Magnetic Float Type
Cargo Tank Monitoring System
General
The Tank Monitoring System, named as PATROL system is a magnetic float type tank level gauge
featuring an all-in-one detector that measures tank level, temperature,vapor pressure, as well as issuing
alarm when limits are exceeded.
The TANK MONITORING SYSTEM monitors these tank conditions on various display units.
Information on ballast tanks, fuel oil tanks and draft gauges, as well as cargo tanks can be comprehensively
utilized by integrated ship operation control system via a loading computer.
A key feature of the Tank Monitoring System is its ease of handling, because the sensors in the detector are
flexible, it can be lifted up by hand without the need to enter tanks, even in the case of cargo tanks of crude
oil Tanker, Product oil Tanker, chemical carrier for repair and maintenance.
Likewise, transportation and fitting of the Tank Monitoring System is also simple.
For LNG carrier, this magnetic float type tank level gauge is usually provided in W.B.T & Draft gauge
system and F.O tank level gauge system.

Working Principle
Sets of reed switches are positioned along the
length of the guide pipe.
As the float travels up and down the guide
pipe in accordance with the level of the liquid
in the tank,
the flux emitted from magnets within the float
works upon the reed switches ON or OFF.
By measuring voltage across the transmitter
circuit, the level of the liquid can be calculated
according to the changes in circuit resistance.
The converted signal is sent to the control box
via I.S. barrier in the control room or to a local
indicator as the case may be.

Magnetic Float Type
High & Overfill Alarm System
General Operating Principle
The PANASIA high level alarm sensor consists of magnetic float and reed switch built in guide pipe.
When the magnetic float moves upward with rising level, the hermetically sealed magnetic reed switch inside
the pipe will be de-activated.
This switch will be in an open-state position, which output alarms.
When the magnetic float moves down ward with falling level, the reed switch switch will be activated and will
be in a closed-state position (non alarm position).
This means a normally operated fail to safe loop.The 95% switch is normally for high alarm.
The 98% Switch is normally for high-high alarm(overfill alarm)
A test lever is provided for manually functional test to check integrity of high level alarm system before cargo
loading.

Air Purge Type
Tank Level & Draft Gauging System
Operating Principle
The operating principle is based on the measuring the hydrostatic head of the liquid by providing constant
low flow of air into a probe (called as sounding pipe) which opens at the tank bottom.
When a light quantity of air (supplied from flow regulator) is discharged through the purge mouth at the tank
bottom, An air pressure corresponding to the liquid level (considering the viscosity) will be built up in the
sounding pipe.
If the specific gravity of the liquid is known and a pressure in the sounding pipe is measured, it is possible to
calculate the distance from the pipe opening to the surface by means of the above expression.
The pressure is read on the indicator graduated scale in meters or volume or percent of full tank.

1:1 Converter
(Pneumatic Tank Level Gauge)
Operating Principle
On one side, the diaphragm is affected by the medium in the tank which is to be measured. the pressure by
which the diaphragm is affected is the hydrostatic pressure of the fluid or gaseous medium.
On the other side, the diaphragm is fastened with the pressure converter, forming so a pressure chamber. Via
an air supply and a throttle, measuring air is applied to the pressure chamber where a pressure corresponding
to the hydrostatic pressure of the medium develops. This pressure can be shown by an indicating Instrument.
the pressure on the supply of measuring air must always exceed the highest media pressure.
Excess air is blown out through the nozzle in the center of the pressure converter.
To avoid distortion, the flange must be fastened at least 4points before final welding. Connecting tubes of
stainless steel or copper are to be used between pressure converter and indicating instrument/air supply.
Application
Primarily for as an indirect continuous measurement
of level and cubic contents respectively of liquid in
containers and tanks.
Our 1:1 converter is espectaily suitable for hygienic
purposes within the food, beverage and chemical
industries as well as for potable water tanks.

Electric Pressure Type
Level Transmitter (LEVEL-3000)
Tank Contents Transmitter
This is a 2-wire 4-20 mA level transmitter consisting of a transducer and an amplifier connected via a 6-core
vented cable. The transducer is a pressure sensitive silicon micro strain gauge sensor mounted in a glass to
metal seal. The sensor is protected by an isolation diaphram, electron beam welded to the transducer housing,
with an oil filling between the sensor and the diaphragm. Pressure changes in the front of the diaphragm will
bring a resistance change in the Wheatstone bridge of the transducer.
This change in the Wheatstone bridge will be transmitted to the amplifier as a change in the electrical signal.

Water Ingress Alarm System
This system is designed to detect the presence of water in
the cargo holds and intended for usage on bulk carriers.
The system is in accordance with
SOLAS chapter XII/12
IMO Res. MSC.145(77)
IACS SC 180
Principle of Operation
Electrode type level switch is suitable for level detection in conductive liquid.
If the electrode comes into contact with the liquid, the A.C current will flow through the liquid and complete the
circuit. This AC current can be amplified and fed into electronic converter in sensor housing that detects
changes in its input current caused by rising medium. this change are converted into a corresponding current
change. If the changes exceeds an adjustable limit value, the output current rises discontinuously to > 3.4mA
The I.S.Barrier/signal converter in alarm panel uses this information to switch isolated contacts.

General
The pressure monitoring system is designed for cargo tank & manifold pressure monitoring for any number of tanks.
The vapour pressure monitoring system is intended for pressure monitoring of waste return lines.
The PANASIA pressure transmitter is carefully designed to meet a harsh marine application for the tank pressure
monitoring system in accordance with SOLAS II-2/59 amended in 1996, and vapour pressure monitoring system required
under 46CFR part 39. 20-13 of VECS.
The transmitter is a high quality and accuracy semi-conductor type especially suitabe for the low pressure to be measured.
Operating Principle
The transmitter measures the pressure by means of a semi-conductor sensor. Pressure changes in front of the diaphragm
will bring about a resistance change. The change in resistance is linearly proportional to the applied pressure and is
amplified by an integrated electronic amplifier to give an output signal. The electrical signals from the pressure transmitters
on deck are connected to zener barriers in the monitoring cabinet equipped with pressure alarm lamp, buzzer and pressure
indicator in the cargo control room.

The sequential gas sample system is a multi point
gas-sampling unit designed to detect and provide
alarms for the presence of flammable and hydrogen
sulphide gases within the water ballast tanks and
void spaces.
The system is designed to extract a gas sample from
each sample point via sample piping to the analysing
unit where the flammable and hydrogen sulphide gas
content is measured. By using solenoid valves,
the unit provides an effective way of sampling multiple
locations using only one sensor for gas detection.
The system utilises a heavy-duty sample pump to
extract a sample of gas from each of the sample point
locations. The extraction circuit incorporates a flow
sensing device to annunciate a flow failure if the pump
cease to operate or sample lines become blocked.
Solenoid valves are used to select each sampling line
for analysis in a sequential or pre-programmed
sampling sequence. Furthermore, the system is
extendable by adding additional valves, which are
automatically recognised and activated.
Flame arrestors are installed on all sample lines
iaccordance with class regulations.
The system can supply information to the vessels AMS
system via a communications protocol which allows for
a real time flow of information including the current
location being sampled and the gas concentration
level at this location.

The system is designed to provide protection of the following areas : Cargo pump rooms; Cofferdams ; Pipe tunnels ; Ballast
tanks and double bottoms ;Void spaces ; Other empty area’s adjacent to slop tanks.
Additionally, stool tanks and other empty areas adjacent to cargo tanks can be protected.
When locating fixed sampling points within ballast tanks, areas where an explosion is most likelyto occur must be assessed.
The risk of explosion is mainly related to the release of cargo vapours through the ballast vents in the top of the tank, during
ballast filling. Hence it is considered sufficient that detection takes place in the upper part of the spaces whengas
concentrations reach detectable levels.
We advise that ballast tank-sampling positions belocated at the top of the tank.
The sampling system extracts gas samples from a maximum of 48 lines and the default sample sequence is to cycle from
channel 1 to 48 and then back to channel 1 again. The time that thesystem samples on a channel can be altered for each
sample line to compensate for varyingsample line lengths.
Flame arrestors are constructed from stainless steel and designed to prevent the propagation of
flames from the analyzing unit if a fire occur within the unit. Flame arrestors are provided as loose
items to avoid any damage to the unit during dispatch.

Flat Type Glass Level Gauge
PA-FLG-P100 Series
The PANASIA Flat type level gauge is designed according to JIS standard
specifications. This type level gauge is used for marine oil tanks,excluding
those of flash point of 60 below. Flat type level gauge allow an excellent
observation of colorless liquid level through reflection of several parallel
grooved glass.
Water space
Gauge glass
Gauge Body
Light ray Light ray
Operating principle
Steam/gas space
The principle of reflex glass is based on the difference in the refractive indices of liquid and gas or in particular
of water and steam.. The liquid column is contained within the recess of the centre-piece behind the gauge
glass which is clamped within the gauge body. If a ray of light encounters the surface of one of the 45
slanted grooves in the gas or steam space. It is reflected to the opposite surface of the groove and from there
totally reflected-back into the direction of observation.
The steam or gas space therefore appears as silver-white.
The gauge glass has prismatic right angled grooves, On the side facing the water and steam spaces. Light
rays entering from outside the gauge are either absorbed or reflected depending upon whether they enter the
water or steam space.
The light ray which encounters the surface of a groove in the liquid space is almost totally absorbed.
The liquid behind the reflex glass therefore appears back.

Magnetic Float Type
Level Gauge
Operating principle
The measuring pipe (chamber) is connected to the tank to form a float chamber that has the same level as
the tank. A float with a built-in magnetic floats freely on the surface of the liquid and transmits its movement
in the pipe, without physical contact, to an externally mounted indicating strip (Indicator).
The indication strip is placed on the ou side of the pipe and consists of numerous magnetic flaps which are
white on one side and red on the other, As the float passes the red/white flaps, the flaps are one after the
other turned 180 around their own axis.
The flaps change from white to red with rising level and from red to white with falling level.
The magnetic level gauge is particular advantage wherever dangerous and toxic media calling for careful
level monitoring.

Dial Type Float Level Gauge
Operating principle
The PANASIA dial type float level gauge consists of float, measuring steel wire and indicating unit as main
components.
A float accurately follows liquid level variations in the vertical direction (horizontal movement of the float is well
restricted by guide pipe).
Vertical movement of the float is transmitted throught a measuring wire to the indicating unit, in which the
measuring wire is wound around a tape pulley kept under constant torque by constant spring.
the vertical movement is converted into rotation of the tape pulley in this way.
This rotation is transmitted through a gear system to an indicator pointer which reads the liquid level on a scale
dial of indicating unit.
Application
Generally applied to Water tank and L.O, D.O and
H.F.O.tanks.
Besides, magnetic coupling type dial float level gauge
is applicable to the liquids that emits corrosive,
inflammable or poisonous gases.

Float Type Level Switch
Operating principle
PANASIA magnetic float level switchs monitor and control liquid
levels in open or closed tank. A permanent magnet is part of a float
which rises or falls with the changing liquid level.
This magnet repells another magnet located opposite in the switch
housing. In this way it causes a snap action contact effect.
A switch unit provides on-off contacts.

Displacement Type
Level Switch
Operating principle
Operation is based upon a buoyancy principle whereby a spring is loaded with weighted displacers which are
heavier than the liquid.
Immersion of the displacers in the liquid results in a buoyancy force change, which moves the spring upward.
Since the spring moves only when the level moves on a displacer, Spring movement is always a small
fraction of the level travel between displacers. A magnetic sleeve is connected to the spring and operates
within a non-magnetic barrier tube. Spring movement causes the magnetic sleeve to attract a pivoted
magnet, actuating a switch located outside the barrier tube.
Switch set points are achieved by moving displacer modules up or down the displacer wire/rod.

Reed Switch Type
Float Level Switch
Operating principle
The reed switch type float level switches consist of a
magnetic float and reed switch as main components.
A float equipped with permanent magnet moves up and
down with the fluid level between two stoppers and its
magnetic field actuates a hermetically sealed reed switch
incorporated in guide pipe.
The switches can be normally open, normally closed or
change-over contacts.
The advantage of this principle;there is only one moving part,
the float.
This actuates the reed switch with its magnetic field without
causing any wear.
The reed switch is itself totally isolated from the media.
These advantages give the user safe, repeatable, accurate
and high operational reliability with low maintenance over a
long and trouble free life.

Contact Protection Requirements
When switching inductive loads such as relays, solenoids and transformers, reed switch contents require protection in order
to ensure long, dependable life. when current is interruped, the inductance or electrical inertia of the load generates a large
frequency voltage, which appears across the switch contacts. If the voltage is large enough, it can break down the medium
in the gap between them, making a conductive path. this phenomenon, called arcing is the spark you see.
Arcing can cause the contacts to burn, weld together or stick; thus, giving unreliable performance.
The purpose of protection circuits is to prevent arcing, by shorting this voltage through an alternate path.
Recommended Protection
D.C.
A 1N4004 diode(or equivalent) connected cathode-to-positive, as shown in Figure 1, is recommended.
The diode does not conduct when the load is energized, but conduts and shorts out the generated voltage when the switch
opens. The generated voltage always acts in series with the applied voltage.
A.C.
A resistor and capacitor, connected in parallel with the switch, as shown in Figure 2, is recommended. The capacitor is a
hight impedance to 60hertz, but is essentially a short circuit high prequencies of generated voltages.
Transient suppressors or varistors may also be used to dissipate the transient and protect the switch contacts. For
130VAC rated devices, the following table may be used for selection.
