How Level Indicator Machine Works

Level indicators operate by using sensor probes to indicate the level of water inside a storage container. The probes transmit signals to a control panel that triggers an alarm or indicator. The panel can be set to automatically turn the pump on or off depending on whether the tank is empty or full.

Types of Level Indicators

The different types of level indicators include:

Transparent Level Indicator

Unlike glass tube gauges, transparent gauges are fitted with two plate transparent glasses which contain the fluid. The level of the fluid is indicated by transparency differences between the two media. A water stream is indicated by upward motion towards the surface of separation. For gaseous substances, light at the back of the gauge will reflect rays at the observer. This device has a metal body designed with an inside chamber and one or more windows. Each window has a special resistant transparent glass lined with a sealed joint and a metallic plate secured by joints and nuts. The chamber is coupled with a vessel threaded and welded on both ends.

Reflex Level Indicator

The reflex level indicator uses laws of reflection and refraction. The face of the glass has prismatic grooves facing inwards towards the chamber. During use, the chamber is filled with fluid in the lower zone, and gasses are put in the upper zone. The level of the liquid is distinguished by the difference in brightness of the glass. During the nighttime, an artificial light source can be used to see the variations.

Magnetic Level Indicator

The magnetic level indicator can read the level indication in any plant or operating condition. It also provides preventative protection from leakages when dealing with chemically aggressive fluids. Each cylinder will display half of its surface externally and the indicated scale will be of one color (usually white), and a red color indicates the area taken by the gas.

Applications of Level Indicator

Level indicators are used in various applications to determine fluid levels. The following are some of the applications.

  • Gauging the levels in a drum or tank of oil or water.
  • Sewerage pump control.
  • Tower cooling water level control.
  • Steam level monitoring.
  • Early warning systems for tsunamis and sea levels.
  • Batch processing and monitoring.
  • Agricultural irrigation activities.

Advantages of Level Indicators

The advantages of level indicators include:

  • Power Saver: Automatic level indicators are basic and don’t require much energy to function.
  • Economic: Apart from consuming very little power, it’s relatively cheap to manufacture level indicators, and production does not require many materials.
  • Automatic: Level indicators can function independently with minimum manual input. Due to electronic and digital components in the device, the level indicator can function on preset commands or remote control.

Drawbacks of Level Indicators

  • The water level controls need to be changed after a while because time and continued exposure to humid conditions can wear them out.
  • The rust and deterioration take effect as oxygen in the water reacts with the metallic components of the machine, reducing its life expectancy.
  • The electronics used in level indicators are built separately and require extra encasing to avoid damage.
  • Setup and installation of level indicators is complex and requires expert technicians.

Choosing the Correct Level Indicator Supplier

To ensure you have the most productive outcome when purchasing level indicators from a level indicator supplier, it is important to compare several companies using our directory of level indicator suppliers. Each level indicator supplier has a business profile page highlighting their areas of experience and capabilities, along with a contact form to directly communicate with the supplier for more information or request a quote. Review each level indicator business website using our patented website previewer to quickly learn what each company specializes in. Then, use our simple RFQ form to contact multiple level indicator companies with the same form.
