Magnetic Float Type Cargo Tank Monitoring System General

Working Principle

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.

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

Specification

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.

Electric Pressure Type Level Transmitter (LEVEL-3000) Tank Contents Transmitter

Connection on junction box

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.

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.

Pressure Monitoring System 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.

Computer Monitor

Electric horn with strobe light

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 RS-485

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.

Fixed Gas Detection System P & ID Program

General 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.

Indicators LCD Display - High Alarm Lamp - Low Alarm Lamp - System Failure Lamp Main/Pre Flow Failure Lamp - Sensor Fault Lamp - Standby & Main Power Supply

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 PA-FLG-P100

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.

B-TYPE (TANK RETURN)

C-TYPE (SELF-CLOSING)

Gauge Body Water space

Steam/gas space

Gauge glass Light ray

Light ray

Installation Operating principle 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.

Features No harms to the environment. Safety Guarantee.

Dial Type Float Level Gauge PDG-150 Series

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.

Displacement Type Level Switch Operating principle PM - 90-1

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.

Reed Switch Type Float Level Switch Contact Protection Requirements PR-30EXD-1

PR-30S-1N

PR-30S-2N

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.
