Radar Gauge For Level Measurement-Features
Compact antenna design for easy installation and maintenance; non-contact measurement ensures no wear or contamination.
Resistant to corrosion, bubbles, dust, and vapor; performance is stable under temperature and pressure changes.
High-frequency radar with short wavelength provides accurate reflection even from inclined or low-dielectric surfaces.
Narrow beam angle concentrates energy, enhancing echo detection and minimizing interference.
High signal-to-noise ratio ensures precise measurement and reliable performance for fluctuating liquid or solid levels.
Suitable for measuring both liquids and solids, including low-dielectric materials, over a wide range of tank sizes.
Radar Tank Level Gauge – Explosion Proof Connection
The intrinsic safety version (Exia IIc T6) features an aluminum die-cast housing with silicone rubber sealing to prevent sparks from circuit failures from escaping. It is suitable for continuous level measurement of flammable liquids under Exia IIc T6 conditions.
This instrument must be used with a safety barrier FBS-2, which serves as the power supply and ensures intrinsic safety. Key specifications of the barrier include:
Intrinsic safety: Exia IIC
Power supply voltage: 24V DC ± 5%
Short-circuit current: 135 mA
Operating current: 4–20 mA
Installation requirements:
All cables must be shielded; maximum length from barrier to sensor is 500 m.
Stray capacitance ≤ 0.1 μF/km, stray inductance ≤ 1 mH/km.
The instrument must be properly grounded.
Only approved associated devices may be used.
This design ensures reliable explosion-proof performance while maintaining precise radar tank level measurement under hazardous conditions.
Radar Level Gauges – Working Principle
1. Space Propagation Radar (Non-contact Radar)
This type of radar level gauge emits microwave pulses from an antenna mounted above the tank toward the liquid surface. The pulses are reflected back to the antenna, and the travel time is measured to calculate the level. Non-contact radar is ideal for applications where the medium is corrosive, abrasive, or has high temperature or pressure. It is not affected by vapor, foam, or dust, making it suitable for a wide range of liquids and slurries.
2. Process Propagation Radar (Guided-wave Radar)
Guided-wave radar (GWR) uses a probe—such as a rod, cable, or coaxial waveguide—immersed in the medium to guide microwave pulses along its length. The pulse travels down the probe, reflects off the medium surface, and returns to the transmitter. GWR is highly precise and suitable for interfaces, low-dielectric liquids, and applications with limited space or turbulent surfaces. It is less sensitive to tank shape, vapor, or foam than non-contact radar.
Application of Radar Level Measurement
Radar level gauges are high-precision, non-contact instruments ideal for continuous level measurement of a wide range of liquid media, including water, industrial wastewater, hydrochloric acid, nitric acid, sulfuric acid, acidic and alkaline solutions, cement slurry, lime slurry, and various food slurries.
These instruments are widely applied across multiple industries, such as chemical processing, petroleum, water treatment, environmental protection, building materials, food and beverage, and pharmaceuticals, providing reliable, accurate, and maintenance-free level monitoring in both harsh and standard environments.

Our team can design solutions for unique tank shapes, extreme temperatures, corrosive or abrasive media, and specialized industrial environments. OEM and ODM services also cover branding, labeling, and design modifications, ensuring each radar level sensor delivers precise, reliable performance and meets your operational and safety standards.
A radar level gauge is a non-contact level measurement device that uses microwave signals to continuously measure liquid or solid levels with high accuracy, even in extreme industrial conditions.
From a manufacturer’s perspective, radar level gauges are recommended because they:
Deliver ±1–3 mm accuracy
Are unaffected by temperature, pressure, vapor, or dust
Require minimal maintenance due to no mechanical contact
Support long service life (10–15 years) in harsh environments
They are a core solution for industries requiring stable, long-term level measurement.
Radar level gauges are widely used in oil, chemical, and pharmaceutical plants because they provide safe, reliable, and contamination-free measurement.
Key benefits by industry:
Oil & Gas: Accurate tank gauging for crude oil, fuel, and LPG under high pressure
Chemical: Resistant to corrosive media, solvents, and aggressive vapors
Pharmaceutical: Non-contact measurement meets GMP and hygiene requirements
As a manufacturer, we design radar level gauges with PTFE, stainless steel (316L) wetted parts and ATEX / IECEx certifications to meet these industry standards.
An 80 GHz radar level gauge improves accuracy by using a narrow beam angle (as low as 3°), allowing precise measurement in narrow tanks and vessels with internal structures.
Technical advantages:
Better signal focusing
Reduced false echoes
Stable readings in foam, vapor, and turbulence
This makes 80 GHz radar ideal for pharmaceutical reactors, chemical vessels, and high-density storage tanks.
