1 Introduction
1.1 Warranty
Instruments are guaranteed for twelve months for the date of delivery. Warranty cover only
defective parts and faulty workmanship and doesn't cover defects due to wearing, dirt,
modification and alteration of the instrument not authorized by Isoil Impianti SpA. Warranty is
given free of charge ex our works. Warranty of instruments and accessories not
manufactured by Isoil Impianti, will be covered by warranty of the sub supplier. Warranty is
valid only if original spares are used and is invalidated in case of improper use or not
following the technical specification of the instrument. Only Isoil Impianti SpA has the right to
decide if the warranty can be applied. If the purchasing order calls for different warranty
conditions, above stated conditions are surpassed.
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.
Special tools have been designed to facilitate overhaul operations and their use is
recommended. Reference to the tools is included in the next pages.
Fig.1
Also make sure that all electric or electronic part, if present, are
disconnected from its power supply.
The installation of the meter counter does not require any special procedure; just pay
attention to the following points:
• The meter counter BM can be installed horizontally (fig.1) or vertically;BMV version
vertically only (dwg.6977). In both cases 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 (40 mesh for oil, 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
downstream the same meter.
CAUTION
If the line pressure can reach values higher than the maximum
allowed, automatic safety valves must be installed in adequate
places. It is necessary to avoid the pressure meter exceeds the
maximum high pressure showed on the meter plate.
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.
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.
Fig.1 Fig.2
6. Extract the rotor paying attention to use the free hand to guide the rotor and control the
lateral vanes movement.
4.2 Assembly
Before assembly, clean and inspect all parts for any visual damage. Ensure that all o-ring
grooves are clean and undamaged. Examine the O-Rings and ensure that they are not
damaged or swollen, replace them if necessary. Examine graphite bushes on rotor assembly
for free rotation and play, replace them if either is apparent. Examine each vane assembly
for damage or wear, replace vane(s) if either is apparent. Examine gland seal rings in rotor
assembly for damage or wear and replace if either is apparent.
The assembly procedure is the reversal of the dismantling procedure; only for installation of
the internal body special precautions should be taken to match the centering cap of the
external body's front cover.
The square key (5) and l the stop pin (4) are always supplied whether the p.d.meter has a
mechanical counter.
NOTE: one complete turn of the screw (6) varies the volume indicated on the meter by
approximately 0,18% (per cent).

4.4 Suggested lubricating oil for calibrating
mechanism
To allow proper lubrication of the gear wheels on the housing is essential to fill the
box with lubricating oil, using the black plug on the side of the box.
Make sure that the level oil upper the sight glass.
In the Table 1 you can choose the lubricating oil if you know the using temperature
SAE 0W-30
SAE 5W-30
SAE 10W-60
SAE 15W-40
SAE 10W-40
SAE 10
SAE 10W
SAE 0W
The oil is suggested by ISOIL, for standard application is SAE10, for a range temperature
(from –10° to +60°C); to avoid ice forming in win tertime, add two spoons of car antifreeze.
4.8 Storing
• if after a working period it is foreseen to stop the meter for a long time, drain the
meter and its accessories;
• If the meter or the equipment of the system are not immediately used, or if it is
withdrawn from service and stored, it is important to follow next instructions :
• fill the meter and its accessories with clean kerosene or lubricated oil and close its
ends with blind flanges;
• fill the carter containing the calibrating mechanism with oil till the sight glass is
reached
• adequately protect counters against rain and dust, with damp-proof caps
