Controlling the liquid level in a reactor, tank, or other vessels accurately is critical in various industrial applications. The container must be fitted with equipment that offers constant and precise level readings to ensure the profitability and safety of industrial activities.

Inaccurate measurement leads to dangerously low or high levels in silos/vessels. While low levels cause damage to the equipment, high levels result in overflow and safety issues. 

Radar Level Transmitters: Industrial Applications

As a concept, RADAR (Radio Detection and Ranging) is still evolving in industrial ‘level measuring’ applications. RADAR detects things within its range by achieving a reflection of electromagnetic waves sent by the instrument, calculating the precise time delay of reflection, and translating the reading into the level measurement.

Because of their adaptability and excellent safety, even when subjected to extreme pressure and temperature, radar-level transmitters are recommended for continuously monitoring solids such as stones, granules, fly ash, flakes, and powders.

Accurate radar-level transmitters are employed in essential engineering situations. These transmitters or level sensors have the following industrial uses:

  • Mining

Radar Level transmitters are used in the mining industry to verify the depth or length of mines, as well as the level of the ore’s surface. Depending on the air composition, even ultrasonic radar technology attachment may be employed.

  • Boilers

Due to extremely high water and stream temperatures, measuring fluid levels in boilers is particularly challenging. Guided wave radar level sensors are employed in such instances. Since they are contactless & top-mounted, these guided probes are not affected by high temperatures. As a result, they are employed as fuel or fluid level indicators in boiler technology.

  • Aeronautics

In the automotive industry, gasoline levels are frequently measured with contact type indicators. On the other hand, a fuel storage system is a little more complicated in aviation. As a result, radar level transmitters are employed.

  • Paper and Pulp

These level transmitters are used in the paper and pulp industries to measure the level of slurry, water, and storage tanks. Because guided probes may be utilized in chemical environments, they are an excellent choice for the paper and pulp industries.

  • Bore Digging

Level transmitters are exposed to mud, slurry, and undersurface gases throughout the bore digging operation. Therefore, such instances use contactless radar level indicators to check surface levels.

Radar Level Transmitters: Why Should You Switch?

The following are the advantages of utilising a General Radar Level Transmitter over alternative level measurement technologies:

  1. Accurate Level Measurement up to 30 meters.
  2. Suitable for both solid and liquid materials.
  3. Ability to Remote Monitor in hazardous applications such as Oil & Gas, Chemicals, Pains & Coatings to sterilised environments such as Pharmaceutical and Food & Beverage industries.
  4. Even in rapidly changing levels, accurate and dependable level measurement with a high signal-to-noise ratio is possible.
  5. Because of the limited beam angle, the angle of repose is unaffected.
  6. Suitable for dusty environments and changing silo process conditions.
  7. Non-contact, with no moving parts, requires less maintenance or calibration.
  8. Top-mounted, simple installation and retrofit
  9. HART 7 o/p is simple to set up.
  10. Built-in surface profile settings avoid misleading readings caused by tank impediments.
