1 Introduction
1.1 Warranty
Each device comes with a 1-year warranty, starting from the delivering date.
Such warranty of good operating of the equipments includes our efforts of repairing or
replacing, in the shortest time, the parts that fail for defective manufacturing or material
during the warranty period, without rights to any refund for damages or other expenses.
If a device is going to be transferred in our laboratory for repair, the delivery expenses is at
the customer’s expense.
For any inspection of our qualified personnel related to what stated above, the labor is at our
expenses, while the board, lodging and travel expenses are in charge at the customer.
The components furnished and installed, but not produced, by Isoil
Impianti S.p.A.are covered by the guarantee released by the respective producers.
The warranty ceases if non-original spare parts are used; the warranty ceases too for an
improper use or if the operational limits of the device are exceeded.
1.2 Introduction
ISOIL positive displacement meters are precision measuring instruments designed for use
with a variety of petrochemical products and liquids. Each meter is fully tested and calibrated
by factory before dispatch, and a regular service will maintain a high standard of
performance and accuracy.
P.D. meters must be periodically tested by a calibrating tank, Prover, or Master Meter: if out
of accuracy a service is necessary.
Experience has shown that mechanical defects are usually caused by the entry of foreign
matters into the metering compartment due to inadequate straining facilities in the pipeline.
1.3 Working principles
Liquid enters the meter through the manifold and causes the rotor to revolve by pressure on
the vanes. The proximity of the rotor to the front and rear of the casing forms an efficient seal
while the profile of the casing guides the vanes on to the measuring crescent.
The seal between vane and body is assured by the combined effects of gravity and
centrifugal forces of vanes and it is assured the self-balance of clearances generated by the
use too.
The rotor spindle extends through a pressure tight seal in the meter front cover into the
calibrating mechanism which transmits the rotor movement to the register. (fig.1)

CAUTION
All parts under pressure must be released before disassembling
the meter or its accessories for adjustment, inspection, servicing or
substitution of its components.
Also make sure that all electric or electronic part, if present, are
disconnected from its power supply.
2 General safety principles
This operator’s manual contains basic safety instructions that must be followed during
system installation, operation and maintenance. Failure to comply with these instructions
may result in personal injury and can lead to personal, industrial or environmental accidents.
Some examples of possible hazards caused by non-compliance with these instructions are:
•Failure of the system and/or some components.
•Hazards to people caused by the exposition to electrical, mechanical or chemical
influences.
•Pollution of the environment through the leaking of hazardous substances
Therefore, follow the safety instructions described in this manual; in case of uncertainties,
please contact the manufacturer.
2.1 General instructions
•Read carefully the operator’s manual.
•Make sure that all the personnel assigned to the installation, operation and
maintenance is properly trained.
•Make sure that the contents of the operator’s manual are completely understood by
all personnel assigned to the operations on the system.
•Inspect parts under pressure in compliance with national regulations before the initial
operation of the system.
•Make sure that the operator’s manual is readily available to personnel on site
•Follow national safety regulation in force in the location of the plant.
•Make sure that the system operates in compliance with the relevant operational limits.

adequately trained personnel.
•The meter must be used for the purpose it is made for; the manufacturer is not
responsible for any damage deriving from uses outside of the original purposes.
•The meter must be operated inside the limits fixed by the manufacturer; the
manufacturer is not responsible for any damage deriving from uses outside of the
operational limits of the device.
2.3 Instructions for the operator
•The operator must adhere to safety and accident-prevention standards currently in
force in the country where the device is installed.
•The operator must not, by his own initiative, carry out any operation that is outside his
competence.
•The operator must carefully comply with hazard and/or prohibition instructions
contained in this manual.
•Do not use petrol, solvents or other flammable substances to clean parts. Use only
approved commercial solvents that are non-flammable and non-toxic.
2.4 Servicing instructions
•Never carry out any maintenance, servicing or regulation before having closed the
root valve, discharged the pressure from the system and disconnected the power
supply to any electrical device (if present), unless explicitly stated otherwise.
•Read carefully the rating plates on the individual equipment.
•All maintenance operations, either ordinary or extraordinary, must be done by
authorised and trained personnel.
•The maintenance operator must wear clothes adequate to the working environment
and to the situation; in particular, loose or voluminous clothes, chains, bracelets, rings,
earrings or anything that might get caught in the mechanical parts of the system
should be avoided.
•The maintenance operator must wear adequate protective devices in accordance with
safety and accident-prevention regulations.
•In explosive environments use only antisparking equipment.
•If the meter is connected to any electric or electronic equipment, disconnect all of
them from the power supply before doing any servicing or regulation operation, unless
explicitly stated otherwise in the manual.
2.5 Operating precautions
•The meter must be calibrated following the instructions reported into the operator's
manual and in what stated into the Manual of Petroleum Measurement Standards
(API) with particular attention to the following chapters:
- Chapter 4: proving systems
- Chapter 5: metering
- Chapter 6: metering assemblies
- Chapter 11 section 2.3: water calibration of volumetric provers
- Chapter 12 section 2: calculation of petroleum quantities
•The meter must always remain full of product; to achieve this, it is suggested to install
the meter so that it remains below the main line.

Isoil impianti SpA Page 7
All rights reserved. Reproduction of this manual is forbidden. Code MA038/00/EN/03
•The line upstream the meter must be kept full of product to avoid that some air enters
the meter.
•Each meter must be adjusted following the instructions supplied in the operator’s
manual.
•Follow the recommendations of the manufacturer when installing pumps. Pay
particular attention to factors such as the use of foot valves, inlet pipes dimension and
conformity with NPSH when there are suction pumps. Follow the recommendations of
the manufacturer to minimize the problems due to air and vapors.
•For flashing liquids (quick gasification of the liquid) or easily vaporizing liquids at high
environmental temperatures, e.g. light hydrocarbon, it is advisable the use of
submerged aspirations and pipes larger than the nominal dimension of the pump.
•Thermal expansions that generate overpressures can easily damage the meters and
the systems in general. Put safety valves for overpressure in every section that can be
closed through regulation or isolation valves.

CAUTION
All parts under pressure must be released before disassembling
the meter or its accessories for adjustment, inspection, servicing or
substitution of its components.
Also make sure that all electric or electronic part, if present, are
disconnected from its power supply.
3 Installation
3.1 Precautions
The installation of the meter counter does not require any special procedure; just pay
attention to the following points:
•The meter counter must be installed horizontally, the rotor axis must be kept
horizontal.
•All the meter’s openings are protected with covers when shipped; those must not be
removed until the meter is installed on the piping
•Before the installation of the meter, it's suggested to clean thoroughly the piping to
remove dirt, crusts and other foreign particles.
•Piping should not exercise strain on the meter. The meter is designed for overhang
and supports should be provided only on the adjacent pipes.
•Leave space enough around the meter to ease access for adjustment, servicing and
disassembly. The counter, if present, must be easily readable.
•The meter must always remain full of product; it's suggested to install the meter so
that it remains always under the main line.
•The line upstream the meter must always remain full of product to avoid that air
enters the meter's measure chamber; if the pipe arrangement allows reversal flow, a
non-return valve must be installed.
•Flow through the meter must be regular and uniform; pulsating and irregular flows
must be avoided.
•It is recommended to install flow limiting valves downstream of the meter if the flow
rate can reach values higher than the maximum allowed for the meter.
•If the line pressure can reach values higher than the maximum allowed, automatic
safety valves must be installed in adequate places.
•To protect meter from damages due to foreign particles in the liquid, a suitable
strainer with a correct mesh number (60 mesh for diesel oil, 100 mesh for gasoline)
must be installed upstream the meter.
•In case the rate of flow through the installation exceeds the meter maximum rated
capacity, it is advisable to use a flow limiting valve, which must be installed

Isoil impianti SpA Page 9
All rights reserved. Reproduction of this manual is forbidden. Code MA038/00/EN/03
downstream the same meter.
•Water must not flow through the meter.
•Meters must be installed in such a way that air or vapour do not enter through the
liquid under measurement. It is always suggested to install an air separator just
upstream the meter.
•To avoid hammer shocks which may strongly damages the meter, it is not advisable
to install upstream or downstream the meter any quick closing valves.
•It is recommended to install root valves at the inlet and outlet to ease servicing
operations and isolation of the meter
3.2 Start-up precautions
•Before proceeding with the start-up make sure that:
- The meter is adequately fixed
- All the connections are tightened
- Air is bled from the pipes
•If a calibration mechanism is associated with the meter, before the start-up it must be
filled with lubricating oil
•Vent out all the air eventually present in the line
•When the meter is operated for the first time, fill it slowly with the operating fluid by
following this procedure:
- Open slowly the upstream isolation meter or fill the meter by gravity
- Open slowly the downstream isolation meter letting the flow rate rise smoothly to
the operating value
CAUTION
Be very careful when starting up the meter: if the air enters the
measuring chamber the rotor can easily reach high rotational
speeds, leading to abnormal wear of the vanes and other
components; this, in turn, will lead the meter to a major failure.

Page 10 Isoil impianti SpA
Code MA/038/00/EN/03 All rights reserved. Reproduction of this manual is forbidden
CAUTION
All parts under pressure must be released before disassembling
the meter or its accessories for adjustment, inspection, servicing or
substitution of its components.
Also make sure that all electric or electronic part, if present, are
disconnected from its power supply.
4 Maintenance
Before removing the flow meter from the pipeline for repairs, it is recommended that the
possible causes and corrective actions are noted with the help of Fault Diagnosis Chart given
in this manual.
Note that certain components in the flow meter assembly are not interchangeable. Therefore,
if more that one flow meter is dismantled, it is recommended that each flow meter is
dismantled independently.
CAUTION: Be very careful when you start up the meter after maintenance: if the air enters
the measuring chamber the rotor can easily reach high rotational speeds,
leading to abnormal wear of the vanes and other components; this, in turn, will
lead the meter to a major failure. See chap.3.2 for start-up procedures.
4.1 Disassembly
The flow meter may be considered as two main assemblies: the measuring chamber and the
calibrating mechanism. To separate these two assemblies from each other, remove the
screws securing the calibrating mechanism on the flow meter body.
CAUTION: Before dismantling the meter for maintenance release pressure from the line
and drain all the fluid inside the meter through the draining hole below the
meter.
Proceed then with the maintenance of the faulty part.
4.1.1 Main components disassembling
1. Remove Spring Dowel (30) fitted across the Rotor spindle.
2. Rest the flow meter body horizontally on bench.
3. Remove 6 Nuts (5) from the Front Cover (7).
4. Remove Front Cover and collect O’Ring Seal (9) and Shim (26) fitted inside.
Note : Do not remove Spindle Seal from the Front Cover, unless it is defective. The
defective seal is indicated by product leakage between the Front Cover and
the Calibrating Mechanism. If it is necessary to remove the seal, take out the
Snap ring (1) and Backing Washer (2), which secure the Spindle Seal into the
Front Cover, and then the seal can be withdrawn.

4.1.2 Rotor disassembling
Remove the rotor assembly in a smooth vertical lift. Collect washer (28) from the Rear cover
NOTE: Do not remove the vanes unless they are damaged; if their substitution is
necessary:
•remove the split pins (11) fitted on the opposite side of the vane adjusting nuts;
withdraw the vane blade (10) from the assembly and collect washers (13) and
springs (12); withdraw the remaining vane blades with vane rods; remove screws
(20) and collect gland clamps (19) and gland seal rings (17).
CAUTION: Don't remove or loosen the the vanes adjusting nuts(21-22), since that would
vary the clearance between the vanes and the measuring chamber, causing
loss of performance and/or meter failure.
4.2 Calibrating mechanism (only for mechanical
counter)
The calibrating mechanism comprises a train of gears which transmit movement of the rotor
to the counter. Operational failures of the mechanism are rare and they generally regard the
breaking of tension pin, due to an excessive strain.
It is recommended to repair without varying the calibrating adjustment.
CAUTION: do not remove the shimming washers between the frame and the bearing of the
mechanism box.
Fig. 1
This chapter only applies for mechanical counter; for the calibration of the meters with
electronic counter please refer to the specific manual.

4.2.1 Calibration of flow meter
The calibrating mechanism comprises a train of gears which transmit movement of the
rotor to the counter. Operational failures of the mechanism are rare and they generally
regard the breaking of tension pin, due to an excessive strain.
It is recommended to repair without varying the calibrating adjustment.
Attention: do not remove the shimming washers between the frame and the bearing of the
mechanism box.
To carry out meter calibration follow next procedures:
•Break and remove seals.
•Remove the three screws (1) securing the cover (2) to the housing (3) in which
calibrating mechanism is fitted.
•Remove cover (2)
•By using square key (4 mm) turn shaft (4) till A, B, C holes placed on the bracket (5)
and on friction roller (6) will be properly aligned.
•Insert in these holes the stop pin (supplied with the meter, then using the square key
operate on the shaft (4) as follow :
- turning counter-clockwise direction, even if the quantity of fluid does not vary, on
the counter is obtained an higher volume indication;
- turning clockwise direction it is obtained a lesser indication.
NOTE: one complete turn of the screw varies the volume indicated on the meter by
approximately 0,36% (per cent).

4.4 Strainer/air eliminator (optional)
The strainer removes all solid impurities from the liquid before it reaches the meter and the
Air eliminator removes entrapped air from the liquid.
The strainer is mounted on the upstream side of the meter.
The air eliminator is mounted centrally on the top of the top of the fabricated steel body of
strainer.
4.4.1 Strainer(Fig.2)
A clean strainer is fundamental for the correct operation of the system; a dirt strainer would
create an excessive pressure drop, leading to the failure of the basket and thus letting dirt,
crusts and other harmful elements to flow into the fluid. If possible, check regularly the
pressure drop between the inlet and the outlet of the strainer; the maximum allowed pressure
drop is 130 kPa.
The basket (2) which is made of stainless steel wire mesh is positively clamped by the end
cover and nut (5,23) a drain plug is provided for draining of liquids inside.
For a correct servicing of the strainer, follow the procedure described below:
•Discharge the pressure from the system and close the valves at the inlet and outlet
•Open the drain plug
•Remove the end cover (5) with o-ring seal (4)
•Remove and clean the basket; if possible, use a water cleaning machine
•Check accurately that the basket is intact; if it is found to be damaged, replace with
another one with the same filtering grade:
- For diesel oils: 60 mesh (247 micron)
- For gasoline: 100 mesh (153 micron)
•Remove and inspect o-ring seal for visual damage, if the rubben sealing rings need
replacement, remove the damaged rings and replace with a news o-ring
•Put again the basket in place, close the cover and the drain plug.
It's suggested to replace the o-rings between the strainer body and the cover each time the
strainer is disassembled.
4.4.2 Air eliminator
The valve assembly (air vent valve) consists to stainless float connected to the main valve
via multiple linkages (11,12,13). Main valve sits against rubber sealing ring (20) and seals
the air eliminator chamber from atmosphere. Main valve slides in guide provided in bracket
(10). Bracket is clamped to the cover plate (9) by socket head screw (27). An o-ring seal(21)
is provided between body and cover plate.
Follow the instructions below for the servicing of the air eliminator:
•Discharge the pressure from the system and close the valves at the inlet and outlet
•Discharge the liquid through the drain plug
•Remove nuts (22) and lift the cover. Collect o-ring seal.
•Remove screws (27) and remove bracket from cover plate.
