Flow Alarms For Glass VA
FLOSCAN INFRA-RED
FLOW ALARM SYSTEMS
FEATURES
Floscan sensors use an infra-red beam across the
glass flowtube of a Variable Area (VA) flowmeter.
Passage of the float between the sensor arms is
detected, and logic within the electronics determines
whether the float is above or below the sensor
position. Electronics inside the sensor module gives
an open collector transistor output, suitable for
external logic circuits.
Suitable for all gas flows, and liquid flows where the
float is visible, the sensor is clipped to the back of the
flowmeter frame, typically on a Platon NG/NGX Series
(normal 100mm scale) or LG/LGX series (miniature
30mm scale) VA meter.
•
High or Low flow alarm
•
Intelligent: Knows whether float above or
below sensor
•
Adjustable over full range of flowtube
•
Suitable for normal (NG/NGX) or miniature
(LG/LGX) flowmeters
•
DC output direct to standard logic circuits
•
Optional mains interface relay module
Movement up and down the frame allows the sensor
to provide a flow alarm at any point on the tube scale,
as required. The sensor can also be supplied on
Platon GU or SGUV style flowmeters.
The optional mains interface and relay module is
used to provide the DC power needed to drive the
sensor electronics, plus a SPCO 8 Amp mains relay
output. This relay acts as a slave to the transistor
output from the sensor module. Each Floscan relay
module has two output relays, and can be used to
monitor two separate alarm sensors.

Platon GU or SGUV style housings.
2. Flow Fluid
GIR sensors are supplied set up for the flowtube
size specified and either liquid or gas as the
flowing medium. The sensors are not normally
interchangeable between different sized
flowtubes.
3. Flow Scales
PRINCIPLE OF OPERATION
The Floscan sensor module positions an infra-red
detector beam accurately side to side across the
flowtube, at a pre-set level. The beam is transmitted
through the flowmeter cover and glass tube walls,
but is broken by the presence of the float. Two IR
sensitive detectors, one above the other, monitor the
passage of the float shadow: direction of float travel
is determined by the order in which the detectors
emerge from the shadow. This allows the sensor to
remember whether the float is above or below the
sensor position.
For size 1 and 2 flowtubes, the flow scale artwork
serial number (eg CA 141002) must be issue C or
later (first digit). Otherwise the scale marks may
interfere with the infra-red beam. For size 3
flowtubes, GIR sensors will work correctly on all
previously supplied scale artworks.
Consult the sales office and specify flowtube and
alarm sensor module together.
Because the NGX/NG/LGX/LG series frames are
compact units, the Floscan module is designed to be
mounted externally. Alignment is maintained by
connecting the two transmitter/receiver lobes
together around the back of the flowmeter frame,
where the whole unit clips into the extrusion groves.
For panel mounted flowmeters, this means the frame
must be spaced forwards from the panel by approx
5mm – spacers are provided.

OPTION – RELAY MODULE
The Floscan alarm optional mains power and slave
relay output module is a DIN rail/surface mounted
unit that provides DC power for one or two Floscan
sensors.
Each sensor output drives a relay in the module,
allowing external signalling via volt free contacts.
OUTPUT LOGIC:
For normal installation of
sensor, with cable exit
downwards, the output
transistor conducts for flow
rate above the set points.
START-UP LOGIC:
On power-up, the sensor has
no information as to whether
the float is above or below the
sensor. The output state is
therefore indeterminate, and
can represent high or low
flow. Once the float has
passed the sensor for the first
time, the memory logic is
triggered and the output
validated.
The two Floscan sensors can be high or low flow
alarms (dictated by the sensor orientation), on the
same flowmeter tube, or on separate flowmeters.
“Energised relay normal” conditions are displayed by
LED indicators.

When used in hazardous areas the GIR sensor should
be used with a 12Vdc supply, protected by 15 volt
100 ohm shunt diode safety barriers as - per RMRC
drawing 2-W142.
Because the GIR module requires 8V & 25mA for
correct operation, the barrier chosen must have an
end to end resistance of below 16ohms. (A suitable
barrier is the MTL767, with 155 ohm resistance).
The Platon relay module 58384 can be used to
provide a control room interface, on the safe side of
zener shunt diode safety barrier.

Floscan Alarm Type GIR
INFRA-RED FLOW ALARM SENSOR FOR
GLASS TUBE VA FLOWMETERS
1. Remove from packaging and check there is no
physical damage.
INTRODUCTION
The Floscan flow alarm sensor type GIR is an infra red
sensor module which monitors the passage of a
variable area flowmeter float through the sensor,
giving an electrical flow alarm output. One or two
sensors can be installed on a Platon Flowtube,
typically on a NG or LG series frame, held in place by
a spring clip located in the extrusion profile at the
back of the frame. GIR units can also be supplied
fitted in GU housings.
The sensor monitors the float movement to
remember whether the float is above or below the
sensor location - the electronics can only give a
reliable output after the first detection of this float
movement following power up: it loses the memory
on power down.
The sensor is external to the flowmeter cover on NG
and LG series frames, and requires that the back of
the frame is spaced from any panel by approximately
5mm. This is achieved by fitting the threaded spacers
(provided) onto the frame mounting studs.
Once fitted, the sensor can be slid up and down to
the required position on the flowtube. The normal
output is for a low flow alarm, where the cable exits
downwards. For a high flow alarm, the sensor can be
rotated through 180o with the cable exiting upwards.
Note that in this orientation the IP44 rating of the
unit will be reduced.

INSPECTION
2. Check that the following components are
enclosed:
2 x M5 threaded spacers
1 x Spring clip
1 x Sensor module
3. Check that the GIR part number identifies that it
has been set up for use on the tube size and fluid
to be used. Part numbering is as follows:
GIR 1 G
Tube size
1 = Glass Tube size 1
2 = Glass Tube size 2
3 = Glass Tube size 3
Fluid
G = Gas
L = Liquid
4. Note that GIR modules should only be used with
the glass tube supplied with the order. Older
glass tubes may have scale markings which
interfere with the infra-red transmission paths
(see Maintenance and Fault Finding section).

SENSOR INTERFACE
High Flow Alarm
Normal Low Flow Alarm
If it is required that the conducting transistor state
should occur at low flows, and that high flow
conditions should give an open circuit/no current
alarm, the GIR sensor module can be inverted on the
flowmeter frame. In this new orientation, the cable
will exit from the top face of the sensor module. Note
that in this orientation the IP44 rating of the unit will
be reduced.
The sensor is powered by a d.c. voltage (12/24V
nominal) and provides an open collector transistor
output capable of switching up to 50mA from a d.c.
supply (maximum 30V).
This output is conducting (i.e. a short circuit) for flows
higher than the set point, when the cable exits from
the base of the GIR sensor once it is mounted on the
flowtube. This is typically a low flow alarm, since low
flows give a non-conducting or open circuit output.
Interface Module (refer to OMM 1043)
When used with the Floscan alarm mains interface
module (58384) the conducting transistor output
state described above will energise the Floscan alarm
relay and light the front panel green LED. This is
therefore a failsafe low flow alarm, since power or
cable failure will cause the relay to revert to the
“alarm” state.

INSTALLATION
Orientation
Decide whether to mount the sensor in its normal
orientation, or reversed (see Sensor Interface section)
for the required output signal.
Panel Mounting
The flowmeter frame can be mounted on a vertical
panel if required, with the alarm sensor still fitted and
adjustable. To achieve this, it will be necessary to
space the flowmeter frame from the panel face by at
least 5mm: spacers are provided to fit to the
mounting studs. It will be necessary to fit the sensor
to the flowmeter frame before installing the
flowmeter against the panel. The maximum panel
thickness is reduced compared to the normal NG/LG
flowmeter, because of the spacing away from the
surface. Typically, the maximum panel thickness
possible with an alarm is 4mm.
4. If it is necessary to release the sensor, the “ears”
have to be forced back over these edges. This is
easier to achieve from the bottom edge of the
sensor (the edge where the cable exits) - lifting
this edge first.
5. The flowmeter can be returned to the vertical and
the sensor moved along the extrusion to the
required switch point. The nominal switch point
is located on the centre line of the sensor lobes.
This will give the correct low flow alarm switch
point.
The high flow alarm switch point occurs when the
bottom of the float is at the centre line of the
alarm sensor lobes. The sensor therefore needs to
be positioned with its centre line below the
required set point, by a distance corresponding to
the float length.
ELECTRICAL CONNECTIONS
(Refer to Figure 4)
Installation
RED WIRE (+V)
The sensor has been tested and adjusted to perform
best with the spring retaining clip mounted on the
opposite side of the flowmeter frame to the cable
exit from the sensor. It is easiest to install the spring
clip and sensor with the flowmeter face down, in a
horizontal plane. The spring clip and sensor are fitted
separately - they are not glued together in any way.
1. Place the spring clip inside the back of the
flowmeter frame, with the two smallest (angled)
projections located in the groove in the extrusion
(see Figure 2).
This is the d.c. power supply to the sensor circuit.
Connect to a d.c. supply between 8V and 26V
(positive with respect to the common terminal).
Nominal current drawn is 25mA.
WHITE WIRE (O/P)
This is the “output” or “signal” connection.
It is from an “open collector’ type output.
2. Place the sensor module, with the sensor lobes
downwards to the front of the flowmeter, over the
spring clip.
3. By tipping the flowmeter to make the spring clip
stay in the extrusion groove, the sensor central
block can be located behind the flat part of the
spring clip. Gentle pressure will then need to be
applied on the centre back of the sensor to press
the “ears” on the moulding past the outer lip of
the back of the flowmeter frame. The sensor will
then be held in place.
The source transistor can be used to switch up to
50mA from up to a 30V d.c. positive supply with
respect to the common terminal.
BLACK WIRE (Common)
This is the common return line for the power
supply and the output signal.
This would typically be referred to as “0 Volts”.
CABLE SCREEN
This should be connected to earth to provide the
shielding required for EMC protection.

OUTPUT PROTECTION
Fault Finding
Ex factory Protection
1. Check the sensor is correctly fitted and that the
flowtube has the scale towards the front of the
meter.
The load connected to the output cable from a
suitable d.c. supply must be sufficient to limit the
current drawn to below 50mA. Currents exceeding
50mA through the transistor will cause damage - the
transistor will fail and the warranty will be
invalidated.
Load Calculation
The external circuit must be configured as per Figure
5.
Minimum load, R = V/50mA
For a typical power rail of 24V, this calculation
shows that the load resistance, R should be 480 Ω
minimum.
MAINTENANCE & FAULT FINDING
Maintenance
2. Clean the flowmeter cover.
3. Check that the glass flow tube has not been
replaced with an older spare. Older GTF tubes
size 1 & 2 had scale markings which could
interfere with the GIR sensor: suitable new tubes
have scale codes starting with letter C, such as
CA141002. Codes starting B or 1 are not suitable.
4. Check that the GIR part number corresponds to
the float and fluid in use - this determines the
attenuator label type which is fitted on the GIR
receiver face. Ensure that the label is undamaged
and stuck in place.
5. Remove any bright source of light (which might
have an infra-red component) which could
saturate the receiver amplifiers. For example, 75
Watt filament bulbs must not be closer than 1m
to the flowmeter. A light shield (42532) can be
purchased to help with this but it will obscure
the scale at the alarm set point.
Regular maintenance can be described as:
1. Check that the sides of the flowmeter
polycarbonate cover are clean and scratch free
(inside & outside).
6. Check the external load in the output circuit.
Shorting of this load would damage the output
transistor.
7. Check the power supply connections.
2. Check that the glass flowtube is clean (inside &
outside) and positioned with the scale markings
at the front of the meter.
3. Check that the GIR sensor is properly clipped to
the flowmeter frame, to switch at the correct flow
rate, and that the internal faces of the
sensor are clean. If fitted, the attenuation label
should be stuck in place over the receiver face.
4. Only clean with a cloth dampened with water so
as to avoid electrostatic risk.
8. Check the output cable for visible damage or
kinking, which could have broken the
conductors.
9. Simulate float movement past the sensor using a
strip of paper or card, between the sensor and
flowmeter cover.
10. No repair is possible on the sensor electronics, so
a faulty unit can only be replaced completely.
5. There are no user serviceable parts.

HAZARDOUS AREA INSTALLATION
SPECIAL CONDITIONS FOR SAFE USE
The GIR sensor is approved intrinsically safe to EEx ia
IIC T4, a copy of the EC Type Examination certificate
is attached, Sira 03ATEX2401X.
The certificate number has an ‘X’ suffix, which
indicates that special conditions of installation and
use apply. Those installing or inspecting this
equipment must have access to the contents of the
certificate.
When used in a hazardous area, the GIR sensor
should be used with a 12V d.c. supply, protected by a
15V 100Ω shunt diode safety barrier as per Figure 6.
Because the GIR module requires 8V and 25mA for
correct operation, the barrier chosen must have end
to end resistance below 160Ω. A suitable barrier is
the MTL 767, with 155Ω resistance.
The following special condition of certification
applies:
Parts of the enclosure are non-conducting and
may generate an ignition-capable level of
electrostatic charge under certain extreme
conditions. The user should ensure that the
equipment is not installed or used in a location
where it may be subjected to external conditions
(such as high-pressure steam) which might cause
a build-up of electrostatic charge on nonconducting surfaces. Additionally, cleaning of the
equipment should be done only with a cloth
dampened with water.
The Floscan mains relay module (Platon part 58384),
can still be used to provide a control room interface,
on the safe side of the zener barrier.
Install the equipment following Figure 6 and the
associated notes.

INSTALLATION
a) Remove from the packaging and check that
the unit is undamaged.
b) Mount the unit as required. This can be
carried out using standard 35mm DIN rail (DIN
EN 50022-35) or by screw mounting.
c) Electrical connections shall be made using
maximum conductor size of 2.5mm2. Two
connections may be made to each terminal.
Refer to examples for sensor connection.
Mains power connections shall be within the
ranges 20 to 256V a.c, 50/60 Hz or 24 to 370V
d.c. These shall be made to the L and N
terminals. The E terminal must be connected
to Earth.
d) Once the cable connections have been made,
the terminals should be covered with the
supplied protective covers, to achieve IP20
protection. Note: This unit is designed for
mounting inside a larger enclosure. High
voltage connections should not be exposed
unless isolated.
e) The output relays are rated to 250V/8A. The
conditions shown on the unit are stated for deenergised modes, ie power down or open
circuit sensor (alarm state). When used with
the GIR flow sensor, in normal usage this
corresponds to low flow conditions.
f) The nominal input power required by this unit
is 5 watts.

OPERATION
Upon power up, the “set up” lights will illuminate.
These are designed for use with Platon GIR
Floscan Alarm sensors (see OMM1042). When
illuminated, this shows that there is no information
about whether the float is above or below the
sensor, so the alarm relay output state may be
invalid. After the float passes the sensor for the
first time, the memory logic is valid and the “set
up” light will extinguish. The “set up” LED can be
ignored for other applications.

The Platon Vampire d.c. powered flow transmitter (see OMM1033) can be powered from the Floscan relay module, and the alarm
outputs used to drive the relays. Note that current sensing for the flow analogue output must be in the 24V line.
ELECTRICAL CHARACTERISTICS
a) S1 and S2 are internally connected to 12V via 10KΩ resistors.
b) The maximum output currents for the 12V and 24V supplies are 120mA and 25mA respectively.
MAINTENANCE
This unit should not normally require any attention, but if any problems occur, check the following:
a) Isolate the power supply and then check that all connections are made correctly and that the terminal screws
are tightened. The power On LED (amber) should be lit when mains power is connected.
b) Use a voltmeter to check the output voltage supplies, taking care not to make contact with any high voltage
connections.
c) Disconnect S1 and S2 and simulate the input signals by connecting/disconnecting them directly to 0V. Relays
are energised and alarm status (green) LED’s are lit when the S1/S2 terminals are shorted to 0V.
d) The mains fuse can be located, once power is disconnected and the unit is isolated, by sliding the unit from
the housing by about 30mm. It is a 20mm T1.6A 250V rated fuse, positioned below the Live “L” terminal.
