IMPORTANT INFORMATION
Thank you for purchasing a Kobold Insertion Flowmeter. It is important that you
read this manual to gain a full understanding of the capability and operational
aspects of the equipment you are about to install.
This information is provided only to assist in the installation of the product and
does not diminish your obligation to read the manual.
1. Select a location that meets the requirements as illustrated on the guideline
sheet (please see the data sheet/order codes). An ideal installation would provide
for 25 diameters of straight pipe upstream from the meter and 10 diameters
downstream.
You will also need to know the pipe internal diameter (NB) and pipe wall thickness
for calculation of the insertion depth. (refer page 5.) Non ideal installations may
require in-situ calibration (refer to the factory for details).
2. After screwing the flowmeter in place ensure the flow alignment mark located
on the top positioning collar of the meter aligns with the flow in the pipe (refer
page 5). This ensures the paddle is correctly aligned to the flow.
Note. the meter is bi-directional so a flow direction arrow is not provided.
3. Calculate and adjust the height of the flowmeter (refer page 5).
4. Electrical Installation depends on the model you have purchased.
If the dualpulse is fitted or supplied with a receiving instrument such as a totaliser
or rate totaliser please refer to the appropriate manual and page 10 of this
manual. For pulse output meters, select the appropriate output and wire to your
receiving device. (refer pages 7 to 9).
5. Calculate the flowmeter K (scale) factor to suit the installation. For ideal
installations refer to page 11 or 12 or 13 of the flowmeter Manual. For non ideal
installations the K-factor may be calculated by performing an in-situ calibration.
Enter the appropriate K-factor into your receiving instrument.

1.2 Overview
Kobold insertion flow transducers provide a cost effective and simple means of measuring
the flow of a wide range of low viscosity liquids. Installation is quick and inexpensive for
pipe diameters ranging from 40mm to 900mm (1.5-36") and up to 2500mm (100") nominal
bore for the Hot tap capable model DOR-52.
The flowmeter has a linear measuring range of 0.3~10.0 metres/sec. (1~33 ft/sec.).
Minimum detectable flow velocity is 0.15 m/sec. (0.5 ft/sec.). When used in conjunction with
the ZOD-Z3 flow rate totaliser NLC feature the linear flow range is extended down to 0.15
m/sec. (0.5 ft/sec.) with an improved linearity.
The flowmeter is constructed from 316 L (1.4404) stainless steel enabling use in many
applications for metering water and low viscosity chemicals.
Two independent pulse outputs are standard & can directly input to a wide range of
ancillary instruments, PLC’s and computers. Both pulse outputs have a high level of
immunity to electrical interference. Options include a reed switch.
1.3 Operating principle
Flow passes through a pipe causing the rotor to spin. Magnets installed in the rotor pass by
pulse sensors within the transducer body & inturn this produces frequency outputs
proportional to flow rate.

2.0 INSTALLATION
2.1 Meter location
Choose an appropriate section of horizontal or vertical pipe as per the guidelines below.
With vertical pipe installations the media should be pumped up through the pipe past the
flow sensor so that any entrained air will pass freely.
The DOR flow sensor requires a fully developed turbulent flow profile to ensure maximum
measurement accuracy and repeatability. This can be achieved by installing the DOR in a
straight run of pipe. We recommend at least 10 but ideally 25 straight pipe diameters
upstream & at least 5 but ideally 10 pipe diameters downstream of the flowmeter. Major
obstructions such as pumps, valves or strainers will require longer straight runs before and
after the flowmeter.
10 pipe dia. minimum
25 pipe dia. prefered 5 pipe dia. min.
10 pipe dia. prefered
FLOW
Major obstructions such as
pumps,valves,reducers or strainers
to be kept well outside the straight
run pipe sections
2.2 Meter installation & orientation
Cut a 40mm diameter hole (1.6") on either the 2, 10 or 12 o’clock positions of the pipe. If
there is any likelihood of air entrainment in a horizontal pipe do not locate the flow
transducer in the 12 o’clock position.
Install a female threaded weld on fitting (threadolet) or service saddle.
Wrap the threads of the flowmeter with PTFE tape or sealing compound & screw the unit
into the installed fitting.
page 5
2.3 Height adjustment calculation
Calculate the adjustment height A for DOR-42 (or AA for the DOR-52) as follows:
A( for DOR-42 ) = 175mm ( 6.9") - ( B + C + D )
AA ( for DOR-52 ) = 420mm (16.5") - ( B + C + D )
Where :
B= Distance between the top of the pipe & the top of the hex adaptor.
C= Pipe wall thickness
D= Insertion depth ( pipe ID ÷ 8 )
Examples of insertion depth D:
For 40mm pipe ID ( D= 5.0 mm )
For 50mm pipe ID ( D= 6.25 mm )
For 100mm pipe ID ( D= 12.5 mm )
For 400mm pipe ID ( D= 50.0 mm )
Turn the height adjustment nuts (1) as required so that the distance between the top of the
hex adaptor (2) and the top of the positioning collar (3) equals your calculated distance A
(for DOR-42) or AA for model DOR-52. Retighten the height adjustment nuts (1).
2.4 Flow direction orientation
The unit is bi-directional however the paddle must be aligned with the direction of flow.
Using a 2mm hex key (Allen key), unlock the locking screw located on the positioning collar
(3) then insert the hex key (as a lever) in the body rotating hole located above the collar,
turn the body until the alignment slot is parallel with the direction of pipe. Retighten the
locking screw.

2.5 Hot tap installation
( model DOR-52 )
CAUTION : Hot tap installation
should only be performed by
qualified personal. Installation
procedures should be in accordance
with the safety rules, regulations and
requirements applying to the territory
in which the flow transducer is being
installed.
If necessary extend valve
port using a 2” nipple &
socket combination to
ensure the paddle is clear
of the ball valve.
IMPORTANT
Before removing the
DOR-52 from the
installation first
withdraw the
transducer body to
the maximum
distance allowed by
the three height
adjusting threaded
rods. This will enable
the isolating valve
to be fully closed
without damaging the
paddle.

3.3 Instrument cable installation requirements
Use twisted multi-core low capacitance shielded instrument cable (22 AWG ~ 7x 0.3
stranded) 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. Run the cable in separate conduit or with other low energy
instrument cables .
3.4 Pulse output selection ( standard outputs )
The standard flowmeter has two independent pulse output signals that are linearly
proportional to volumetric flow rate. Pulse transmission can be up to 1000 metres (3300 ft ).
An optional I.S. Reed Switch output is available (see page 7).
Voltage pulse (pulse wire) output
A self generating pulse output which produces a strong 1.5 volt voltage spike of
approximately 10 micro/second duration with no dependence on rotor speed.

Square Wave Pulse (Hall sensor) ( also applies to non-magnetic & QP Hall outputs )
An NPN open collector transistor pulse output produced by a solid state Hall Effect device.
This three wire device requires 5~24vdc and produces an NPN square wave output (20mA
max. sink), pulse width is 2~75 mSec. The Hall output requires a pull up resistor, these are
generally incorporated in most receiving instruments. For (QP) Quadrature pulse output
refer details page 9.

3.5 Quadrature outputs
DOR series flow meters supplied with the QP option produce two NPN open collector pulse
outputs from two Hall Effect sensors. The outputs are “ phase offset ” in their timing so that
external electronics are able to differentiate. These outputs may be used to assure output
signal integrity or to measure bi-directional flow.

3.6 Bi-directional flow
The DOR flow transducer is capable of accurately measuring flow in both directions without
modification. Meters fitted with the QP output option (quadrature pulse output) may be
interfaced with the Pulse Discriminator Module (PD2). The PD2 accepts the Quadrature
pulse inputs & from these will discriminate between forward & reverse flow. Two individual
& proportional pulse outputs can then be sent to appropriate totalising registers or an Z3
add and subtract flow rate totaliser.
It is important to note that the Quadrature Pulse option has the same pulse resolution
(pulses/unit volume) as a standard flowmeter for both forward & reverse outputs.

4.0 K – FACTORS ( calibration factors for meter )
The K-factor (pulses / litre, gallon etc.) will vary in relation to the bore size of the pipe in
which the flowmeter is installed.
The K-factors and formula shown are a result of factory testing using smooth bore piping
under ideal conditions. Variations to the given K-factors may occur when using rough bore
piping or inadequate flow conditioning on either side of the flow transducer (refer clause
2.1). In these instances on site calibration may be used to determine the K-factor.

4 Introduction
1.3 Overview
The ZOD-B1 is a dc powered high speed batch controller specifically designed for liquid
batching using a flowmeter with a pulse or frequency output.
ZOD-B1 is push button programmable with PIN protection and an internal battery is provided
allowing pre-programming without applying power. The large LCD provides batch quantity in
selected engineering units, batch status and has scrolling English prompts to make
programming easy.
Two independent output relays, the second with programmable start delay and pre-stop,
enable pump and valve control or 2 stage flow phasing at the start and end of each batch.
Precise batching is aided by Automatic Overrun Compensation which, when enabled,
automatically manages variations in system time lags which could otherwise lead to
discrepancies in dispensed quantity.
Safety features includes for an alarm output and automatic cessation of batching if no flow
input is detected and programmable batch limiting protects against setting an oversize batch
quantity. Scrolling messages on the LCD annunciate any alarm fault conditions.
Control features include batch count up or down, remote operational switch interface, run
inhibit interlock and batch status output. The ZOD-B1 is capable of networking with up to 9
batch controllers using one common flowmeter.
Environments
The ZOD-B1 is designed to suit harsh indoor and outdoor industrial environments & conforms
to EMC directives. The housing is weatherproof to IP66/67 (Nema 4X) standards, UV
resistant, robust glass re-enforced plastic with stainless steel screws & FKM O-ring seals.
ZOD-B1 can be mounted on a variety of flowmeters or as a stand alone instrument for wall,
surface, pipe or panel mount. Various mounting kits are available.

2. OPERATION
2.1 Batch set : Pressing the Batch set key allows the user to enter a batch value by
using the arrowed keys to select the appropriate digits and change their value. Pressing
Batch set again enters & confirms that the new batch value has been entered.
2.2 Run : Press RESET then RUN to start the batch. If there are no interruptions the
batch controller will automatically stop the batch once the batch value has been reached.
2.3 Stop : Pressing the STOP key at any time during the batch will cause the batcher to
go into a “PAUSED ” state and the output relays will be turned off. At this point the user can
resume batching by pressing the RUN key or abort the batch by pressing the RESET key.
2.4 Batch Total : The batch value is displayed in all normal operational modes.
2.5 Accumulative Total : Accumulative total can be reset in the program mode.
The accumulative total is displayed momentarily by pressing the ACCUM TOTAL key.
2.6 TNB display ( Total number of batches ) : ZOD-B1 will accumulate the total number of
individual completed batches. Reset of TNB is simultaneous with the resetting of the
Accumulative total in program mode. To view the TNB value simultaneously press & hold the
two top right hand keys ( Prog. & Accum Tot).

Relay Control Logic
Wiring requirements : Use multi-core screened twisted pair instrument cable (0.25~0.5mm2 ) for
electrical connection between the ZOD-B1 and any flowmeter or remote switch input. The screen needs to be
grounded at -0V (terminal 8), this is to protect the transmitted signal from mutual inductive interference.
Instrument cabling should not be run in a common conduit or parallel with power or high inductive load 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.

See notation on 1N4004 diode. When the solenoid valve coil is de-energized
it generates its own voltage sending a “surge spike” through the circuit.
Depending on the coil size and the number of amp turns it contains, this
generated voltage can be very high. Installing the diode will suppress this
“spike” and protect sensitive components of the electronic instrument.

4. PROGRAM PARAMETERS
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 19 for the back up PIN No. )
4.2 Resetting Accumulated Total & Total Number of Batches ( TNB )
Resetting the Accumulated Total & Total Number of Batches (TNB) is done at “RESET
ACCUMULATIVE TOTALS ” in the program mode. Both Accumulated Total & TNB are reset
if you select YES at this program level.
4.3 Engineering Units ( refer clause 1.4 )
Select from available Engineering units to right of the display. No engineering units denote
NIL set allowing the user to set up the instrument with other units of measure which are not
available on the ZOD-B1 LCD display.
4.4 K-factor ( scale factor )
Enter K-factor starting with the most significant number, up to 7 prime 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 Decimal Points
Up to three decimals points can be selected for Batch Total or Accumulative Total.
4.6 Count Direction
B1 can be programmed to count DOWN from a preset quantity or UP from zero.
Overruns in the count down mode will show with a minus sign in front of the overrun value.
4.7 Start Delay & Pre-Stop
Relay 2 can be programmed to turn on a time period after the run signal is given then turn off
again a preset number of litres, gallons etc. before the end of the batch. These operational
features provide greater control over the dynamics of the batching process through soft start
and/or soft stop or phasing of the control valves and/or pump control.
The Start Delay can be set from 0 seconds ( no delay ) to 999 seconds. The pre-stop range
is 0 (no pre-stop) to 999 units of measure ( litres or gallons etc.).
Programming 13
4.8 Automatic Overrun Compensation ( AOC )
Most batching applications will have an inherent end of batch overrun due mainly to the
response time of the process valve. Overrun can be compensated by closing the valve
slightly before the batch value is reached so that the exact batch value is achieved by the
time that the system comes to rest.
ZOD-B1 has an Automatic Overrun Compensation feature which when enabled will assess
the degree of overrun on previous batches and automatically alters the close timing of the
process valve so that the exact batch value is reached. This feature should not be enabled
on batch processes which are subject to erratic or inconsistent flow conditions.
4.9 Missing Pulse Detection
When a value other than 00 seconds is set at Time Out ( T / OUT ) in the program mode,
ZOD-B1 will monitor for loss of flowmeter input signal at all times when either of the control
relays 1 & 2 are energised. If no pulses are received within the time out period ( 0~99 sec. )
the controller will de-energise both control relays and scroll a “NO INPUT” message across
the LCD display, at the same time it will turn on the “no flow alarm” output at terminal 7, (see
page 17 for flow alarm connection detail).
At “NO INPUT ” the user must acknowledge the alarm condition by pressing the STOP key
once, the operator then has the option of continuing the batch by pressing the RUN key or
aborting the batch by pressing the RESET key which will return the controller to the original
batch set value.
4.10 Batch Limit
To avoid entering excessive batch quantities, a maximum batch limit can be set at the
program level. ZOD-B1 will not accept a batch value which exceeds the batch limit, on
rejecting an excessive batch value the controller will scroll the message “BATCH VALUE
EXCEEDS BATCH LIMIT” and default to the batch limit on entry (batch set).
4.11 Controller networking ID number
Each controller can be given a networking ID number in the range of 1~9. Allocating an ID
number other than 0 is only necessary when a number of controllers are to be networked
together for interlocking purposes ( see page 18 for Controller Networking ). Setting the ID
number to zero inhibits this function.
Note : The instrument defaults out of the program mode if no program entries are made
after 4 minutes.

16 Secondary I/O
7. SECONDARY I/O
7.1 Batch Status Output
A solid state NPN output signal is switched on at terminal 12 when a batch is started, the
signal remains on until the batch cycle is completely finished or the batch is stopped and
aborted using the STOP & RESET keys.
The output is used to notify other control equipment when ZOD-B1 is in operation or is
paused (by pressing STOP) or inhibited through an input at terminal 9 (RUN inhibit), the
signal remains on under all three conditions. The signal can also be used to inhibit (lock out)
other equipment whilst the controller is in use.
7.2 Alarm Output
An NPN/PNP selectable solid state output signal (terminal 7) is activated when the missing
pulse detection feature detects a no flow condition (refer 4.9). NPN/PNP selection is to be in
accordance with the connection options on the following page (17).
7.3 Run Inhibit Input
The RUN inhibit feature enables ZOD-B1 to interlock with other devices within the system or
process when ZOD-B1 is in use.
When a contact is made across the Run inhibit input at terminal 9, a batch cannot be started
and at the same time an “ENGAGED “ prompt will show on the LCD display. If the inhibit
contact is made whilst a batch is running the batch will be paused. When the run function is
inhibited it is still possible to enter a new batch quantity or review the accumulated totals but
it will not allow the operator to RUN or re-start the batch until the inhibit input is released.
An example of this feature in practice is where a batch should not be allowed to RUN whilst a
valve at another location is open.
Solid state output logics 17
7.4 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 ( terminals 7, 12, 13 & 14 ). NPN is the factory
default configuration for the outputs. Refer to pages 10 & 11 for wiring control outputs.
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 driving a coil. The coil load is
obtained by dividing the coil voltage by coil impediance ( Ω), is expressed in amps & is not to exceed
100mA at terminals 7 & 12 or 1A at terminals 13 & 14. The coil voltage is connected across & must
match the ZOD-B1 supply voltage & the appropriate output ( terminals 7, 12, 13 & 14 ).
7.5 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.

18 Networking
8. CONTROLLER NETWORKING
ZOD-B1 has a unique networking feature which allows up to 9 individual batch controllers to
be networked together with each being connected to one common flowmeter (see opposite).
Typical applications are where one liquid is being dispensed to a number of individual outlets
or a number of different liquids are to be batched via one common flowmeter. In either
application each batch controller is wired to the same flowmeter but controls its own process
control valve.
Networking takes place when any one controller is started, at this point the flowmeter input
(count) is restricted to the controller in use, all other controllers will not count and their start
function will be inhibited and an “ENGAGED” will scroll across the LCD display showing the
ID number of the controller in use.
Batch entries can be made whilst individual batch controllers are inhibited (locked out) but
they cannot be started until the controller in operation has completed its batch cycle.
For the network feature to work the network DIP switches must be set as shown & each
batch controller MUST be programmed with an individual ID number other than 0 (zero).
