Dual flow inputs :
The model RT12 has a dual flow input feature which can be configured for one of three
available functions of A+B, A-B or A÷B (ratio).
The dual flow inputs are referred to as “input A” and ”input B” at terminals 1 & 3.
Function A+B
Both inputs are added together and displayed as one for Rate, Resettable & Accumulative
Totals.
Displays Rate : The total of A+B flow rates displayed as one rate.
Reset Total : The total of A+B totals displayed as one total.
Accum. Total : The total of A+B accum.totals displayed as one total.
Outputs Scaled Pulse : Scaled pulse value is relative to the totalised values.
Alarms : Alarms are taken relative to the displayed rate.
Analog Output : 4~20mA output is proportional to the displayed rate.
Function A-B
Input B is subtracted from input A, the resultant is displayed as one for Rate, Resettable &
Accumulative Totals.
Displays Rate : The difference of A-B flow rates displayed as one rate
Reset Total : The difference of A-B totals displayed as one total.
Accum. Total : The difference of A-B accum.tot. displayed as one total.
Outputs Scaled Pulse : Scaled pulse value is relative to the totalised values.
Alarms : Alarms are taken relative to the displayed rate.
Analog Output : 4~20mA output is proportional to the displayed rate.
Function A÷B
Input A is divided by input B, the resultant is displayed as an instantaneous Ratio, Resettable
& Accumulative Totals are independently displayed for both A & B inputs.
Displays Rate : The resultant Ratio between A÷B flow rates
displayed as an instantaneous Ratio.
Reset Total input A : The total of input A.
Reset Total input B : The total of input B.
Accum. Total input A : The Accumulative total of input A.
Accum. Total input B : The Accumulative total of input B.
Outputs Scaled Pulse : The scaled pulse output relates to input A .
* Alarms : Alarms are taken relative to the displayed ratio.
* Analog Output : 4~20mA output is proportional to the displayed ratio.
* Note: The alarm and analog outputs for the A÷B function are set in the initial stages of
programming in relation to rate units eg: setting the analog output range to 4mA = 00.000
litres/min and 20mA = 10.000 litres/min, the analog output will be proportional to the ratio rate
display of 0.000~10.000 ( eg. 4mA @ 0.000 and 20mA @ 10.000 ).
The same set up analogy applies to the alarm settings.

2. OPERATION
2.1 Accumulative Total
Accumulative total can be reset at L2 in the program mode. The accumulative total can be
displayed momentarily or continuously through use of the front panel ACCUM TOTAL key.
Momentary display : Accumulative total is displayed only whilst the key is held pressed.
Latching display : To have the accum. total display latch when key is pressed simply
press & hold the ACCUM TOTAL key for 10 seconds, the display will then latch each time the
key is pressed. Holding the accumulative total key again for 10 seconds will revert this key
function back to a momentary action.
2.2 Resettable Total ( also see page 18 for remote reset feature )
The display toggles between Rate & Total when the RATE-TOTAL key is pressed.
Pressing the RESET key whilst displaying total will cause the total to reset to zero.
2.3 Rate display
When rate is displayed the leading three alpha characters on the left of the display “flash ”
the time base for rate eg. rate /SEC. rate /MIN. rate /HR. or rate /DAY. Decimal points float
to provide good resolution & rangeability.
The minimum input frequency for rate display is 0.3hz reducing to 0.1hz If the low frequency
cut-off is set to 0.1Hz (see below).
2.4 Low frequency cut-off
The low frequency cut-off is most commonly set to 0.0Hz (disabled) other than to:
1) To display rate for input frequencies below 0.3hz, for example setting the cut-off at 0.1Hz
the rate will continue to display for input frequencies as low as 0.1Hz (one pulse every 10
seconds), such conditions often apply to flowmeters with low resolution pulse outputs (low
frequency) or flowmeters with a high operational turndown (maximum to minimum flow rate).
2) Inhibit the integration & registration of “apparent flow” which at times may be encountered
on mobile installations where the movement of the vehicle or dead heading a pulsating pump
may cause spurious flow signals which are not attributed to actual flow.
3) Inhibit the integration & registration of flow at input frequencies below what is considered
the minimum accurate flow rate of the primary flow element (flowmeter).
Caution: If the low frequency cut-off is set to any value other than 0.0Hz then the integration
of rate and total will cease at frequencies on or below the set value (HERTZ).
2.5 Inhibit total (see wiring schematic page 18)
With the remote “inhibit total” switch closed the RT with display flow rate but at the same time
will inhibit the resettable & accumulative totalising functions.
1)
Low
flow alarm
occurs when the flow falls
below the set point, High flow alarm occurs
when the flow goes above the set point.
2) Deadband (Reset Differential), provides a
buffer zone about the alarm set point in order
to avoid alarm output “chattering ” on & off
when the flow rate is hovering about an alarm
set point.
The % deadband applies above the Low set
point and below the High set point. Deadband
is set as a percentage of each set point.
Eg: 5% deadband at a low alarm set point of
100 L/hr will cause a low alarm when the
flow drops to 100 L/hr, the alarm will not
switch off until the flow increases above
105 L/hr.

Programming 13
4.10 Presetting battery power levels
When the instrument is operated under battery power only a special “Power Mode” program
option will appear at level 13 within the programming routine. A choice of three battery power
modes enable maximisation of the battery life according to operational requirements:
Ultra Power Save: Typically selected if reading the register infrequently. The display scrolls a
Prompt “PRESS ANY KEY”, when a key is pressed display wakes up for
4 minutes then returns to sleep mode* greatly extending the battery life.
Standby : Display becomes active whenever a key is pressed or product flows
through the flowmeter. Display returns to sleep mode* after 4 minutes of
no flow input or key actions, prompt then returns to “PRESS ANY KEY”.
Continuous: Display is active at all times resulting in reduced battery life. Display
reverts from Rate to Total after 4 minutes to reduce battery draw.
* In sleep mode (and programming mode) flow is always continually totalised.
5. ADDITIONAL PROGRAM PARAMETERS ( model RT12 )
5.1 Analog Output
The loop powered 4~20mA output can be spanned anywhere within the flow meter range.
Testing the current loop is available during programming when 4mA will output at
programming level L15 and 20mA will output at level L16 (page 16).
5.2 Flow Alarms
Two flow alarm FET (transistor) outputs may be programmed for Low & High flow alarms.
5.3 Flow Alarm Deadband
Alarms are NPN/PNP link selectable. An adjustable deadband (reset differential) provides
a trip buffer zone about the set point in order to overcome alarm “chattering” when the flow
rate is fluctuating close to the alarm set point.
Deadband is entered as % of each set point value (refer to page 16 for an example).
5.4 Dual Flow Inputs (see also page 20 for a fuller description)
When externally powered the RT12 accepts inputs from two flowmeters (input A& input B),
a separate scaling factor is entered for the second flow input, the instrument is then
programmed for one of the dual input functions of A+B, A-B or A÷B (ratio).
A+B Both inputs are added and displayed as one for Rate & Totals.
A-B Input B is subtracted from input A & the difference is displayed for both Rate & Totals.
A÷B Totalises A & B separately & Rate is a function of A÷B to give instantaneous ratio.
Note : - When using A & B inputs the functions of Scaled Pulse output, Alarm set points
and the Analog output are relevant to resultant computation between A & B.
- The analog output of function A÷B can be used as an input for ratio control.

12 Programming
4. PROGRAM PARAMETERS ( models RT11 & 12 )
4.1 PIN No. Program Protection
Any user defined PIN number other than 0000 will engage the program protection feature,
failure to input the correct PIN number will deny the ability to change any of the program
parameters but will allow the user to step through and view the existing program parameters.
Only one PIN number may be set but this can be changed at any time after gaining access
through PIN entry. A second back up PIN number is installed at the factory should the
programmed PIN be lost or forgotten. ( refer bottom of page 17 for the back up PIN No. )
4.2 Resetting Accumulated Total
Resetting the accumulated total can only be done at level 2 (L2) in the program mode.
4.3 Engineering Units ( refer clause 1.4 )
Select from available Engineering units to right of the display. No eng. units denote NIL set.
4.4 K-factor (scale factor)
Enter K-factor starting with the most significant number, up to 7 whole numbers & 3 decimal
numbers can be entered. Trailing decimal numbers move into view as digits to the right are
progressively selected, any significant digits which may move from view remain functional.
4.5 Rate conversion factor
A rate conversion feature is available & is explained at level 6 in the program chart (page 14).
4.6 Rate dampening
Dampening is available to smooth out fluctuating flow input signals in order to provide a
stable rate display & analog output. Most input signal are reasonably stable and need only a
low setting value of 40 to 70 ( see response graph on page 19 ).
4.7 Low frequency cut-off This feature is explained in clause 2.4 ( page 5 ).
4.8 Pulse Outputs ( Instrument must be externally powered as per page 10 )
The pulse output is link selectable as a scaleable pulse or non-scaled repeater pulse & NPN
(current sinking) or PNP (current sourcing) style pulse capable of switching up to 1 amp.
Pulse scaling, when selected, is set as the number of litres / gallons etc. per output pulse
Eg. 0.1 litres/pulse, 10 litres/pulse, 100 gallons/pulse. Range is 0.1 - 9999.9 Eng.unit/pulse.
The pulse width (pulse duration 1:1) automatically adjusts to the output frequency defaulting
to a maximum pulse width of 300 milliseconds at frequencies below 1.66hz. To calculate
pulse width at higher frequencies use: 1000 ÷(hz x 2) = pulse width in milliseconds.
4.9 Non Linearity Correction ( NLC ) - Linearisation
Linearisation enables the instrument to correct for known inaccuracies in a flowmeter thereby
improving the overall accuracy and in many cases increasing the effective flow range
(turndown) of the flowmeter. Refer to program level L12, page 15 for setting NLC points.
NLC can be used without external power however, battery life is reduced according to usage.
Note: The RT defaults out of the program mode if no programming entries are made after 4 minutes.

3.3 Wiring connections
External DC powering
Powering via 4~20mA loop
( Negative referenced )
Powering via 4~20mA loop
( Positive referenced )
Wiring requirements : Use multi-core screened twisted pair instrument cable ( 0.25 – 0.5mm2 ) for electrical
connection between the RT and any remote flowmeter or receiving instrument. The screen needs to be earthed to the
signal ground of the receiving instrument only to protect the transmitted signal from mutual inductive interference.
Instrument cabling should not be run in a common conduit or parallel with power and high inductive load carrying
cables, power surges & power line frequencies may induce erroneous noise transients onto the signal. Run instrument
cables in a separate conduit or with other instrument cables.
Installation 11
Pulse & Alarm Outputs
Current Sinking outputs ( NPN )
Current sinking derives its name from the fact that it “sinks current from a load”. When activated the
current flows from the load into the appropriate output (7,13 & 14).
Driving a logic input The output voltage pulse is typically the internal voltage of the load.
The load would normally have an internal pull up resistor on its input as shown.
Driving a coil - - - - - - - The NPN style of output is to be used when diving a coil. The coil load is
obtained by dividing the coil voltage by coil impediance ( Ω), is expressed in amps & is not to exceed
0.1A. The coil voltage is connected across & must match the RT supply voltage & the output (7,13 & 14).
Current Sourcing outputs ( PNP )
Current sourcing gets its name from the fact that it “sources current to a load”. When activated the
current flows from the output (7,13 & 14) into the load. When wired as below the output voltage pulse
is the supply voltage of the load. The load would normally have an internal pull down resistor on its
input as shown.

1.0 OVERVIEW
The Multipulse flow meter is a precision machined positive displacement flow
meter capable of measuring a wide range of liquid flows and viscosities
irrespective of their chemical or physical properties.
Each flow meter is manufactured from 316L stainless steel, suitable for a broad
selection of chemicals. Aluminium flow meters are available for specific
applications.
A flameproof option is available on all the stainless steel and aluminium models.
The Multipulse can also be used within hazardous areas when connections are
made across the reed switch output in conjunction with an approved electrical
safety barrier.
Typical I.S. barriers include:
- MTL Model 3011 or 3012
- P & F Model KHD2-OT1-Ex1
11
4.0 MAINTENANCE
4.1 Dismantling
The Multipulse has been constructed in such a way that the flow meter
manifold need not be disturbed when servicing the flow meter in-situ.
Isolate the flow meter from its source of supply and allow any excess liquid
to drain out. Remove the cap screws located around the flow meter body and
gently lever the body off the manifold at the slots provided on either side.
Caution: Lever action needs to be even on both sides so as to avoid 'walking'
the body from side to side. This inturn could damage the ceramic partition or
piston spigot, for this reason ceramic partitions are not covered by warranty.
4.2 Inspecting
Lift the piston out of the flow meter and inspect for signs of wear or damage.
Ensure that no particles are impinged into the piston walls and remove any
foreign material inside the flow meter. Inspect the O-ring and centre bearing
for damage. Replace any suspect parts.
4.3 Re-assembling
Replace the piston and rotate it by hand to ensure freedom of movement.
Align the slot in the body with the partition plate and firmly press the body evenly
onto the manifold. A smear of lubricant on the O-Ring will assist. CAUTION, the
partition plate is rectangular on all models & must be assembled with the long
face to the centre boss of the manifold.
5.0 CLEANING IN-SITU
When a system is to be cleaned in place (CIP), sterilised or purged without
removal of the flow meter, it is advisable to provide a by-pass around the
flow meter to avoid damaging the piston unless the following recommendations
are adhered to.
1) The cleaning fluid must be compatible with the piston and O-ring materials.
2) During steam sterilising ensure the steam temperature does not exceed the
maximum operating temperature of the flow meter.
3) The velocity of the steam must be carefully restricted to ensure the velocity
of the piston does not exceed the equivalent of maximum flow rate.
The same restrictions apply when purging with air or gas.

10
3.5 Hazardous area wiring
If the flow meter has been supplied with the "explosion proof option"
Exd IIB T6, then the following points must be observed:
1) Wiring techniques are to be in accordance with the rules, regulations
and requirements applying to the territory in which the flow meter is being
installed.
The units should only be connected and set up by qualified staff. The
qualified staff must have knowledge of protection classes, regulations
and provisions for the apparatus in hazardous areas.
2) When using shielded cable do not use the shield as an electrical earthing
conductor. Be sure to isolate the shield / screen from any contact with the
flow meter. The shield / screen is to be connected to the instrument earth
only to protect the transmitted signal from mutual inductive interference.
Electrical earthing lugs are located within the terminal housing cover & on
the underside of the manifold . Use a separate earth within the cable
making sure that the earth conductor does not come in electrical contact
with the cable shield / screen.
3) Use only high temperature cable at the flow meter if the unit is being used
to measure process liquids above 85°C.
4) For Exd explosion proof versions only, the output board has been
assembled into the flow meter terminal housing using a small amount of
potting solution.
If the output board is to be replaced in an Exd version, remove the two
securing screws and then the output board (force will be needed to break
the PC board away from the potting solution). Clear away all remaining
potting solution.
To fit the new output board first fill the recesses in the bottom of the
terminal housing with a small amount of flexible potting solution
( approximately 2ml ) so that there is about 2mm depth of coverage
within the recess slots then fit new output board and allow time for potting
solution to set. Use 3M Scotch guard 2130 potting solution or similar.

3.0 ELECTRICAL CONNECTIONS
3.1 Instrument cable
Twisted pair low capacitance shielded instrument cable 7 x 0.3mm (0.5mm²)
should be used for electrical connection between the flow meter and the remote
instrumentation. The screen should be earthed at the readout instrument end
only to protect the transmitted signal from mutual inductive interference.
The cable should not be run in a common conduit or parallel with power and high
inductive load carrying cables as power surges may induce erroneous noise
transients onto the transmitted pulse signal or cause damage to the electronics.
Run the cable in separate conduit or with other low energy instrument cables.
3.2 Pulse output selection
Each flow meter has two independent pulse output signals that are linearly
proportional to volumetric flow. Pulse transmission can be up to 1000 metres
providing that wiring runs are in accordance with good wiring practices (see 3.1).
Reed switch :
A voltage free contact closure output providing a regular frequency ideally suited
for frequency to analog conversion & instantaneous flow rate indication. The
Reed Switch is also used for integrating and batching applications & is
connected into an approved intrinsically safe barrier when used in hazardous
locations. Maximum load is 24Vdc, 50mA limited by an integral 500ohm current
limiting resistor included in series with the reed switch.
Hall Effect sensor :
A high resolution, solid state, 3 wire NPN open collector requiring 5~24 Vdc
max. (20mA max.), produces a pre-shaped and amplified square wave more
suited to small volume batching applications requiring high levels of repeatability.
The square wave pulses are unevenly spaced due to the cyclic motion of the
piston but like the reed switch each pulse is representative of an equal volume.
Pulse output resolution :
Each flow meter is individually calibrated and supplied with a calibration
certificate showing the number of pulses per unit volume for the Hall sensor and
the reed switch outputs. Nominal figures are shown below.

1.3 OPERATING PRINCIPLE
The Multipulse flow meter utilises the oscillating piston principle, where the
passage of liquid causes a piston to oscillate smoothly in a circular motion
inside a round measuring chamber. Each piston cycle displaces a known
volume of liquid from the inlet port to the outlet port. Small high energy
magnets located within the piston activate the integral electronics which in
turn generate high resolution pulse outputs suitable for remote flow integration
instruments, computers and PLC's .
1) The liquid flows through inlet Ainto 2) The volume outside the piston, to
the inner area of the piston causing the right, is displaced and exits
the piston to move in the direction through the opening B. Liquid also
of the arrow. flows through the inlet Ainto the
left- hand outer area.
3) The inner area of the piston is 4) The volume within the piston
completely cut off. The liquid flowing flows through the outlet B.

the piston further.

2.0 INSTALLATION
2.1 Orientation
The flow meter can be mounted in any orientation. However, for optimum
performance and ease of inspection, it is desirable to mount the flow meter in a
horizontal section of pipe. This ensures the rotating piston is not influenced by
gravity when at rest.
2.2 Meter location
The flow meter should be fitted upstream of any flow control or cut-off valve. This
prevents free discharge from the flow meter and minimises the risk of drainage
and air entrapment which may cause erroneous readings on start up.
The Multipulse positive displacement flow meter does not require any flow
conditioning, therefore straight runs of pipe before and after the flow meter are
not necessary.
The flow meter is not to be exposed to any form of hydraulic shock or over
speeding as this could damage the internals.
2.3 By-pass Installation
It is our recommendation the flow meter be installed in a by-pass section of pipe
with isolation valves to enable the flow meter to be isolated during pipeline
purging. If a by-pass is impractical, flush the pipe work to purge out foreign
matter such as rust, welding slag and sealing compound prior to installing the
flow meter or temporarily remove the piston, partition and centre bearing to allow
free passage of the foreign matter.
The by-pass configuration should also be used if the system is exposed to
periodic steam or air purging. ( See 5.0 Cleaning In-Situ )
2.4 Strainers
It is sound practice to locate a suitably sized strainer immediately upstream of
the flow meter. Recommended strainer mesh sizes are;
Model No. Mesh size Microns
MP015 100 150
MP025 / MP040 50 250
MP050 25 500
A range of strainers are available to suit both the Multipulse PD and Turbopulse
turbine meter range.

2.5 Commissioning
Immediately after installation or after long periods of shut down, the flow meter
must be slowly purged of air. This can be achieved by allowing the liquid to flow
through the flow meter at a slowly increasing rate until the air is released.
When metering liquids with a viscosity greater than that of water, the maximum
flow rate must be reduced to a level that will produce a pressure drop across the
flow meter of no more than 280 kPa ( 2.8 bar ).
The flow meter is now ready to put into service and will accurately measure all
liquids passing through it, provided it is not operated outside its specified limits.
2.6 Reverse flow (bi-directional flow)
The flow meter is capable of accurately measuring flow in the reverse direction.
Meters fitted with the QP output option (quadrature pulse output) may be
interfaced with the Trimec Pulse Discriminator Module (PD1) to separate
forward & reverse flow output pulses for input to the appropriate totalising
registers or add and subtract counter input.
It is important to note that the Quadrature Pulse option has the same pulse
resolution (pulses/unit volume) as that of the reed switch for each size
Multipulse flowmeter.
Where reverse flow is not to be registered it is wise to install a check valve
upstream of the flow meter.
