Level Indicators and Their Applications in Different Industries

Level sensors are used in measuring the substances that float or flow. These include slurries, liquids, powders and granular materials. There are a number of different level sensors available in the market, such as ultrasonic sensor. These gauges have importance in a number of different industries where their applications vary. The substance that requires level measuring through these indicators may be inside various containers or in their simple natural form, such as rivers, reservoirs and lakes. These sensors are, in some of the industries, of vital importance and of secondary importance in others. Here is a list of industries that these gauges are currently being used in:

• Oil Manufacturing Plants
• Water Treatment
• Paper and Pulp Production Divisions
• Petrochemical and Chemical Making & Refinery Units
• Waste Material Handling Industry
• Beverage and Food Manufacturing Factories
• Pharmaceutical Processes
• Power Generating Plants

The application of these devices in the above mentioned industries vary. There are a number of different technologies available in the market, each useful for its own specific industry. In order to make sure which level sensor you require, you will need to thoroughly research the market and check out the specification of each technology currently in use. Here are a few features of these level indicators:

• A usual sensing indicator is usually made up of the following elements: float, head, bottom bracket, measuring tape, anchors, guide wires, pipe bracket, pipe work and elbows
• The gauges usually used in measurement of boilers are magnetic sensors and bi-color level indicators
• Majority of the sensors come with illuminators which enable easy view through the dark and distance.

Here are some of the most common level indicators that are currently being used in different industries:

• Reflex level sensor level gauge manufacturers
• Tank level sensor
• Bi-color level sensor
• Transparent level sensor

Some of the most common technologies currently used in the market and considered as highly accurate and quick are:

• Ultrasonic level indicator
• Conductive level indicator
• Capacitance level indicator
• Optical Interface Level Indicator
• Magneto Resistive Level Indicator

Although all of the above mentioned sensors are considered as accurate and very helpful in a number of different industries, currently ultrasonic technology is being considered as the best. One reason for this is that these ultrasonic devices are small and handy, with the advantage of being very mobile with no moving parts. Usually, these devices come with an LCD screen and headphones, enabling both audio and visual results. They are also quick, because they used ultrasonic sound waves to detect the level. Used for highly viscous liquids, they can be used in tough conditions. Latest ultrasonic sensors come with the option of ten hour battery backup, hence no immediate power source is require. They are very useful in measurement of liquids and solids present within containers, tall or small, and come in handy in measuring liquid at its natural form too. They are moderate in price, hence preferred by the majority of industries.
