General Instruments Consortium Gauges Bourdon India Private Limited

General Instruments Consortium offers Side Mounted Level Switches for single level set point. This is trouble free, consistent and inexpensive solution to control Level in the tanks / vessels.

GIC offers two types of Direct Mounted Level Switches:

• Series SMLS/1000
• Series TMLS/1000

This is direct mounted type level switch. This type uses counter balance principle. It consists of Float, Float Stem with counter balance weight and switch mechanism with magnet attractor. To ensure the safety and reliability GIC offers heavy wall floats.

In this type of Level Switch Float held in horizontal position and moves upwards and downwards with rising and falling level in the tank /vessel. This movement results in a rotary motion of the attractor causes actuation of micro switch. To improve reliability it employs dual opposed magnet design which provides snap action. This type of level switch is mounted directly on the tank / vessel having horizontal nozzle as shown in figure. The tank / vessel connection must be located at the elevation where set level is to occur.

Top Mounted Direct Insert Type (Series TMLS/1000)

This is direct mounted type level switch. This provides contact changeover at a selected elevation level in the tank / vessel. Switch is mounted on top of the tank / vessel and coupled with float assembly rides on the liquid surface with rising and falling of level. The magnet attractor is connected on the isolating tube as shown in figure. As the level rises stem head of float assembly reaches up to attractor causes actuation of micro switch. To improve reliability the stem guide is located just above the float. This type of level switch is used for lengths up to 2000 mm.

General Instruments Consortium offers External Cage Type Level Switches for single level set point. This is trouble free, consistent and inexpensive solution to control Level in the tanks / vessels.

GIC offers following Series of External Cage Chamber Type Level Switches:

This type of sight flow indicator is used for viewing the process flow to assure that the flow is continuous or to note the process turbidity, colour etc

Liquid Level Gauge provides direct observation of liquid level in a tank/vessel. Rising and falling level of the liquid inside the tank / vessel can be observed through the glass assembled in the gauge.

General Instruments Consortium offers liquid level gauges to suit the process requirements. If you notify process conditions i.e. Service, Pressure and Temperature etc., General can provide optimum solution to accomplish your process requirements and economy.

• Reflex Level Gauges
• Transparent Level Gauges

Reflex Level Gauge:

In this type of level gauge the liquid level is discriminated in the form of different brightness of the light on the reflex glasses. This is based on refractive indices of liquid and gas or vapor phase. In the liquid phase light is refracted to the glass and absorbed inside the gauge whereas in vapor phase light is reflected against the glass grooves and it appears very bright. This type of gauge is mainly recommended for colourless liquid. The gouge consists of a body machined to hove an internal chamber and one or more front windows only on one side of the gauge as shown in figure. On each window a special high resistance plate reflex level glass is fitted with sealing joint and metal covers seized by 'U' Bolts and Nuts.

Transparent Level Gauge:

In this type of level gauge the liquid level is discriminated in the form of different transparency of the two media. This type of level gauge is mainly recommended for coloured liquids, steam-water and interface liquid level. The gauge consists of a body having machined to have a liquid chamber and one or more windows on both the sides of the gauge as shown in figure. On each window a transparent level glass is tightly pressed with sealing joints between the metallic covers and the body by means of Bolts and Nuts

Magnetic Level Gauges provides clear, high clarity indication of liquid level. Magnetic Level Gauges are principally designed as an alternative to glass level gauges. MLGs are now widely used in all industries as they avoid direct contact with indicator system; it eliminates need of gloss for direct level indication and prevents chemical spillage due to breakage of glass.

General Instruments Consortium offers Magnetic Level Gauges in top-bottom, top and side mounted construction with two types of indicator systems i.e. Capsule Shuttle and Bicolour Rollers. Magnetic Level Gauge is consists of three major components: Float Chamber, Float and Indicator System.

Magnetic Level Gauges operates on the principle of magnetic field coupling to provide fluid level information. Float chamber is typically constructed with non magnetic pipe having process connections that matches to the vessel connections. Float size ond weight is determined by the process fluid, pressure, temperature and the specific gravity of the process fluid. Float contains magnets to provide 360° magnetic flux field.

Magnetic Level Gauge
- Flapper

Indicator system is consists of bicolour rollers equipped with magnets mounted on rail inside the housing. As the level starts rising or falling magnetic float also travels with liquid level in non magnetic chamber. The magnetic interaction between magnets in float and bicolour rollers causes each roller to rotate 180°.


Magnetic Level Gauge
- Capsule Shuttle

Indicator system consists of capsule shuttle housed in the glass tube inside the housing. As the level starts rising or falling magnetic float also travels with liquid level in non magnetic chamber. The magnetic interaction between magnets in float and capsule shuttle causes capsule to travel along with magnetic float.

Tubular Level Gauge is the simplest form of level indication.

General Instruments Consortium offers economical and reliable level gauges for direct reading of level in tanks / vessels. Tubular Level Gauges are used to visualize the level in low or medium pressure application. Tubular Level Gauges are mounted on the side of the tank / vessel. It consists of Glass Tube, Racking Material, End Blocks and Isolation Valves, vent plug, drain valve etc.

General Instruments Consortium offers Top Mounted Displacer Operated Level Switches for single and multiple level set points:

• Series TMLS/3000

This is lop mounted type level switch provided single or multiple set points. It uses displacer that do not float on the surface of liquids. Working principle of the level switch is based on a buoyancy principle. This level switch is consists of Switch Assembly, Wire Rope with Spring Assembly and Displacer suspended on spring. Displacer having more density than the process liquid is used. Spring selection is determined by the weight of the displacer. When level rises it displacer is submerged and amount of weight equal to the weight of process liquid is displaced. This displacement relives spring tension causes the actuation of micro switch. This type of level switch is used for lengths up to 10000 mm.

Top Mounted Float Operated Level Switch (Series TMLS/4000)

This is top mounted type level switch provided single or multiple set points. It uses float that glides on the surface of liquids. This level switch is consists of Terminal Enclosure, Float Stem with Reed Switches and Float with magnets assembled inside. This type of level switch can be used for single or multiple level controls. When level rises float travels with the liquid on the float stem and when it comes in contact with the reed switches located at a predetermined length of the stem, due to magnetic force reed switch changes its contact. This type of level switch is used for lengths up to 3000 mm. It is recommended to use perforated stilwell for lengths more than 1500 mm.
