BM Series Flowmeters, hereafter called flowmeters, are
positive displacement meters that measure extremely low flows of clean
liquid with high accuracy . The flowmeter generates an electrical signal
proportional to flow for use with a wide variety of electronic
instrumentation.
The flowmeters have incorporated the oval rotor principle into its design.
This has proven to be a reliable and highly accurate method of measuring
flow . Exceptional repeatability and high accuracy over a wide range of
viscosities and flow rates are features of the flowmeters.
The low pressure drop and high pressure rating means the flowmeters are
suitable for both gravity and pump (in line) applications.

To provide for optimum system performances the following guidelines
should be observed:
1. Before use, confirm the fluid to be used is compatible with the meter .
2. The flowmeter must be installed so the shafts of the rotors are
horizontal, never vertical or “on end”. Severe damage to components
may be the result, (See Figure 2-1).
3. A mesh strainer should be installed upstream and adjacent to the
flowmeter to protect it from foreign matter such as dirt, pipe scale,
or welding splatter.

2-7 Pre-Operation Procedures
Section 2 Installation
BM Oval Series
(Refer to Table 2-1 for strainer size), ( See Figures 2-5 and 2-6).
4. Valves should be installed to facilit ate removal of the flowmeter and
strainer , (See Figures 2-4 and 2-5).
5. Install the flowmeter on the discharge side of a pump whenever
possible.
6. Before installing the flowmeter, wash and clean the inside of the pipeline
with compressed air or steam. This is particularly important on new
pipelines.
7. Remove the protective covering from the flowmeter end connectors
before installation.
8. When making connection to the flowmeter make certain that no foreign
materials enter flowmeter body .
9. Ensure that the meter is installed so that the flow of the liquid is in the
direction of the arrows embossed on the meter body .
10. Refer to Figures 2-2, 2-3 or 2-4 for electrical connections.
1. After the flowmeter has been installed, slowly allow the liquid to flow in
bypass section of a horizontal installation or the main line of a vertical
installation. This will clear the line of any foreign p articles.
2. Test the system for leaks.
3. Check the strainer for foreign material, after the first 50 gallons/200 liters
check periodically , particularly if the flow rate decreases.
NOTE: Foreign particles in the main line may cause damage to
the flowmeter .

3-1 General
The flowmeter has been completely assembled, checked and calibrated at
the factory . Therefore, no adjustment s are required for inst allation.
3-2 Flowmeter Principle of Operation (See Figure 3-1)
The Oval Flowmeter accurately measures liquid flow by using a slight
pressure differential to rotate a pair of oval gears. The meshed gears seal
the inlet from the outlet flow , developing the pressure dif ferential. When in
the position as shown in Figure 3-1A, Gear A receives torque from the
pressure difference, the torque upon Gear B cancel one another, and Gear
A drives Gear B as depicted in Figure 3-1B. When Gear A rotates to the
position as shown in Figure 3-1C, it loses torque, but Gear B obtains
torque and drives Gear A. This alternate driving action provides a smooth
rotation of almost constant torque without dead spots. Figures 3-1D, 3-1E,
3-1F, 3-1G, 3-1H, and 3-1J illustrate this principle through a complete cycle
bringing Gear A back to its original position as shown in Figure 3-1A.
During rotor rotation, the rotors trap precise quantities of liquid in the
crescent shaped gaps or measuring chambers. Total quantity of flow for
one complete cycle of the rotors is four times that of the crescent shaped
gap. Rate of flow is proportional to the rotation speed of the rotors.
Because the amount of slippage between the rotors and the measurement
chamber wall is minimal, the flowmeter is essentially unaffected by
changes in viscosity and lubricity of the liquid.

Section 3 Operation
BM Oval Series
3-3 Pulse Generator Principle of Operation (See Figure 3-1)
Pulse Generator:
When fluid passes through the meter , rotors turn. The magnets which are
located in the rotors will pass across the pulser circuit board (containing
either Reed Switches or Hall Effect sensors). A signal is received which is
then sent by the Pulse Circuit Board (PCB) to the relevant LC display or
receiving instrument.
Mechanical Display:
When fluid passes through the meter rotors turn. The gear located on top
of one of the rotors drives the mechanical registers gear train which
provides an accurate readout.
3-4 Operating Instructions
At initial operation, carefully operate in the following sequence, allowing the
flow within the flow range specified. (Refer to Figures 2-3 and 2-4).
Installation and Operation Manual
X-PD-BM-Ovals-eng
Part Number: 541B031AAG
January, 2009
1. Shut off the valve (A) on the inlet side and the valve (B) on the outlet
side and then open the bypass line valve (C) to allow the fluid in the
bypass line, thereby removing weld chips, scales and other foreign
matter left in the piping assembly.
NOTE: This is particularly important on new installations.
2. Carefully and slightly at first, open the valve (A) upstream of the meter
progressively and then, slightly at first, open the valve (B) downstream
progressively.
3. Slowly close the bypass line valve (C) and make sure that the total
counter in the receiving instrument advances in response. Maintain a
flowrate 10 to 20% of the maximum flowrate at this time, allow the flow
for more than 15 minutes and make sure that air in the piping assembly
has totally escaped.
NOTE: In applications where temperatures exceed 60°C (140°F), run the system at
least for 30 minutes in this state to ensure uniform heat distribution in the measuring
chamber.
4. Following the break-in operation (preheating), shut off the bypass line
valve (C) completely . Open the up stream valve (A) progressively until
fully open then slowly open the downstream valve (B) until the rated
flow is reached.
5. Flowrate should be regulated with the downstream valve (B) and should
be held within the rating.
6. The strainer should be inspected for condition and cleaned on a regular
basis.

3-5 Operating Precautions
Section 3 Operation
BM Oval Series
Periodic inspections should be made during flowmeter operation. The
following points should be checked and the flowmeter shut down if any
discrepancy is found.
1. When changing flowrates
In applications where the flowrate varies or where shut-off valveopening
and closure takes place in batch operation, avoid rapid changes in
flowrate across the meter. Operating the meter at flowrates in excess of
the maximum allowable flowrate will nullify the guaranteed accuracy ,
reduce the meter life and may result in faulty conditions, such as
seizure of bearings or rotor-to-measuring chamber contact.
2. Where the temperature of metered fluid changes
Avoid rapid temperature changes in the meter. Temperature changes of
the fluid in the meter should be held within 3°C, 37°F per minute.
Extra care should be used particularly when making a flow
measurement in batch operation without the provision of heat tracing
of the piping where the fluid temperature differs from atmospheric
temperature.
NOTE: If rapid temperature changes are anticipated, heat trace the piping assembly as
well as the meter.
3. Liquids of low steam pressure
4. Corrosive liquids
3-6 Precautions at Operation Shutdown
1. Valves should be closed progressively .
2. Precautions against pressure buildup on closure.
Liquids with low viscosity and low steam pressure are prone to vaporize
and their temperature and pressure should, therefore, be strictly
controlled. During operation, the temperature of bearings in the meter is
usually higher than that of the metered fluid. V apors around the
bearings can be causes of faulty conditions, including generation of
unusual noise and bearing seizure.
When you make a measurement of highly corrosive liquids, appropriate
materials should be used for tanks and piping assembly.
Heterogeneous materials originally contained in the metered fluid or
corrosive substances liquated out from tanks and pipes of inappropriate
materials may lock the rotors in the measuring chamber and lead to
costly downtime.
Rapid valve closure could, under certain piping conditions, cause a
sharp pressure rise by water hammer , or hydraulic shock, resulting in
damage to the meter.
Complete closure of valves upstream and downstream of the meter
produces a totally enclosed space between the valves. A pressure
buildup relative to a rise in atmospheric temperature could lead to
damage to the meter.

3. Liquids that readily adhere or gel.
Liquids that tend to adhere and solidify or gel at flow velocities around
zero must thoroughly be washed away from the meter interior with
running cleaning fluid before shutdown. Negligence of this precaution
could produce an immovable mass of components when the operator
attempts to resume meter operation.
NOTE: Turn pump off at end of each day.

In general, the Standard Display will always act at Operator level. The
information displayed is dependant on the SETUP-settings. Although the
refresh-rate of the display might be slow (due to power-management
functions), each flowmeter pulse will be measured. After pressing a key,
the display will be updated very fast for 30 seconds after which it will slowdown again.
For the Operator , following functions are available:
Display Rate/T ot al or Rate:
This is the main display information of the Standard Display. After selecting
other information, it will return to the main display automatically . The actual
flowrate is either displayed at the bottom line or with the 17mm digits at the
upper line. When “------------” are shown, the flowrate value is too high to be
displayed. The arrows indicate the increase/decrease of the flowrate trend.
Clear T ot al:
The value for Total can be cleared. To do so, press CLEAR,after pressing
CLEAR, the text “PUSH CLEAR” is displayed. To avoid clearing at this
stage, press a different key or wait for 10 seconds. Clearing Total DOES
NOT influence accumulated Total.
Display Accumulated Tot al:
When the SELECT -key is pressed, T otal and Accumulated Total are
displayed. Accumulated Total can never be initialised.To return to the main
display press Select or Prog/Enter , or leave for 10 seconds and the display
will return automatically .

Programming Setup-Level:
Configuration of the Standard Display is done at SETUP-level. SETUPlevel can be reached by pressing the PROG/ENTER key for 7 seconds; at
which time, both arrows will be displayed. In order to return to the operator
level, PROG will have to be pressed for three seconds. Alternatively, if no
keys are pressed for 2 minutes, the unit will exit SETUP automatically.
SETUP can be reached at all times and the S tandard Display remains full
operational.
Password: A p assword may be required to enter SETUP. Without this
password access to SETUP is denied.
SETUP is divided into several main- and sub-functions. Main functions are
selected with (u) and sub-functions with (p). Each function has a unique
number, which is displayed below the word “SETUP” at the bottom of the
display . The number is a combination of two figures. The first figure
indicates the main-function and the second figure the sub-function: For
example 12 is main-function 1 and sub function 2. Furthermore, each
function is expressed with a keyword. After selecting a sub-function, the
next main function can be selected after scrolling through all “active” subfunctions (like 1, 11, 12, 13, 14, 1, 2, 3, 31 etc.).

Programming Procedure
The Programming procedure (PROG) is applicable for programming,
selecting or deleting values on SETUP-level. The procedure is executed as
follows:
1) Enter the desired SETUP sublevel as detailed in Section 3.2.1
2) Press PROG briefly ,
3) Enter a value or make a selection with the pu keys.
4) Set the operation by pressing ENTER.
To change a value, use u to select the digits and p to increase that value. To
select a setting, both and can be used. When the new value is not valid,
the increase sign or decrease-sign will be displayed while you are
programming. When data is altered but ENTER is not pressed, then the
alteration can still be cancelled by waiting for 20 seconds or by pressing enter
for 3 seconds: the PROG-procedure will be left automatically and the former
value reinstated.
TOT AL; MEASUREMENT UNIT - SETUP LEVEL 11:
SETUP - 1 1 determines the measurement unit for TO TAL and accumulated
Total. The following units can be selected:
L - m3 - kg - lb. - GAL - USGAL - bbl - _ (no unit).
Alterations of the measurement unit will have consequences for operator and
SETUP-level values. Please note that the K-factor has to be adapted as well
(the calculation is not done automatically).
TOTAL; NUMBER OF DECIMALS DISPLAYED - SETUP LEVEL 12:
The decimal point determines for Total and accumulated Total the number of
digits following the decimal point. The following can be selected:
0000 - 1 11.1 - 22.22 - 3.333
TOTAL; K-FACTOR - SETUP LEVEL 13:
With the K-factor, the flowmeter pulse signals are converted to a quantity. The
K-factor is determined on the basis of the measurement unit and the number
of pulses generated per measurement unit by the flowmeter. Enter the
number of pulses generated by the flowmeter per selected measurement unit
(e.g per litre). The more accurate the K-factor, the more accurate the
functioning of the system will be.Example 1: Calculating the K-factor.
Let us assume that the flowmeter generates 2.4813 pulses per litre and the
selected unit is “cubic metres / m 3 “. A cubic metre consists of 1000 parts of
one litre which implies 2,481.3 pulses per m 3 . So, the K-factor is 2,481.3.
Enter for SETUP - 13: “2481300” and for SETUP - 14 - decimals K-factor “3”.
Example 2: Calculating the K-factor.
Let us assume that the flowmeter generates 6.5231 pulses per gallon and the
selected measurement unit is gallons. So, the K-Factor is 6.5231. Enter for
SETUP - 13: “6523100” and for SETUP - 14 decimals K-factor “6”.
TOTAL; NUMBER OF DECIMALS FOR K-FACTOR T OTAL - SETUP
LEVEL 14:
This function determines the number of decimals for the K-factor (SETUP13).
The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this function influences the accuracy of the K-factor
indirectly . This setting has NO influence on the displayed number of digits for
Total (SETUP 12).

Flowrate - 2
The settings for Total and flowrate are entirely separated. In this way, different
measurement units can be used like cubic meters for Total and litres for
flowrate.
FLOWRA TE; MEASUREMENT UNIT - SETUP LEVEL 21:
Setup - 21 determines the measurement unit for flowrate.
The following units can be selected:
mL - L - m 3 - mg - g - kg - ton - GAL - bbl - lb. - cf - rnd(rnd for RPM)_ (no
unit).
Alterations of the measurement unit will have consequences for operator and
SETUP-level values. Please note that the K-factor has to be adapted as well
(the calculation is not done automatically).
FLOWRA TE; TIME UNIT - SETUP LEVEL 22:
The actual flowrate can be calculated per second (SEC), minute (MIN), hour
(HR) and day (DA Y).
FLOWRA TE; NUMBER OF DECIMALS DISPLAYED - SETUP LEVEL 23:
This setting determines for Flowrate the number of digits following the
decimal point. The following can be selected:
00000 - 1 1 11.1 - 2222.22 - 3333.333
FLOWRA TE; K-FACTOR - SETUP LEVEL 24:
The K-factor is used to calculate a volumetric quantity based on the number
of pulses based on the number of pulses received within a specified time
period. This K factor is determined on the basis of the measurement unit and
the pulses generated per measurement unit by the flow meter. Enter the
number of pulses generated by the flowmeter per selected measurement unit
(e.g. per Litre). The more accurate the K-factor , the more accurate the
functioning of the system will be. For examples see SETUP 13.
FLOWRA TE; NUMBER OF DECIMALS K-FACTOR - SETUP LEVEL 25:
This function determines the number of decimals for the K-factor (SETUP
24).
The following can be selected:
0 - 1 - 2 - 3 - 4 - 5 - 6
Please note that this SETUP - influences the accuracy of the K-factor
indirectly . This setting has NO influence on the displayed number of digit s for
“flowrate” (SETUP 23).
FLOWRA TE; CALCULATION - SETUP LEVEL 26:
The flowrate is calculated by measuring the time between pulses. As several
types of flowmeters have an unequal pulse-train, it is advised to calculate the
flowrate over several pulses, for example 10 pulses; the maximum value is
255 pulses. Please understand that the calculation time for very low
frequencies (0.1-5 Hz) is influenced by this setting as well; so do not program
too many pulses! When the frequency is above 3 kHz during normal
conditions, it is advised to calculate over 50 or more pulses.
FLOWRA TE; CUT-OFF TIME - SETUP LEVEL 27:
With this setting, you determine a minimum flow requirement threshhold, if
during this time less than XX-pulses (SETUP 26) are generated, the flowrate
will be displayed as zero. Time in seconds.
Display - 3
DISPLAY; FUNCTION - SETUP LEVEL 31:
The large 17mm digits can be set to display Total or flowrate digits at
operator-level. When Total is selected, both Total and flowrate are
displayed simultaneously . When flowrate is selected, Tot al will only be
displayed after pressing select.

Power Management - 4
As the Standard Display is normally battery powered, the user will have the
concern of reliable measurement over a long period of time. The S t andard
Display has several smart power management functions to extend the
battery life time significantly . Two of these functions can be set:
POWER MANAGEMENT ; LCD UPDATE - SETUP LEVEL 41:
The calculation of the display-up-date time influences the power
consumption significantly . When the application does not require a fast
display update, we advise you to select a slow refresh-rate. Please
understand that NO information will be lost; every pulse will be counted
and the output-signals are not influenced. The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
Please note that - after a button is pressed by the operator - the display
refresh-rate will be FAST during the initial 30 seconds period. When off is
selected, the display will be switched off after 30 seconds and will be
switched on again as soon as any button has been pressed.Power
Management; Battery Mode - 42:
The unit has two modes: operational or shelf. When shelf is selected, you
can store the unit for several years; it will not count pulses, the display is
switched off but all setting are stored. In this mode, power consumption is
extremely low. Normally, the mode will be operational.

electrician has to discharge himself by touching a well-grounded object
before opening the casing.
• NEVER expose the Standard Display to strongly varying (weather)
conditions.
• When used in very cold surroundings or heavy varying temperatures, take
the necessary precautions against moisture by placing a dry sachet of silica
gel inside the display housing.
Installation
V olt age Supply Flowmeter Pick-up
Externally Powered Applications 8.30 Vdc:
When the Standard Display is externally powered, the sensor can be
powered with the same voltage by using the shared terminal 4. If the unit is
fitted with a battery as well, the output voltage of 3.2 Vdc from the battery is
blocked automatically as soon as you connect the external power-supply .
Battery Powered Applications:
A supply voltage of 3.2 Vdc is available for the signal output of the
flowmeter. This voltage MAY NOT be used to power the flowmeterselectronics, converters etc. as it is not a power supply as such! All
energy used by the flowmeters pick-up influences the battery life directly; it
is strongly advised to use a “zero power” pickup with the battery option,
such as a reed-switch. It is possible to use a low power input NPN output
signal, but the battery life time will be reduced.
T erminal Connectors
The following terminal connectors are available:

Remarks T erminal Connectors:
Terminal 1-3; Flowmeter Inputs
The pulse has to be connected to terminal 2. The screen of the signal wire
must be connected to terminal 3 (GND). The voltage supply (3.2 Vdc) to
the flowmeter should be connected to terminal 4. Please read par . 4.2. for
power supply flowmeter . The maximum input frequency is approximately 7
kHz (depending on the type of signal see Section 3.2.3.5).
Pulse-signal NPN/PNP:
The Standard Display is suit able for flowmeters which have a pulse output
that is equal or almost equal to the supply voltage (3.2 Vdc). For a reliable
detection, the pulse amplitude has to cross 1.2 Vdc once per cycle.
Transducers which generate a higher amplitude than 3.2 Vdc can be used
but the detection level is still 1.2 Vdc. Maximum voltage input is rated for
pulse amplitudes of 24 Vdc.
Figure 3-5 Pulse-Signal NPN/PNP
Reed-switch:
The Standard Display is suit able for flowmeters which have a reed-switch.
To avoid pulse bounce from the reed-switch, it is advised to select REED
LP - low-pass filter (setting 51).
Figure 3-6 Reed-Switch
Terminal 4 and 5; external power supply 8-30 Vdc:
Connect an external power-supply of maximum 30 Vdc to these terminals.
Connect the “-” to terminal 5 and the “+” to terminal 4. The output voltage
from the battery (option) is blocked automatically as soon as a higher input
voltage than 3.2 Vdc is connected: it won’t damage the battery.

Normal Operation
The quantity of liquid passing through the meter will be measured and
displayed (partial quantity counter). No additional devices are required.
A preset quantity can be transferred in automatic operation. In order to
control valves, the motor of the pump and/or other similar devices by the
meter , an amplifier according to NAMUR signals is required. The amplifier
transforms the control signal from the meter into relay signals.
For transferring foaming liquids or if shock pressures are too high;
The meter enables a measuring operation of a liquid in three steps. For
this it is necessary to use two valves.
Step 1: Both valves are open
Step 2: One valve closes (precise measuring operations starts).
Step 3: The second valve closes
1 amplifier with 2 output signals, 2 valves and a regulating valve are
required.
Leakage Quantity (Time lag of valves)
If the "OFF" signal (close) is displayed, there will be a time lag before the
valve will be closed. During this time an unknown quantity of liquid will pass
through the meter. This quantity is called leakage quantity. The leakage
quantity is measured by the meter during each measuring operation and it
is taken into account when starting the next measuring operation.
Note: The current leakage quantity always depends on the previous measuring
operation.
Factory Calibration
Factory calibration is not protected and can be changed by the user.
Calibration constant is entered prior to shipment.
Presignal Quantity:
The set presignal quantity is valid for all preset quantities.
The presignal quantity can be set between 0.0 and 9.9 Liters/Gallons.

4-8 General Maintenance for the Standard Display
• Installation, use, maintenance and de-mounting of this equipment must
be carried out by authorised technicians only .
• T ake good notice of the “Safety rules and precautionary measures” in the
front of this manual.
The Standard Display does not require special maintenance unless it is
used in low-temperature applications and/or surroundings with high
humidity (above 90% annual mean). It is the customers responsibility to
take all precautions to
dehumidify the internal atmosphere of the Standard Display in such a way
that no condensation will take place, for example by placing dry silica-gel in
the casing. Furthermore, it is required to replace or dry the silica gel time to
time as advised by the silica gel supplier.
Battery life-time:
Is influenced by several issues:
- Display update: see setup 41.
- low temperatures; the available power will be less due to battery chemistry .

Section 4 Maintenance
BM Oval Series
To extend battery life it is advised to disable unused functions.
Check periodic:
• The condition of the casing and front panel.
• The wiring of components for reliability and ageing symptoms.
• The process accuracy. As a result of wear and tear, re-calibration of the
flowmeter might be necessary . Do re-enter any subsequent K-factors
alterations.
• The indication for low-battery.
• Clean the casing with soap-water; don’t use any aggressive solvents as
these might damage the polyester coating.

cf, rnd, no unit. Time unit s: second, minute, hour, day. K-factor: 7 positions
0.000010 - 9,999,999. Number of decimals: max. three.
Problem Solving
In this appendix, several problems are included that can occur when the
Standard Display in operation.
Flowmeter does not generate pulses:
Check:
- Flowmeter, wiring and connection of terminal connectors,
see Section 4-3.
Flowmeter does generate “too many pulses”:
Check:
- Settings for Total and Flowrate: SETUP 11-14 and 21-27.
- Proper grounding of the Standard Display, see Section 4-3.
- Use screened wire for flowmeter signals and connect screen to terminal
3.
Flowrate Displays “0/zero” while there is flow (T otal is counting)
Check:
- SETUP 22 / 25: are the K-factor and time unit correct?
- SETUP 26 / 27: The unit has to count the number of pulses according to
setup 26 within the time according to setup 27.
Make sure that 27 is set to eg.10.0 seconds. The result is that the unit has
at least 10 seconds time to measure the number of pulses according to
setup 26.
The password is unknown:
If the password is not 1234, there is only one possibility left: call your
supplier .
ALARM
When the alarm flag starts to blink an internal alarm condition has
occurred. Press the “select button” several times to display the 5-digit error
code. The codes are:
0001: irrecoverable display-data error: data on the display might be
corrupted.
0002: irrecoverable data-storage error: the programming cycle might have
gone wrong: check programmed values.
0003: error 1 and error 2 occurred simultaneously
4-8
The alarm condition will almost certainly be handled internally and if all
mentioned values still appear correct, no intervention by the operator is
needed. If the alarm occurs more often or stays active for a longer time,
please contact your supplier.
