Sight glass liquid level gauges are a mainstay of fluid processing operations that store raw materials, intermediate, or final product in tanks and other vessels. Having a direct visual indication of fluid level at the tank enhances safety and provides the all important data point about what is happening inside the tank.

These level gauges are installed on the exterior of the tank, exposed to whatever environmental or operational hazards existing or occurring at the location. Armored level gauges are appropriately named because of their construction. They are designed to resist impact and mechanical stress, as well as a range or environmental conditions.

There are generally two versions of armored level gauges, reflex and transparent. The names refer to way in which light is handled by the gauge to reveal the liquid level.

Reflex Level Gauges are ideal for clean total level indication applications for refining, petrochemical and general use applications. The reflex prisms are molded and polished to provide a crisp black-silver bi-color indication of the fluid level. As light passes into the reflex glass, if there is fluid present, the light continues through the glass and reflects off the back of the level gauge, providing a black color for fluid level regardless of the actual color properties of the process fluid. If fluid is not present, the light is reflected off the glass back towards the user, providing a shiny silver or mirror-like appearance to indicate vapor space.

Transparent Level Gauges are selected for interface level indication, dirty service or any application that requires the use of a shield to protect the glass from corrosion. A transparent gage is also known as a “thru-vision” gauge since the gauge is constructed with two pieces of flat polished glass assembled on opposite sides of the level gauge chamber. Since the user can see straight through the gauge, it is also easy to view the fluid properties, such as color, whereas this would not be possible with a reflex gauge. The use of an illuminator is always recommended on a transparent gauge.

Selecting an armored level gauge is an exercise in preparing for known and unknown events that might disable your ability to directly read fluid level. Armored level gauges are employed extensively in chemical, petrochemical, and other industries where reliability under challenging conditions is essential. Wherever there are mechanical hazards, an armored level gauge may ultimately prove to be cheap insurance against downtime or delay.

The TC tank level gauge provides accurate level measurement of liquid contents within any form of containment tank.

The level gauge integral sensor converts hydrostatic head pressure, thereby allowing continuous readings.

The rugged 316 stainless steel construction proves ideal for use with oil, water and other compatible chemicals.

We have designed level gauges, indicators and valves with utmost care for getting the maximum economy accuracy and durability. Your level indicators and level gauge should have the same strength as your vessel to withstand the high pressures to which it is subjected and the corrosive characteristics of the fluid.

Also, your valuable process fluid should never leak out through the glass fitting. In industries, you may have to measure the levels of colorless liquids, interface of immiscible fluids, liquids with sub-zero temperatures and liquids with too much foaming.

All these requirements can be met with by our latest types of tubular level gauges, flat glass level gauges and magnetic non-contact type level indicators. We manufactures following type of Level instruments:

1. Tubular Level Gauges

2. Heavy Duty Tubular Level Indicators

3. Reflex and Transparent Level Gauges

4. Boiler Level Gauges

5. Magnetic Level Indicators

6. Float & Cord Level Indicators

7. Dip Sticks & Dip Tape

8. Knob Type Level Indicator

Several forms of level gauges exist in the industry. Depending upon the types of liquids such as water, oil, diesel etc. measured by level gauges, they can be classified into following categories:

Tank level gauges

These level sensing devices generally determine volume of liquid enclosed in the tank.

Fuel level gauges

These devices mainly provide fuel level readings in case of automobiles and other equipments consuming fuel.

Water level gauges

These level gauges are basically applied to determine the rise or fall occurring in water level.

Mechanical level gauges

This category of level gauges is mainly employed in underground storage tank applications for measuring the level of liquid.

The control magnetic level gauge is designed so that the liquid being measured is enclosed within a sealed chamber. A stainless steel, titanium or plastic float fitted with a permanent omni-directional magnet moves freely inside the chamber and actuates the magnetic wafers contained within the indicator.

As the float rises and falls on the liquid level gauge each wafer rotates 180o and so presents a contrasting colour. Those wafers above the float show white, whilst those level gauge and below show red – the indicator then presents a clearly defined and accurate level gauge of the liquid in the chamber.

This simple technology provides a clear and very effective way to read your liquid level gauge within any process vessel.

The bypass level gauge is one of the simplest and most robust method to liquid level monitoring.

Bypass level gauges are one of the simplest and most robust means of liquid level monitoring. A chamber is mounted on the side of a tank or container by two process connections. This direct connection ensures that the level in the chamber corresponds precisely to the level of the liquid in the tank or container.

Inside the bypass chamber there is a cylindrical float with built-in permanent magnets, where the concentrated magnetic field produced travels through the chamber wall to an external indicator. Along with the magnetic roller indicator, the Bypass Level Gauges can also be equipped with magnetic switches and level transmitters (magnetostrictive or reed type).

Advantages are a simple, robust, and rugged design, no direct contact with aggressive fluids by sensitive measurement and indicating instruments, and guaranteed operation of the magnetic roller indicator without requiring an auxiliary power source, even in the event of power failures. These gauges are applicable throughout industry thanks to the use of a range of corrosion-proof materials. Designs are available for pressure ranges from vacuum up to 400 bar, temperature ranges from 167°C to +400°C, and densities of 350 kg/m³.

Water tank level gauges are used to quickly tell how much water is in your storage tank at any given time. We sells two types of level gauges: electronic indicators and mechanical indicators.

Electronic Indicators

Water tank level gauges with electronic indicators are a convenient way to keep an eye on your water levels from inside your own home or office.

Electronic level gauges consist of a transmitter and a receiver. The electronic indicator inside the tank transmits a wireless signal to a receiver located in the home or office.

Level gauges with electronic indicators eliminate the need for you to go to the actual physical location of the tank to read the water level.

Mechanical Indicators

Water tank level gauges with mechanical indicators work by using a weighted float and an indicator. The indicator is connected to a counter-weight which moves down with the rising water level and lifts up the float.

Level gauges with mechanical indicators are precisely accurate, as the sliding indicator located on the outside of the tank is able to match with the water level exactly.

Unlike level gauges with electronic indicators, those with mechanical indicators will never go down on you. Since there are no electronic parts,no power source is required and certainly no batteries. That makes these gauges an appealing option over those with electronic indicators.
