  • Fuel Sensors Explained

    A fuel level sensor is a level switch that helps identify the remaining amount of fuel in a container. Most vehicles use fuel level sensors to determine the amount of fuel remaining in a vehicle. This is an important sensor that helps many people know when to fill up their vehicles to avoid disaster along the road. Some level switches manufacturers focus exclusively on fuel sensors, but others make a variety of switches, including fuel sensors. A fuel sensor is a fascinating piece of equipment that uses a few basic...

  • Industrial Uses for a Tank Level Indicator

    A tank level indicator or level switch is a kind of sensor that identifies the level of a material inside a container or other object, such as to determine the depth of molten metal inside a mold. These sensors are necessary in many industrial applications to help identify the amount of material the factory has on hand and to help guide the correct amount of liquid through an industrial process. Three main types of level switches, thermal, optical, and vibrating, use different methods to achieve similar results. You can find...

Industry Information

Tank Level Indicator

Tank level indicators are a type of level switch that is specifically utilized within tanks, which are large vessels used to hold gases, liquids or free-flowing solids. Usually metallic, tanks can be a fairly broad category including 30 gallon and 55 gallon drums as well as most other types of large containers such as hoppers or bins.

Tank level indicators are fairly versatile types of level switches and can be used in diverse applications and industries, including petroleum, for level control of oil and gas in refineries; industrial manufacturing, for measurement of the levels of various processing media; chemical processing, for preventative level control of potentially hazardous materials; marine, used in the measurement of marine vessel fluid levels; and residential, for a variety of level indicating applications. Tank level indicators can be used not only in above ground tanks, such as overhead tanks or grounded tanks, but they can also be used for level control in underground tanks as well. Due to the diversity of the capabilities of tank level indicators, additional industries that utilize them include defense contracting, commercial, private sector aircraft manufacturing, agriculture and wastewater treatment.


Tank level indicators function mainly to measure the level of various materials based on the principle of differential pressure. This means that the level indicator is able to determine the level of the material due to the difference between the two pressures (the pressure at the bottom of the tank compared to the atmospheric pressure) being equal to the height of the material when it is multiplied by the specific gravity of the material. As a result, as long as the gravity of the material (or the density) remains the same, then the tank level indicator will be able to accurately measure the level of the material. When level measurement is based upon this principle, it is also commonly referred to as hydrostatic tank gauging (HTG). Floating level indicators are often a popular form of tank level indicators, and continuous level floats are one of the most accurate ways of measurement control in tanks. A continuous level float functions by means a sensors (which can range anywhere from two to 25 ft in length) is inserted at the top of the tank through either a flanged, welded or screwed connection. The accuracy of level measurement using this type of device is approximately up to .02 in. and as a result is used in many applications requiring high precision in measurement.
