An Underground Tank Level Indicator is a device used to monitor and display the level of liquid inside an underground storage tank. These tanks are commonly used for storing liquids such as water, fuel, or chemicals. Monitoring the tank level is essential for various applications, including managing inventory, preventing overflows, and ensuring the proper functioning of equipment that relies on the stored liquid.
Float Gauges
Mechanical Float Gauges: Use a float connected to a mechanical indicator on the surface. As the liquid level changes, the float moves and displays the corresponding level on a dial or gauge.
Electronic Float Gauges: Use sensors to measure the floats position and transmit data electronically to a display unit.
Ultrasonic Level Sensors
Use sound waves to measure the distance between the sensor and the liquid surface. The time taken for ultrasonic pulses to travel determines the liquid level.
Pressure Transducers
Measure the pressure exerted by the liquid in the tank. As the liquid level changes, the pressure varies, allowing the transducer to determine the level.
Capacitance Sensors
Measure the dielectric constant between two electrodes. The capacitance changes as the liquid level changes.
Radar Level Sensors
Use radar waves to measure the distance to the liquid surface. Suitable for a wide range of liquids, often used in industrial applications.
Hydrostatic Level Sensors
Measure the pressure at the bottom of the tank, which correlates directly with the liquid height.
