Level indicator

Level indicators are used for indication of the level. The structure of the level indicator  is such that it is connected to the side of the tank in the form of a sub-tube and the liquid level in this measuring tube goes up and down at the same level as the fluid inside the desired fluid tank.
In this measuring tube, there is a float that moves along the path of the measuring tube along with the liquid level, and the magnetic level indicator based on the float displays the value on the screen. It is always suspended at the highest level of the liquid.
The level gauge indicator or magnetic level gauge is made with high quality to be highly resistant to corrosion, the most common uses of the level indicator are in open and closed tanks, tanks with multi-phase fluids, pressure tanks, and tanks containing liquid and steam. In addition, it is widely used in measuring the level of water tanks, tanks containing chemicals, fuel tanks, acid tanks and containing corrosive substances, hot water and steam boilers, pressure tanks, etc. in various industries.
Indeed, Level indicators are used for continuous indication of the level.

Types of indicator levels

  • Magnetic indicator level
  • Reflex or reflective indicator level
  • Transparent indicator level

Selection guide for level indicator

The measurement of fluids and gases in tanks and systems has always been one of the most important challenges in small and large industries, such as petrochemical, food and pharmaceutical industries, where the importance of measurement is very important due to the difference in the process and the installation operator is sensitive to it and any change should be brought back to the balance and prevent damage to the materials and system and reduce many accidents and waste of expenses.

The level indicators are designed in such a way that allows continuous measurement of the liquid level in the tank. Level indicators are usually installed laterally on open tanks or under pressure or on top of tanks. By using level indicators, users can know the exact amount of fluid when using the network, to avoid emptying or overflowing of fluid tanks and equipments.

One of the features and advantages of using the level indicator is that its easy to use and has simple design, as well as its corrosion resistance and high tolerance against unusually high and low temperatures.

Other things that can be mentioned are the mechanical nature of this tool. There is no need for electrical power, physically, the structure of the level indicator is such that it can withstand high and low pressures and also has very little failure and breakage. In addition to these items, we can point to access and the possibility of sampling the contents inside the tank for the operator.

In addition to all these items, the magnetic indicator level can be used to show the range between two fluids with different densities, such as oil and water. Another point, if you need to see the surface of the tank and the indicator in the dark, you can use lighted indicators or use fluorescent colors that shine in front of the light.
In general, as mentioned earlier, the level indicator is designed and built to determine the size and amount of chemical fluid and gas in tanks. All are important features that should be considered. The level indicator brings high flexibility to the operator. There are very important points when choosing an indicator, which should be considered based on the environmental conditions and the material, then the appropriate choice should be made, so that it is necessary to pay attention to these parameters.

Level indicator applications

Level indicators can be used in many different industries, such as:
– oil and gas

– petrochemical

– power plants

– food and beverages

– health industries

– water and sewage

– air conditioning and installations,

– house uses

and etc. Wherever there is a tank or a boiler or any device that contains a liquid fluid, a level indicator will also be needed.
