Guided wave radar for tank gauging system

Guided wave radar (GWR) is a technology commonly used in tank gauging systems for accurately measuring and monitoring the level of liquids, solids, or interface levels within industrial tanks or vessels. It utilizes electromagnetic waves to determine the level of the substance inside the tank.

Here’s how guided wave radar technology works in a tank gauging system:

  1. Wave Propagation: GWR systems consist of a probe or rod that extends into the tank and a signal processing unit. The probe emits high-frequency electromagnetic pulses down the probe or waveguide and into the substance being measured.
  2. Reflection and Reception: When these electromagnetic pulses encounter a change in dielectric constant (such as at the liquid level), part of the energy is reflected back towards the probe’s electronics.
  3. Time-of-Flight Measurement: The time taken for the transmitted pulse to return to the probe is measured. By calculating the time difference between transmission and reception of the signal, the GWR system can determine the level of the substance in the tank.

Advantages of guided wave radar for tank gauging systems include:

  • Accuracy: GWR technology offers high accuracy in level measurements, even in challenging conditions such as varying temperatures, pressures, or complex process conditions.
  • Reliability: It is relatively unaffected by changes in environmental factors, such as temperature variations, vapor space disturbances, or foam formation on the liquid surface.
  • Versatility: GWR systems can be used in various types of tanks or vessels, including those with agitated or turbulent surfaces, high temperatures, and corrosive substances.
  • Continuous Measurement: GWR provides continuous level monitoring, enabling real-time data collection and process control.
  • Minimal Maintenance: These systems often have robust designs, requiring minimal maintenance over time.

Proper installation, calibration, and understanding of the specific application requirements are crucial for accurate and reliable measurements using guided wave radar technology.

Servo Tank Gauge Displacer Type Level Indicator

A servo tank gauge with a displacer-type level indicator is a device used for accurate and continuous measurement of liquid levels within storage tanks, particularly in industries such as oil and gas, petrochemical, chemical processing, and other liquid storage facilities.

Here’s a breakdown of its components and how it works:

  2. Displacer-Type Level Indicator: The displacer-type level indicator is a component that directly measures liquid levels. It typically involves a displacer—an object with a specific weight and buoyancy, usually made of a material like stainless steel—that is suspended from a wire in the tank. As the liquid level changes, the buoyant force acting on the displacer causes it to move up or down. This movement is used to determine the level of the liquid.
  3. Transmitter and Controller: The transmitter interprets the signals from the displacer and converts them into usable data. It then sends this information to the controller, which processes the data and provides accurate level measurements.
  4. Display Unit: The display unit shows the measured liquid level in the tank in various units (such as inches, centimeters, or as a percentage of tank capacity) for easy monitoring by operators or control systems.

How it Works:

  • The displacer is immersed in the liquid within the tank. It floats according to the liquid level changes, supported by the buoyant force exerted on it.
  • As the displacer moves, it causes changes in the tension of the wire or cable supporting it.
  • These changes in tension are measured and converted into signals by the transmitter.
  • The controller interprets these signals and calculates the accurate liquid level inside the tank.
  • The measured level data is then displayed on the unit, providing real-time information about the tank’s contents.

Servo tank gauge systems with displacer-type level indicators offer high precision and reliability in measuring liquid levels, making them essential for industries where accurate inventory management and safety are paramount. They provide continuous monitoring, allowing operators to track inventory, prevent overfilling or underfilling, and ensure compliance with safety regulations.
