Magnetic level Indicator

 
It is commonly used for visual level indication of liquids, which attack glass or are harzardus, flammable, toxic aggressive, agitated, contaminated and under high temperature & pressure i.e. for services, where glass gauges are unsafe.

 

Features :

Rugged gland less constructiion to provide safety in handling toxic, flammable & highly corrosive liquid.
Suitable for glass attacking liquid, where conventional gauge glass can not be used.
Option of providing continued transmitter for remote indication & control and adjustable level switch for alarm & control.

 

Construction & Operations:

It consists of a chamber and an internal float in non-magnetic material, compatitable with the liquid. The float containing a magnetic system rides on the liquid and is couples to an external visual indicator, which comes in two options. The simpler & economical design consist of a RED magnetic follower capsule, that moves within a glass tube filled with water ( To reduce friction) and can be read against a scale. THe other system is expensive and consists of a series of bicolour flappers. White on front side and contrasting RED on the reverse. These flappers rotate correspondng to floar movemetnt, thus changing their colour from WHITE to RED as the float rises and Vice-Versa when the float falls. As such the liquid level represented by an external RED column.

Liquid Level Indicators (Float & Board Type)

Target Indicator with Guded Floats
Liquid Level indicators are used for accurate liquid level gauging of fixed roof tanks stating oil, water, simple, easy installation for "Tanks-in-service" or "Tanks-out-service" and to provide a maximum of trouble free service.

The Indicators are specially recommended for application requiring a low cost,low maintenance methods for liquid level gauging and where operations necessitable occuracy to 25 min+/-.

The indicators are float-operated with a steel target that runs vertically up and down, registering tank contents on a calibrated board that is mounted outside of the tank for quick conveninet readings.

 
 

Material Of Construction

The study design and stainless steel construction of the float is resistanr to the corrosive effects of petroleum products and assures a long dependoble use.

In addition to the float assembly, the float cable, guide wires and Indicator target guide wires are of stainless steel. The target assembly and fuittings are of stainless steel. The gauge board is constructed of aluminium and has bold, legible markings in MMs and Cms with easy-to-read numerals every MM or CM. Stainless steel gauge boards are also available on special order.The level gauge is also available in P.P. or P.V.C. construction for HCL tanks. The level gauge is also available with unguided float.

All brackets and fittings necessary for mounting and installation are included.

Liquid Sea

Liquid Sea

Where it is necessory to store slovents under slight pressures, a liquid seal can be installed shown in the line figure adjuacent. Using a liquid seal will also retain the flammable or toxic vapor loss.

Standard liquid seals are made of aluminum with 18/8 sheaves and Teflon bearing and are designed for 8 1/2" W.C. pressure or vacuum.

 

Tubular Level Gauge

 
Tubular Level Gauge    
 

Simple Low cost and reliable for direct reading of clean liquid levels at low pressure & temperature conditions.

Construction & Operation :
Gauge is fitted betweeen two end blocks through gland packings. The gauge is mounted patrellel to tank so as to form a close loop causing tank liquid to seek its level in the gauge. Gauards are provided in the form of tie-rods / c-channels around the gauge to protect it from acciendental blows. End blocks have built-in solating valve, drain valve & vent plug.

 

Features :

360 c visibility with tie-rod gauards.
Glass removal/replacemetn possible w/o dismantling of gauge.
Offset isolaing valves permit cleaning of glass gauge w/o removal.

 

Special Features (Optional)

 
Illuminator Illuminates poorly lit areas for proper visual indication.
Frost Free Prevents frost formation on outer surface of gauge glass for clear visual reading in case of liquids at low temperature.
Jacketing For heating / Cooling of process liquid to prevent its solidification.
Glass Protectors : To Provide additional protection and personel safety.
Auto Ball Check : Built additional protection and personel safety.
Auto Ball check : Built into end block for preventing liquids loss, during glass breakage.
 
 

Auto Baal Check :

Autoball chheck facility is provided to prevent "Liquid loss" from vessel during breakage of gauge glass. It consists of a capsule located within the gauge 'neck' and contains a 'ball' which freeely along its inner race between the stopper & oritice. During breakage, the pressure on "ball" from gauge side will be atmospheric, whereas higher pressue from vessel side ("optg pr + liquid column") will causes the ball to move and block the office, to minimize liquid loss.
