Mechanical Level Indicators

WE LFCE are manufacturer , Exporter of Float and Board Level Gauge. Which is mainly used in Storage tanks ans vessels to see the Liquid level in the tank. This type of level gauge will have direct contact the process fluids. Float and Board level gauge consists on Float, Scale Board, Pulley arrangemnts.

This instrument is an absolutely reliable and accurate system for liquid level measurement in tall overhead tanks. This type of Float & Board type Level Gauge basically work on the principle of buoyancy. The float is well connected to the counter weight along with a pointer through flexible wire ropes.

Magnetic Bi-Colour Level Gauge float moves with level in external chamber (cage) which is coupled with the tank. Indication display mechanism does not come in direct con-tact with the liquid media. Special designed cylindrical magnetic float as per density of liquid. Magnetically cou-pled follower capsule or roller or ball indicates the liquid level externally. Indicator system is consists of bi-colour 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 in-teraction between magnets in float and Ed-colour rollers causes each roller to rotate 180o. These red / white rollers are visible from long distance, giving a good visual indi-cation visibility. Models are available with side & top mounting designs.

LFIA Glass Tube Level Gauge is a simple & reliable device for direct reading in atmospheric or pressurized tank ap-plication. Mounted side of the tank through flange or threaded connection. Liquid inside the tank passes through a transparent glass tube & liquid can be viewed through the glass tube and mea-sured by a scale mounted on the gauge. Glass Tube (Borosilicate) is fully Protected by C - Cut frame.

These gauges are custom manufactured accord-ing to the C-c distance reuired.It is avail-able in single length of 2000 mm C-C Distance. We can extend the C-C length by PVC tube.

We are providing Air Vent Plug at top & drain plug at bottom for taking sample. We can also provide Inbuilt Isolation Valve on request. PP construction is made with all PP isolation valves & internals.

Reflex Level Gauge are used for measuring the level in the vessel. These can be used for maximum pressure of Upto150kg/cm² and a Maximum temperature of 400 deg C. construconal features include 2.5 Meter single piece construcon with mulple glasses between process Connecon. A pair of auto shut off ball check valves in material ofConstrucon carbon steel or stainless steel and polypropylene as oponal.

The principal of reflex level gauges is based on the difference in the refracve Indices of liquid & vapour. The liquid column is contained within the recess Of liquid chamber behind the sight glass which is clamped to the gauge body. The Sight glass has prismac right angled grooves on the side facing the liquid And vapour space light raise entering from right outside the gauge are either Absorbed or reflected depending upon whether they enter the liquid or vapour Space. When the ray of light encounters the surface of one of the grooves in vapour Space, it is reflected to the opposite space appears as silvery white. When the light Ray encounters the surface of grooves in the liquid space, it is totally absorbed Thereby the liquid behind the glass appear black. 

This type of float & Board type level gauge/indicator basically works on the principle of buoyancy. The float is well connected to the counterweight along with a pointer through flexible wire ropes. The pointer slides along the guide against a graduated scale to indicate corresponding levels inside the tank.

We are renowned organizations of market for presenting the optimum quality range of Float & Board Level Indicator.

Suitable for overhead / underground / large storage tanks. continuous level indication without power supply.
