Essential Instructions for Measuring Equipment, Including the
European Union (Directive 2014/32/EU MID)
Although measurement transducers are not
specifically included in the MID regulations as they
do not form a complete measuring instrument
system, in accordance with Article 1 and 4, Annex
I and Annex VII, Brodie Meter Co., LLC implements
the same stringent regulations for all products and
tests to the same standards which are used for
complete measuring instrument systems.
The complete system must contain all the
necessary components to meet the requirements
of the local regulations. These components may
include pumps, air eliminators, strainers, valves,
flow computers, etc. The unit must be sealed in
accordance with the local regulations; it is the end
user’s responsibility to ensure this happens.
Flow measuring devices are provided with two
labels which specify flow ranges. The name plate
label, which includes the factory serial number,
details the operating flow range. This is the flow
range the device will operate within without
causing damage. The custody transfer label details
the working flow range associated with a particular
weights and measures approval.
It should be noted that these may not be the same;
therefore, in trade applications, the flow ranges
specified on the custody transfer label should be
followed.
Essential Instructions for Electrical Equipment, Including the
European Union (Directive 2014/30/EU and 2014/32/EU)
This unit contains Electrostatic sensitive circuit
boards. Electrostatic safety precautions should be
taken to prevent damage.
When connecting wiring it is good practice to use
shielded cable. The shield should be connected to
earth at the read out or control systems end of the
cable; the other end of the shield should not be
connected.
This wiring practice is mandatory in order to
comply with the requirements for electromagnetic
compatibility as per the EMC directive 2014/30/EU
and MID 2014/32/EU of the council of the
European Union.
It is the end user’s responsibility to ensure that all
protective covers are in place to prevent electrical
shock and/or personnel injury.

Page 6/58IOM BiRotor Plus R27
Essential Instructions for Pressure Containing Equipment,
Including the European Union (Directive 2014/68/EU)
When installing the equipment the bolting must
conform to the requirements of ASME B16.5,
paragraph 5.3, and to the material requirements of
ASME B16.5, Table 1B. Gaskets must conform to the
requirements of ASME B16.20.
Although it is not expected for the device to
be used in a service where it would come in to
contact with unstable fluids, it is the end user’s
responsibility to assess any risks and take any
precautions necessary.
It is the end user’s responsibility to ensure that
piping and other attachments connected to the
Brodie instrument do not place adverse stresses
upon it, the design of the instrument has not
been assessed for the effects of traffic, wind or
earthquake loadings.
It is the end user’s responsibility to ensure that the
instrument is mounted when required on suitable
supporting foundations.
It is the end user’s responsibility to install the
device in a well-designed system to avoid potential
hazards such as water hammer, vacuum collapse
or uncontrolled chemical reactions.
It is the end user’s responsibility to provide fire
protection measures and equipment in accordance
with the local regulations.
It is the end user’s responsibility to install suitable
straining and air/gas elimination systems.
The instrument has been designed without
allowance for corrosion or other chemical attack.
The end user should implement a periodic
inspection and maintenance program to ensure
that none of the instruments pressure containing
components have been subject to any corrosion. It
is possible to examine the instrument for evidence
of corrosion through the inlet and the outlet.
When the ambient temperature is below the
minimum operating temperature specified on the
device it is the end user’s responsibility to ensure
that the device is warmed to an appropriated
temperature before being pressurized.
Do not exceed the operating pressure and
temperature limits of the instrument as stamped
on the nameplates.
It is the customer’s responsibility to install this
equipment in a system that provides adequate
over-pressure protection and that limit pressure
surges to 10% of the maximum allowable working
pressure of the instrument.

protection measures and equipment in accordance
with the local regulations.

IOM BiRotor Plus R27Page 7/58
Essential Instructions for Equipment to be Used in Hazardous
Locations, Including the European Union
(Directive 2014/34/EU)
Any Hazardous area approval applies to equipment
without cable glands. When mounting the
flameproof enclosure in a hazardous area only
cable glands/conduit seals certified to meet or
exceed the rating of the equipment should be
used, refer to the type approval documentation
for further details. Cable glands and cable must
be suitable for the operating temperature of
the device under its rated conditions, this is
especially important if the device has an operating
temperature above 1580F (700C). It is the end
user’s responsibility to ensure this happens.
The meter has been provided with an approved
sealing device in one of the cable entries, the other
entry has been closed with a plastic cap plug. It is
the end user’s responsibility to remove the cap plug
and replace it with a suitable cable gland or conduit
seal before the equipment is put into service.
It is the end user’s responsibility to ensure, when
the instrument is located in a hazardous area, that
all cable glands and conduit seals are installed in
accordance with all local codes and regulations.
It is the end user’s responsibility to ensure that
before opening an electronic enclosure in a
flammable atmosphere that all the electrical
circuits have been interrupted.
If replacement of the screws which secure the
sensor housing, the UMB cover of the electronic
register and its cover, are required, they must be
replaced with either factory direct parts or M6-1x16
(6g) mm hex head socket screws of equal length.
The screws must be made from stainless steel
grade A1-70 or A2-70 and be torqued to a value of
55 inch lbs. upon installation. It is the end user’s
responsibility to ensure this happens.
It is the end user’s responsibility to assess the
maximum surface temperature of the device
and the equipment the device is attached to
and located next to as this may exceed the
temperature ratings of the device itself. If this
happens, additional safety precautions will need to
be implemented by the end user.
Flame proof housings contain Aluminum; although
the composition of these enclosures is carefully
maintained to prevent any risk of an ignition source
it is the end users responsibility to ensure that the
housing is not struck by rusty tools or objects.
If the equipment is to be installed in an area where
dust deposits and build up are to be expected, a
maintenance plan should be arranged to include
regular removal of the dust build up. This will prevent
the dust from forming a possible source of ignition.
The power supply requirements for this
product are specified within the operating
and maintenance manual, it is the end user’s
responsibility to operate the product within these
specified limits.
The instrument may contain surfaces that
constitute flames paths, these surfaces should
not contain any mars or scratches. Damaged
flamepath surfaces may not be repaired. If
any damage is present, the factory or the local
representative should be contacted immediately
to obtain a new housing as the safety of the
enclosure may be impaired and must be replaced.
It is the end user’s responsibility to inspect these
surfaces every time the enclosure is opened.
When flanged flame paths are reassembled the
gap between them should be less than 0.0015”
(0.038 mm) such that a 1/2” (12.5mm) wide
0.0015” (0.038 mm) feeler gauge will not enter
the gap more than 1/8” (3mm). It is the end user’s
responsibility to ensure this happens each time the
enclosure is reassembled.

4 Receipt of Shipment
When you receive your equipment inspect the
outside of the packing case for damage which may
have incurred during shipping. Damage incurred
during shipment is the responsibility of the carrier
and is not part of the factory warranty. If the
packing case is damaged, notify the local carrier
immediately.
If the package is in good condition remove the
envelope containing the packing list and carefully
remove the equipment and all components
included in the shipment from the packing case.
Inspect for damaged or missing parts, referring to
the packing list, and prior to discarding the packing
material.
If Items are missing from your shipment, contact
your sales representative. Your sales order number
will be required.
5 Return of Equipment
If the equipment must be returned to the factory
for repair or replacement, a Returned Materials
Authorization (RMA) must be included with the
components.
RMA forms may be obtained from your sales
representative or from the Product Service
Department.
In addition to the RMA, a Material Safety Data
Sheet and a Decontamination Statement must be
included with Items being returned to the factory.
A Decontamination Statement is included in the
back of this manual.
If the equipment is removed from service it must
be thoroughly drained and neutralized before it is
packed for shipment. Care must be taken to ensure
that product removed from the equipment is
disposed of in accordance with all applicable local,

6 Storage
Brodie International instruments are precision
devices and should be handled and stored with
care. They should not be subjected to rough or
improper handling or stored in an environment
where moisture, extreme temperatures, or foreign
material can damage the meter.
The inlet and outlet flange covers should remain
on the instrument until the unit is ready for
installation.
If extended storage is required it is
recommended that the instrument be placed in an
environmentally controlled warehouse.
If this is not possible the instrument should be
stored in a waterproof lined wooden box. Desiccant
packs should be taped to the inside of the
instrument end connections before they are sealed
to reduce the effect of humidity on the equipment
and accessories. Caution must be used to ensure
desiccant packs are removed prior to installation.
Depending on the storage time it may also be
preferable to use a compatible corrosion inhibitor.
If the meter is removed from service for an
extended period of time it should be flushed with a
light oil before being placed into storage.
7 Description
General
The BiRotor Plus is an extremely accurate,
dualcased, flow measuring device. It produces a
high resolution signal, via the use of non-wetted
pick offs, which is directly proportional to the rate
of liquid flow through the meter. These signals
can be shaped by a simple pre-amplifier for
transmission to ancillary equipment.
The BiRotor Plus meter utilizes the exclusive
BiRotor principle. There are no sliding, oscillating,
or reciprocating parts.
The BiRotor Plus (models B27X, B28X, B29X,
B30X, B31X, B32X, B33X, B34X, B35X, B36X, B38X,
SB25X, LB27X, LB28X, LB29X) electrical enclosure
comprises of a cast aluminum body and a plain lid
containing a PCB which consists of an inductive
proximity sensor which detects metallic objects
without coming in direct contact. Two entry holes
are provided on one face of the enclosure to allow
the fitment of suitable cable entry devices. A
closed cell silicon rubber compound sponge gas-
ket is fitted around the top of the enclosure, onto
which the lid is fitted. The lid is held in position
with four socket head screws. A warning label is
fitted on the lid and held in place with four rivets
secured into blind holes.

8 Installation and Operation
General
The operation of the meter is embodied in the
function of the measuring rotors; they are always
dynamically balanced but hydraulically unbalanced
during operation. The rotors have no metal to
metal contact with each other or the housing in
which they rotate. Clearances between moving
components are maintained with the use of timing
gears.
The BiRotor Plus is a positive displacement (PD)
meter. A PD meter uses a mechanical principle that
measures flow by continuously dividing the flowing
stream into known volumetric segments, isolating
those segments momentarily, and then returning
them to the flowing stream while counting the
number of displacements. This is a direct volume
measurement, there is no inferred, or software
generated, measurement.
8.1 - Installation Requirements
1. The instrument should be mounted on a
secure foundation. Provisions should be made
for vertically mounting the meter to ensure
stability.
2. The process piping should not place any undue
strain on the instrument.
3. Precautions should be taken to ensure that
thermal fluid expansion does not raise the line
pressure above the maximum working pressure
of the instrument.
4. Process piping must be clean and free of any
foreign matter.
5. A strainer should be installed upstream of the
instrument.
6. An air eliminator should be installed upstream
of the instrument if the process fluid is
expected to contain entrained air.
7. A flow limiting valve should be installed
downstream of the instrument, this will
maintain a back pressure on the instrument
and prevent excessive flow rates.
8. Isolation valves should be located at either
ends of the instrument run and a bypass
section installed. This will facilitate ease of
component removal, when required, and
reduce loss of product.

Page 16/58IOM BiRotor Plus R27
8.2 - Installing the Instrument
1. Remove the inlet and outlet protection covers.
2. Install the instrument into the pipe work
using suitable hardware as specified in the
local codes and regulations. Ensure that the
connections are made tight and torqued to the
correct values.
3. Connect the instrument wiring, refer to Figures
9-1 and 9-2. Cable entry into the electrical
enclosure is by two 3/4-14 NPT female threads.
All flame paths must be protected from
damage during work.
4. Use wiring appropriate for the location and
operating conditions. Wiring glands and/or
conduits must conform to local electrical codes
and regulations if wiring is to be installed in a
hazardous area.
NOTE:
For additional requirements on installation please
refer to Chapter 2, Essential Instructions, at the
beginning of this manual.
If the instrument is being installed with additional
accessories, the instructions for those accessories
should be read and understood before continuing
with the installation. The output signal from the
preamplifier, if one is fitted, can be altered to
interface with most electronic accessories. This is
accomplished by the use of jumpers on the circuit
board. Refer to Figure 8-1 for their configurations.
The UMB housing may be rotated in 90°
increments to accommodate the mounting of
accessories. If the UMB housing is removed for
any reason, the flame path at the base must not
be damaged. No repair is allowed if the surface is
damaged. Care must also be taken to disconnect
the sensor wires to prevent damage. It is
essential that the four retaining screws used to
secure the UMB housing to the meter body be
torqued to 55 in/lbs.
Internal grounding terminal must be used for the
equipment grounding connection, and the external
terminal is for supplementary bonding connection.
Grounding symbol congruent to IEC 60417 number
5019 located on the grounding connection to UMB.

The instrument should not be located in a location
where excessive vibration is to be expected.
Care should be taken not to locate the instrument
near any source of electromagnetic interference, such
as those produced by electric motors, transformers,
solenoids, etc.
Either of these factors could induce a signal into the
flow sensing pickoff and interfere with the accuracy of
line product measurement.

functions and wiring possibilities please refer to
the BERT-E’s instruction manual.
8.3 - Meter Start Up and Operation
Review the system installation to ensure all the
components are in proper sequence, all isolation
valves must be closed, all electrical connections
are complete, and all covers are in place.
1. To pressurize the system, slowly open the
inlet valve so as to prevent system shock.
Slowly allow product to enter the system while
keeping the downstream isolation valve closed.
2. Open the downstream valve (10%) to allow
any air to be flushed from the system. Do not
overspeed the instrument.
3. Once the air has been flushed from the system,
close the downstream isolation valve and check
for any leaks. If leaks are found, check all seals
and retighten connections.
4. Fully open the upstream isolation valve to
pressurize the system.
Flow start up can commence once the system has
been pressurized.
1. Turn on all electronic circuits and check for
proper function.
2. Open flow control valves and allow the
instrument to run at 20% of its rated flow for 5
minutes.
3. During this initial run, check all other
components in the system for functionality.
4. Once this run is complete, set the flow control
valve to the required flow and ensure that
the maximum flow for the instrument is not
exceeded.

IOM BiRotor Plus R27Page 19/58
8.4 - Higher Temperature Start Up
On higher temperature start up above 212°F
(100°C), based on an ambient temperature of 70°F
(21°C), special start up procedures are required to
prevent damage to the flow meter components.
A similar procedure should be followed on any
thermal shock in excess of 176°F (80°C). The
following equation may be used to determine the
approximate flow meter warm up time.
th= [(Cnom )∙ (OT°f - 212)]/100
th= Warm Up Time in Hours
Cnom = Nominal Connection Size
OT°f = Operating Temperature in °F
During this warm up time the meter should be
operated at approximately 5% of maximum flow to
allow the temperature to stabilize.
8.5 - Custody Transfer
A meter factor will need to be established under
actual operating conditions if the instrument is to
be used in custody transfer applications. This inital
proving run should be carried out following the
completion of the meter start up procedure, and in
accordance with local regulations.
NOTE:
There are no user adjustable parts in these
instruments, however, the instrument housing is
provided with two cross-drilled bolts and drain
plugs to facilitate sealing if required by the local
weights and measurements regulations.
