Types of Level Indicator
There are many different types of level indicator, each with its own application.
• Transparent level indicator are highly useful in chemical industries and petrochemical fertilizers. As the fluid is stored in high pressure and high temperature, the transparent level indicator is very useful to find the fluid level.
• Reflex level indicator are for applications that involve high temperature, high pressure and use of corrosive fluids. The colorless fluid used in this apparatus gives better clarity to level indication.
• Magnetic level indicators are red followers that need magnetic level indicator. Cylindrical floats and powerful magnets are used to find the level of the fluid. The float movement is followed by magnetic capsules, and thus, the level in indicated. This type of indicator has good visibility and is absolutely safe to use as it contains non-fragile metal chamber.
Some other level indicator for reference are tubular level indicator, float and board level indicator, sight flow indicator, window type sight flow indicator, manometer and bi-color indicator. Some of the level indicator are provided with various features, such as a built-in controller, continuous output measurement, and adjustable alarm switches.
Level Switches and Sensor
Level indicator 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. There are many level indicator to suit the needs of different applications. Normally, fluids are used in many forms in highly commercial industries. For example, in the process industry, tubular level indicator are used for better visual liquid level indication. If it is for non-contact type level measurement, then radar type indicator or ultrasonic type indicator are to be used.
