Safety Integrity Level-2

1. FLOAT OPERATED LEVEL TRANSMITTERS Level Transmitters are simple and reliable sensor for continuous level indication and control of any liquid, chemically compatible with the (sensor) material, unaffected by electrical conductivity, temperature, pressure or viscosity. The float is designed for variety of liquids and its unique self cleaning construction is well suited for even sticky or dirty environments with no float hang-ups.

FEATURES

• Continuous ‘Float Type’ Analog Sensor, resistive to most liquids• Pre calibrated at factory - No Field Calibration required• 4-20 mA, 2 wire processed output signal• High Resolution & Repeatability• Liquid level or liquid / liquid interface detection• Multiple alarm relays adjustable option• Customized lengths up to 4 meters• Intrinsically safe option available• RS-232, RS-485 compatible• Two variants of Float operated level transmitters are available 1. FLX-Reed chain level transmitters 2. MLX-Magnetostrictive level transmitters

2.1 CONSTRUCTION & OPERATIONIt consists of a float & guide stem assembly in non-magnetic material to achieve undisturbed flux. A chain of closely spaced glass encapsulated reed switches & resistors are placed inside the guide tube. During rise and fall of liquid level, the float moves & actuates a series of reed switches in the chain, through a magnet system within it and develops a proportional resistance. The operation is similar to a sliding resistance potentiometer. The sensed resistance is fed to the transmitter located in the enclosure for conversion to a signal of 4-20 mA.

FLOAT LEVEL TRANSMITTER WITH FERRULE

Ferrule type is used in applications where in the Measuring Range is not fixed or if the vessel / tank dimensions are not clearly known. Ferrule enables us to adjust the measuring range to the desired level (±300mm)

FLOAT LEVEL TRANSMITTER INSTALLED IN A CHAMBER

Wherever it is not possible or desirable to install Float Level Transmitter directly onto the vessel, switches can be installed in an External Chamber. This arrangement gives smooth level control irrespective of turbulence in the process vessel and prevents accidental damages to the switch during shutdown or maintanance of the vessel. Chambers are used in applications which require isolations of process, High Pressure / High Temperature applications, Corrosive applications, Onshore / Offshore installations.Main function of these chambers are :1. Level Measurement 2. Interface Measurement between two liquids.

FEATURES :• Available for Low Pressure and High Pressure applications.• Wide range of material of construction to suit different environmental conditions. • Wide range of end connection types / sizes to choose from.• A variety of chamber mounting arranagements provided to suit existing nozzles.

3. MLX SERIES - MAGNETOSTRICTIVE LEVEL TRANSMITTER

This high-precision and robust level transmitter is designed to provide continuous gauging of liquid media levels in tanks. The measuring principle used by the magnetic float level transmitter exploits the physical effect of magnetostriction and is largely unaffected by temperature. Magnetostriction is particularly ideal where level measurements are required to be extremely accurate, e.g. in the Petrochemical / Oil , Gas industry. The level sensor outputs measuring signals in the range of 4 to 20 mA. Available in lengths 200 to 4,000 mm, it is compatible with a variety of tank dimensions.

3.1 SPECIAL FEATURES

• 0.1mm or1mm resolution• Insertion length maximum15m• Rigid or flexible guide tube• Plastic coated version for chemicals• 4-20mA and HART output• Graphical display• 99-point linearization table • Measurement optimalisation Volume measurement• Ex version• SIL2 & IEC Certified

3.2 APPLICATIONS

• Sensor for continuous level measurement of liquids in bypass level indicators. • Chemical, petrochemical, off shore industries• Shipbuilding, machine building• Power generating equipment, power plants• Pharmaceutical, food, water treatment, environmental engineering industries

3.3 OPERATING PRINCIPLE

Inside the probe tube there is a rigid wire made of magnetostrictive material. The sensor circuitry emits pulses of current through the wire, generating a circular magnetic field. The level transmitter is a magnet, which is integrated into the float. Its magnetic field magnetizes the wire axially. Since the two magnetic fields are superimposed, around the float magnet a torsion wave is generated which runs in both directions along the wire. One wave runs directly to the probe head while the other is reflected at the bottom of the probe tube. The time is measured between emission of the current pulse and arrival of the wave at the probe head. The position of the float is determined on the basis of the transit times.

Page 20

It also comes in the following versions: The explosion-proof version of the level sensor can be installed in potentially explosive atmospheres in which electrical equipment of category 1 (zone 0) or category 1/2 (zone 0/1) are required. Operating on the digital HART protocol, the HART level sensor is able to output the position of the first, second or both floats.
