a straight edge. Gaps can be
caused by shock problems that must be resolved. Contact your full service distributor, or the Service Department at TUTHILL meters for assistance if this occurs.
Check the O-Rings: O-rings should be smooth.
Cracked or worn O-rings should be replaced. However,
a more serious problem of shock my have occurred if
the O-rings are nibbled or extruded. Shock problems
must be verified and resolved. Contact your full service
distributor, or the Service Department at TUTHILL meters for assistance if this occurs.
Check the post and gear plates: Check the plates for
flatness. Use a straight edge. Warped plates can be
caused by hydraulic shock problems that must be resolved. Contact your full service distributor, or the Service Department at TUTHILL meters for assistance if
this occurs.
Weights & Measures: Check with the regulatory agenc y
that governs Weights and Measures in your area. Removing a seal wire may require Weight & Measures
recalibration.
Repair pulled threads with threaded insert fasteners.
These can be used in many instances. Contact your full
-service distributor for advice if this occurs.
Coating threads: When removing and replacing bolts
and screws in a meter, always coat the threads with anti
-seize.

no damage to the meter cover (22), it is possible to replace the meter using the existing meter cover. In this
case it is not necessary to disconnect the outlet wiring.
Remove the four bolts (23) and the SCL housing (22).
Install a new oval gear set (17) if necessary. Gears
should be perpendicular to each other. The gears will
not rotate a complete revolution if not installed properly.
Once installed, the gears should rotate freely with out
binds or rubs. Check the clearance between the gears
and the body. There should be a minimum of .003 inch
between gears (17) and the meter cover (22). If there is
any binds or rubs between the gears and the meter
body, it is recommended that the meter be replaced.
Reinstall the meter cover (22).
Reinstall the differential valve.
It is recommended that all O-rings and seals be re-
placed during service, but a good inspection is critical if
seals are reused.
Calibrate the meter and return to service.
Inspect the internal parts for wear. Gear may be re-
placed at this point if all other components are good.
Remove the bolts ( ) and remove the differential valve.
Remove the four bolts (20) and the meter assembly
(body (19) and post plate (14).
Clean all surfaces using a brush or fine (200 grit) emery
cloth.

dirt which may cause the valve to stick. The valve
should slide freely without any signs of sticking. There
should be no scratches or burrs on the valve assembly.
Replace if there are signs of damage.
Inspect all seals, and replace if damaged or brittle.
Re-assemble the meter in the opposite direction making
sure all bolts are torqued to the proper specifications.
Inspect the seals for wear or damage. Replace worn or
brittle seals.
Reassemble the valve and install in the strainer hous-
ing. This valve is optional and will not retrofit into strainer housing not originally supplied with the valve.
Reassemble the system making sure bolts are torqued
to the proper specifications
Strainer Service: (See page 8)
Remove the four bolts (37) from the rear cover and re-
move the cover (7).
Inspect the seal (12) and replace if damaged or brittle
Remove the strainer (10). Clean the strainer with low
pressure air, blowing out all loose sediment. Wash the
strainer with solvent.
Inspect the strainer for holes or other damage and re-
place if necessary.
Re-assemble making sure the bolts are torqued to the
proper specifications.
Vapor Eliminator Service: (See pages 8 & 11)
Disconnect the vapor return line flange and the differen-
tial valve tubing.
Differential Valve Service (see page 11):
Remove the outlet piping flange.
Remove the connecting tube between the differential
valve and the vapor eliminator.
Remove the Screws (1) securing the cover (2) from the
valve body (4).
Remove the differential valve piston assembly (8) and
spring (7).
Inspect the valve body and cover for damage. Clean all
surfaces of dirt or deposits using a fine (200 grit) emery
cloth if necessary. If damage is more than superficial,
replace the valve.
Inspect all seals and replace any brittle or damaged
seals. It is recommended that all seals be replaced
during service.
Replace the U-Cup seals (8a). Note proper positi on of
the seals. Use a small amount of Teflon lubricant to
help install the seals.
Replace the square cut seal (8b). Use thread sealer
(Locktite Blue) when installing the fastener (7e).
Re-assemble the valve in the opposite manner.
Remove the five bolts (3) from the vapor eliminator
housing.
Remove the cover (4) from the vapor eliminator hous-
ing.
Remove the float and valve assembly (34) from the
cover for inspection.
Inspect the float for damage or leakage. A crack will
allow the float to fill with liquid and sink thus prevent the
valve form closing. A collapsed float is an indication of
over pressure or hammer and these operation conditions must be corrected before reusing the meter.

Trouble Shooting
Problem
Leakage from seal cover.
Product flows through meter but the register does not operate
Breaking teeth on gears.
No flow or low flow through the meter
Probable Cause and Solution
Seal has been damaged due to shock
Cover bolts have not bee tightened sufficiently
Replace seal and /or re-torque bolts
Pulser is not functioning properly
Meter gears are jammed and not turning
Replace the pulser, inspect internal meter parts
Starting or stopping flow too rapidly.
Normal wear after long service
Replace gears
Correct system operation
Check pump by-pass setting.
Faulty non-functioning pump
Differential vale not open or not functioning. Replace valve
Meter “frozen” due to build up of salts or frozen material. Clean meter
internals and inspect for damage
Vapor vent line valve shut or obstruction in vapor vent line. Open valve
or remove obstruction
Strainer dirty and plugged. Clean Strainer
U-Cups on differential valve leaking. Replace U-Cups
Meter operates too slowly:
Product flows through the meter but register does not record properly:
Differential valve internal mechanism faulty. Valve does not open full y.
Meter gears or rotors partially “salted”, enough to slow the rotating
gears. To correct, clean gears.
Strainer partially plugged. Clean strainer basket.
Pump not functioning properly. Repair pump
Pulse output board faulty, or not calibrated for electronic register.
Vapor release valve sticking.
Differential valve leaking.
Repair or replace as necessary.

SCL & Pulser Assembly
SCL (Scaler/Calibrator/Linearizer)
Description: Tuthill SCL is a small electronic device designed to provide the function of a pulse Scaler, an electronic Calibrator and Linearizer. This electronics package
replaces a mechanical gear plate and mechanical calibrator
while at the same time providing the ability to improve the
accuracy of a metering device during low flow operation,
thus improving the overall meter accuracy, and extending
the flow range of the metering device. The SCL may be
used in conjunction with other Tuthill electronics to solve
many of your electronic interface requirements.

OPERATION:
The SCL may be used to perform a number of functions
depending upon the users application. The following is a
brief description of several of the SCL functions.
SCALER MODE:
When operating in the Scaler mode only, the SCL app lies a
single error correction factor (ECF) to the incoming pulse
signal. If a single correction factor is applied to the entire
range of meter frequency inputs then the output frequency is
proportional to the input frequency times the ECF (SCL
Pulses out = SCL Pulses in times ECF). If the ECF is 1.0
(no scaling factor) the output frequency is equal to the inp ut
frequency.
As an example, use this feature when the customer’s electronics requires a precise frequency or pulse resolution input. If the customer’s electronics required 100 pulses per
liter, then 100 PPL becomes the base pulse resolution
based on which all input pulses are scaled. If, as an example, the meter is providing 108 pulses per liter, then an ECF
of 0.925 (100/108) would be programmed into the SCL, and
the output pulse frequency would be equivalent to the selected base resolution of 100 PPL.
LINEARIZER MODE:
If a metering device is not producing an output within the
limits of accuracy required for an application, the SCL may
be used as a linearizer. A linearizer is a device, which recognizes the output frequency of the metering device, and
applies a correction factor (ECF), chosen for that frequency
to improve the accuracy of the metering device.
The number of ECF points chosen for a specific application
depends upon the accuracy of the metering device. In
weights and measure applications, there is an ECF applied
at each flow rate point where the meter accuracy varies by
0.25% from the previous flow rate point.
The ECF data is stored electronically in the SLC at the facto-
ry . The electronic chip storing this data is permanently attached to the printed circuit board. The ECF chip is marked
with a code, that is used to reference the exact set of ECF
data, that is supplied in your SCL device.
CALIBRATOR MODE:
The SCL is equipped with two rotary switches S3 and S4,
and a two position switch S2. The three switches allow the
SCL to adjust the pulse output up or down by 3%.
This allows the operator, or W&M authorities to calibrate the
meter without having to alter scale factors in customer electronics. This feature is designed to replace mechanical calibrators used in the field for years to adjust the meter output
to accurately match the volume in a proving vessel.
The calibrator feature may be used if the SCL in being used
as a scaler only, or as a scaler/linearizer.
SWITCHES:
S1 : Allows the choice of either a single channel input,
or a two channel quadrature input.
S2 : Is used in conjunction with S3 and S4.
If in the minus (-) position, an increase in the S3 and
S4 switch settings will decrease the pulse output. A
decrease in pulse output will increase the volume in
a prover vessel. If in the plus (+) position, an increase in the S3 and S4 will increase the pulse output. An increase in pulse output will decrease the
volume in the prover vessel.
S3/S4 Adjust the SCL pulse output up or down +/-3.0%.
S3 and S4 will allow for 00-99 settings. Each increment changed in this setting, changes the SCL
pulse output by approximately 0.03%

Flow Meter Calibration
Y
METER CALIBRATION:
Flow meter re-calibration should be on a volume
equal to 1 minute of flow at maximum flow rate.
All tests should be performed 3 times under identi-
cal conditions to confirm repeatability.
Maintain a permanent file fo r each flow meter, and
record % change each time the meter is recalibrated.
When the change is significantly higher than that
found in previous re-calibrations, it is time to rebuild the flow meter (replace the two oval gears).
METER CALIBRATION:
The calibrator allows you to adjust the outpu t of the SCL up
or down, like a mechanical calibrator, +/- 3% in increments
of 0.03%.
After calibrating a known volume (X) into an accurate
prover (or through a master meter with adequate resolution), compare with register reading (Y) and calculate
correction:
To reduce the volume in a prover vessel (can), place
switch S2 in the plus(+) position.
X-
X
x 100
= % correction
Adjust the S3 and S4 to the position required for the
necessary volume reduction in the prover can. Switch
S3 and S4 represent readings of 00 to 99, and each
increment will adjust the output approximately 0.03%.
Example:
Using a 20 gallon (75.7 liter) can, the can reads 113.5
ml high. The meter error is (113.5/75700) = 0.0015
or .15%. To adjust the meter output, place S2 in the
positive position, and set S3 and S4 to read 05. This is
approximately a 0.15% adjustment.
Activate the Reset push button switch to enter the new
program settings. Retest the flow meter.
To increase the volume in the prover vessel. Place
switch S2 in the negative (-) position, and set switches
S3 and S4 to the proper settings to adjust the output.
Activate the Reset push button switch to enter the new
data.
NOTE: If S2 is in the plus (+) position, and S3 and S4
are at 15 as an example, then moving the posi
tion of S3 and S4 to 00 will provide a (0.03 x 15)
=.45% increase in the prover volume. To obtain
a greater increase in the prover volume, S2
must be placed in the minus (-) position and S3
and S4 rotated to the proper position to obtain
the desired change in pulse resolution. The
opposite is true if S2 is already in the minus (-)
position at the beginning of calibration.
Finally:
Re-seal the flow meter.
Enter date and % correction on the permanent flow
meter record.
As long as degree of change is moderate, the flow meter is
in good condition.
If there is a sudden significant jump in correction required,
the rotors are likely about worn out. Rotor replacement
should be considered now, rather than letting further wear
cause rotors to start rubbing on flow meter housing.
METER CALBRATION: INCREASED PRECISION.
The standard method for calculating the single point adjustment is to obtain the error as a percentage of the desired
test volume. In the previous examples, an excess volume in
the prover vessel of 113.5 ml became 0.15% and the adjustment was 05 on S3 and S4.
However, the 0.15% correctly needs to be applied to the
nominal ECF for the particular meter profile in order to more
precisely calculate the adjustment for S3 and S4. The nominal ECF is the particular profile base divided by the natural
meter pulse resolution.
As an example, a meter type which is scaled to 100 ppl and
has 410 ppg pulse resolution, has a nominal ECF of
378.5/410 = 0.9232. 0.15% of 9232 is 13.84. When divided
by 3, the switch setting is 04.6. In this example, 4.6 is
rounded up to 05. This is the same result as before because the ECF is close to unity (1.0000). If the ECF was
0.4200, then the switch setting would be 02.
There are applications where the nominal ECF is not near
unity. In those cases, the nominal ECF needs to be known
and used for the calculation. If the standard calculation is
used, the adjustment would be excessive and the meter
technician would have to estimate the reduction in his settings and perform an additional test run.
