Reflex Level Gauge with Bridle for GWR Level Transmitter
Level indicators are devices used in the measurement of level of fluids at various industrial applications. These devices are used to determine the level of liquid in tanks, drums. pressure vessels etc..
Types of Level Indicators
There are many level indicators to suit the needs of different applications. Normally, fluids are used in many forms in highly commercial industries. Without proper devices it will be very difficult to find the quantity and level of fluid stored. Also, in certain situations where the nature of fluid is dangerous or the place in which the liquid is stored is of such a nature that it is manually impossible to find the level, then the level indicators are of utmost importance.
How to Choose the Right Level Indicators
Depending on the type of application, the right level indicator should be selected. For example, in the process industry, tubular level indicators are used for better visual liquid level indication. If it is for non-contact type level measurement, then radar type indicators or ultrasonic type indicators are to be used.
This is a special type of application where a Magnetic level indicator application was ruled out because of the application constraint, our end user wanted a level measurement that suited their industry. Shridhan Automation came up with the application that would measure and control the liquids and give them a better visual liquid level indicator. Since Magnetic Level indicator was not applicable, Reflex gauge and an external chamber was adopted.
Working Principle of Reflex Glass Level Gauges
Reflex glass level gauges working principle is based on the light refraction and reflection laws. Reflex level gauges are designed to detect the difference in refractive indices of vapour and liquid and level detection and can be used in a number of process applications. Reflex gauges, also referred to as prismatic level gauges, offer a well-defined image of water levels. This reduces risks of distortions or reading areas. Because of this, a reflex level gauge can be installed in a tilt-view or vertical position to produce even greater accuracy in readings along with a much better degree of reliability, this is highly beneficial for many industries.
Applications of Reflex Level Gauges
Reflex level gauges may be applied in numerous applications to include feed water heaters, DE aerators, boiler drums, and other types of tanks.
For a reflex level gauge, within the recess of a liquid chamber and behind a single piece of glass, is the liquid column that clamps down onto the gauge body. This glass is flat on the outside and on the inside has a series of prism grooves that face the vapour and liquid space. Based on whether light enters the vapour or liquid space, it is reflected or absorbed, respectively.
Once light encounters a groove’s surface within the vapour space it reflects to the surface of the grooves on the opposite side, followed by reflecting completely back to the observation direction. During the liquid phase, light is absorbed, which creates one display for the area that is covered by liquid and another display for the area located above the liquid.
Using the prism glass, a reflex level gauge accurately measures liquid inside the vessel. When light hits the glass where there is no liquid, the prism reflects the light directly out of the gauge. Known as the "dry" area, a silver colour is displayed while the "wet" part is displayed in black. The contrasting colours create a clear delineation line that makes it easy to view the measurement.
The external chamber is a self-contained cage designed for use with our top mounting level transmitters or switches. Quality construction and a wide selection of configurations make this cage an ideal means of utilizing the power of our many technologies without mounting directly into the process vessel.
Level gauges provide a number of benefits that are industry-specific. A manufacturer like Shridhan that has specialized expertise in Manufacturing level gauges you have full assurance of enjoying optimal performance and reliability.
We understand each and every application and their advantageous to our end-users, making our products precise.

Magnetic level indicator
Customer was facing a problem of space constraint, hence there was no scope of dual chamber application which measures and control the condensate liquid level. It was important for the end user to measure and control the condensate liquid level at their plant in order to attain a quality and consistency in their production process.
Some oils are light, can be used almost immediately and are therefore very valuable. Other oils are heavy and must undergo additional refining processes before they can be used. One of the lightest and most valuable crude oils is condensate which is used to produce products like petrol, jet fuel, diesel and heating fuel. Depending on the temperature, condensate can take on various aggregate states - from liquid to gas.
SHRIDHAN, by using the above-mentioned process principle, provided the customer with a customized design in combination of MAGNETIC LEVEL INDICATOR WITH GWR Level Transmitter. It is a redundant design that suited the restricted space of the end-user
Technology Overview and Advantages
The magnetic level indicator working principle is widely used in level instrumentation. The interaction between float magnets inside the chamber and magnetic flags outside the chamber provide virtually maintenance-free, continuous level information. This type of level indicator doesn’t require power, making it ideal for a variety of applications across industries.
Magnetic level indicators are commonly low-cost in comparison with other level technologies and can provide visual indication of level from a distance. MLI devices are popular in applications measuring high-temperature, high-pressure, and corrosive liquids. When the application is challenging, magnetic level transmitters provide consistent, accurate measurements
Key advantage of guided wave radar level measurement is that no compensation is necessary for changes in density, dielectric or conductivity of the fluid. Further, changes in pressure, temperature and most vapour phase conditions have no impact on measurement accuracy; GWR is unaffected by high turbulence or vibrations; and build-up has practically no effect, meaning no need for re-calibration.
The advantage of having Magnetic level indicator with GWR level transmitter is
- Redundant Level Technology
- Increased Plant and Personnel Safety
- Single Process Connection for Two Independent Devices
The GWR transmitter obtains an independent reading of the liquid level, providing an accurate output even in the case of a float failure. Also, the GWR level transmitter will read the true level of the fluid, even if the density of the product varies.
Shridhan team were successful in installing Magnetic level Indicator with GWR that helped end-user to measure and control Condensate level of liquid, to meet their quality standards. The result is true level-measurement redundancy in a single-chamber design. Shridhan always strived for meeting organisational goals with meeting their customer requirements, and have gained an competitive edge over the product by manufacturing a unique design to fit in the space and the needs of the end-user.
Broad Flapper Design Visual Indicators
Since 2016, Shridhan Group has released the new “BROAD” visual indicators for all our magnetic level indicator products. It is a wide-flapper design that greatly improves visibility over any of the other mechanically-based visual indication products available.
Features of Visual Indicators
- 40MM - BROAD Flapper
- 60 METER - viewing distance
- 140° ANGLE - Stainless-steel housing which allows for an unmatched view
- High quality embedded vertical magnets are used in the flappers
- High quality, rigid metallic flappers
- UP TO 450°C - Yield less pivot resistance and can withstand higher temperatures
Benefits of Broad Flapper Visual Indicators
A viewing distance of up to 60 meter is achieved due to the greatly increased area of the indication surface.
The inherent benefits of Broad flapper visual indicators continue to make Magnetic Level Indicators an attractive replacement for existing sight glass technology.
These flappers incorporate a mechanism to prevent accidental flipping due to vibration or other motions. Each flapper is also limited to a half-turn of travel, thereby eliminating over-flipping that is common in competitor’s indicator designs.
Our flappers are constructed of metal, unlike plastic alternates. This is needed for indicators that are expected to withstand years of operation in tough industrial settings and extreme environmental conditions.
Compared to plastic flappers, metal flappers are of higher quality and are more reliable due to smooth metal-to-metal contacts that yield less pivot resistance and can withstand higher temperatures up to 450° C.
