Magnetic Float Type Cargo Tank Monitoring System

General

The Tank Monitoring System, named as PATROL system is a magnetic float type tank level gaugefeaturing an all-in-one detector that measures tank level, temperature,vapor pressure, as well as issuingalarm 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 comprehensivelyutilized 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 areflexible, it can be lifted up by hand without the need to enter tanks, even in the case of cargo tanks of crudeoil 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 gaugesystem and F.O tank level gauge system.

Working Principle

Sets of reed switches are positioned along thelength of the guide pipe.As the float travels up and down the guidepipe in accordance with the level of the liquidin the tank,the flux emitted from magnets within the floatworks upon the reed switches ON or OFF. By measuring voltage across the transmittercircuit, the level of the liquid can be calculatedaccording to the changes in circuit resistance. The converted signal is sent to the control boxvia I.S. barrier in the control room or to a localindicator as the case may be.

General Operating PrincipleThe 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 insidethe 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 willbe 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 cargoloading.

Air Purge Type Tank Level & Draft Gauging System

Operating PrincipleThe operating principle is based on the measuring the hydrostatic head of the liquid by providing constantlow 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 tankbottom, An air pressure corresponding to the liquid level (considering the viscosity) will be built up in thesounding pipe. If the specific gravity of the liquid is known and a pressure in the sounding pipe is measured, it is possible tocalculate 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

Application

On one side, the diaphragm is affected by the medium in the tank which is to be measured. the pressure bywhich 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. Viaan air supply and a throttle, measuring air is applied to the pressure chamber where a pressure correspondingto 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 ofstainless steel or copper are to be used between pressure converter and indicating instrument/air supply.

Primarily for as an indirect continuous measurementof level and cubic contents respectively of liquid incontainers and tanks.Our 1:1 converter is espectaily suitable for hygienicpurposes within the food, beverage and chemicalindustries as well as for potable water tanks.

The transducer is a pressure sensitive silicon micro strain gauge sensor mounted in a glass tometal 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 willbring 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.

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 thecircuit. This AC current can be amplified and fed into electronic converter in sensor housing that detectschanges in its input current caused by rising medium. this change are converted into a corresponding currentchange. If the changes exceeds an adjustable limit value, the output current rises discontinuously to > 3.4mAThe I.S.Barrier/signal converter in alarm panel uses this information to switch isolated contacts.

GeneralThe 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 pressuremonitoring system in accordance with SOLAS II-2/59 amended in 1996, and vapour pressure monitoring system requiredunder 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 PrincipleThe transmitter measures the pressure by means of a semi-conductor sensor. Pressure changes in front of the diaphragmwill bring about a resistance change. The change in resistance is linearly proportional to the applied pressure and isamplified by an integrated electronic amplifier to give an output signal. The electrical signals from the pressure transmitterson deck are connected to zener barriers in the monitoring cabinet equipped with pressure alarm lamp, buzzer and pressureindicator in the cargo control room.

The system has four(4) sample points and only one sample is directed and monitored individually through selecting valveat the time. The sampling lines are run from the respective sample point to the panel in a hazardous area. Sampling gas ispurged to a atmosphere. Oxygen sensor is designed for monitoring content from 0 to 25 V%. Indicator in control roomactivates High O2 alarm at 8% which was preset and gives audible and visual. Flowsensor fitted on flowmeter monitorssampling gas low flow and activates alarm when flow rate is under minimum flow level.Pressure transmitter monitors the pressure in waste vapour and manifold line. Low and High pressure alarm is set at 10mbar and 120mbar respectively.


Fixed Gas Detection System

General P & ID Program

The system is designed to provide protection of the following areas : Cargo pump rooms; Cofferdams ; Pipe tunnels ; Ballasttanks 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, duringballast filling. Hence it is considered sufficient that detection takes place in the upper part of the spaces whengasconcentrations 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 fromchannel 1 to 48 and then back to channel 1 again. The time that thesystem samples on a channel can be altered for eachsample line to compensate for varyingsample line lengths.

Flame arrestors are constructed from stainless steel and designed to prevent the propagation offlames from the analyzing unit if a fire occur within the unit. Flame arrestors are provided as looseitems to avoid any damage to the unit during dispatch.

The sequential gas sample system is a multi point gas-sampling unit designed to detect and providealarms for the presence of flammable and hydrogensulphide gases within the water ballast tanks and void spaces.

The system is designed to extract a gas sample fromeach sample point via sample piping to the analysingunit where the flammable and hydrogen sulphide gascontent is measured. By using solenoid valves, the unit provides an effective way of sampling multiplelocations using only one sensor for gas detection.

The system utilises a heavy-duty sample pump toextract a sample of gas from each of the sample pointlocations. The extraction circuit incorporates a flowsensing device to annunciate a flow failure if the pumpcease to operate or sample lines become blocked.Solenoid valves are used to select each sampling linefor analysis in a sequential or pre-programmedsampling sequence. Furthermore, the system isextendable by adding additional valves, which areautomatically recognised and activated. Flame arrestors are installed on all sample linesiaccordance with class regulations.

The system can supply information to the vessels AMSsystem via a communications protocol which allows fora real time flow of information including the currentlocation being sampled and the gas concentrationlevel at this location.

Flat Type Glass Level Gauge

PA-FLG-P100 SeriesThe PANASIA Flat type level gauge is designed according to JIS standardspecifications. This type level gauge is used for marine oil tanks,excludingthose of flash point of 60 below. Flat type level gauge allow an excellentobservation of colorless liquid level through reflection of several parallelgrooved glass.

Gauge Body

Water space

Gauge glass

Light ray Light ray

Steam/gas space

Operating principleThe principle of reflex glass is based on the difference in the refractive indices of liquid and gas or in particularof water and steam.. The liquid column is contained within the recess of the centre-piece behind the gaugeglass which is clamped within the gauge body. If a ray of light encounters the surface of one of the 45slanted grooves in the gas or steam space. It is reflected to the opposite surface of the groove and from theretotally 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. Lightrays entering from outside the gauge are either absorbed or reflected depending upon whether they enter thewater 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 TypeLevel Gauge

Operating principle

The measuring pipe (chamber) is connected to the tank to form a float chamber that has the same level asthe tank. A float with a built-in magnetic floats freely on the surface of the liquid and transmits its movementin 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 arewhite on one side and red on the other, As the float passes the red/white flaps, the flaps are one after theother 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 carefullevel monitoring.

Operating principleThe PANASIA dial type float level gauge consists of float, measuring steel wire and indicating unit as maincomponents. A float accurately follows liquid level variations in the vertical direction (horizontal movement of the float is wellrestricted by guide pipe).Vertical movement of the float is transmitted throught a measuring wire to the indicating unit, in which themeasuring 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 scaledial of indicating unit.

Operating principleOperation is based upon a buoyancy principle whereby a spring is loaded with weighted displacers which areheavier 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 operateswithin 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.

Description of Model

Technical data

The reed switch type float level switches consist of amagnetic float and reed switch as main components. A float equipped with permanent magnet moves up anddown with the fluid level between two stoppers and itsmagnetic field actuates a hermetically sealed reed switchincorporated in guide pipe.The switches can be normally open, normally closed orchange-over contacts. The advantage of this principle;there is only one moving part,the float.This actuates the reed switch with its magnetic field withoutcausing any wear. The reed switch is itself totally isolated from the media.These advantages give the user safe, repeatable, accurateand high operational reliability with low maintenance over along and trouble free life.

Contact Protection RequirementsWhen switching inductive loads such as relays, solenoids and transformers, reed switch contents require protection in orderto ensure long, dependable life. when current is interruped, the inductance or electrical inertia of the load generates a largefrequency voltage, which appears across the switch contacts. If the voltage is large enough, it can break down the mediumin 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 ProtectionD.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 switchopens. 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 ahight 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. For130VAC rated devices, the following table may be used for selection.
