Guided Wave Radar Level Meter
₨0
Application:
Guided Wave Radar Level Meters are used to measure the level of liquid or solid materials in tanks, vessels, and silos across various industries, particularly for materials with complex surface features or conditions, low dielectric constants, and high temperatures/pressures. The technology is particularly useful for measuring the level of materials that are difficult to measure accurately with traditional level measurement technologies, and is commonly used in industries such as oil and gas, chemical, water and wastewater treatment, food and beverage, pharmaceutical, power generation, pulp and paper, mining and minerals, and agriculture.
