Nexisense LF-001 Series Radar Level Meter for Liquid Tanks: Non-Contact Level Measurement Solution for System Integration and Engineering Projects
In the implementation of industrial automation projects and long-term operation and maintenance, the accuracy of level measurement for liquid and solid powder storage tanks is directly related to material balance, production safety and project acceptance efficiency. For system integrators, engineering companies and project contractors, traditional contact instruments often face problems of adhesion, blockage and frequent maintenance under high-viscosity, easy-crystallization, strong corrosion or high-temperature and high-pressure conditions, while non-contact radar measurement has become the preferred technical path to reduce operation and maintenance costs and ensure data continuity.
The Nexisense LF-001 series radar level meter specially designed for liquid tanks adopts microwave pulse echo technology and is designed for industrial storage tank level monitoring. Through high-frequency microwave signals and dedicated demodulation algorithms, it achieves precise distance measurement to the surface of liquids and solid powders, providing reliable and continuous level data support for automation control systems. This series of products balances versatility and engineering adaptability and can be widely used in petrochemical, food and beverage, pharmaceutical, environmental water treatment, energy storage and transportation and other fields.
Working Principle and Core Technical Features
The LF-001 series radar level meter emits an extremely narrow microwave pulse through the antenna. The pulse propagates at the speed of light. When it encounters the surface of the measured medium, part of the energy is reflected back and received by the same antenna. The time interval between the transmitted pulse and the received pulse is proportional to the distance from the antenna to the surface of the medium. Thanks to the 500MHz-1.8GHz operating frequency and dedicated demodulation technology, the instrument can accurately identify nanosecond-level time difference values and complete level calculation through a microprocessor.
Technical features include:
Non-contact measurement, completely avoiding direct contact between the medium and the sensor, suitable for viscous, crystalline, foamy and strongly corrosive media.
Single-rod antenna design, compact structure, low installation space requirements, suitable for storage tanks with limited top space.
Measurement is not affected by medium density, temperature, pressure and steam interference, suitable for complex process conditions.
Fast response speed, supporting real-time continuous output, meeting the needs of DCS/SCADA systems for dynamic level monitoring.
Industry Application Scenarios
The LF-001 series performs excellently in various industrial storage tank projects:
Petrochemical Storage Tanks: Level monitoring of crude oil, finished oil, chemical raw materials and acid-base solution storage tanks, supporting deployment in explosion-proof areas.
Food and Beverage Storage: Level control of syrup, fruit juice, edible oil and raw material tanks, meeting hygienic installation requirements.
Pharmaceutical and Fine Chemical: High-purity reagents, sterile solutions and organic solvent storage tanks, ensuring GMP validation data reliability.
Environmental Water Treatment: Level collection for sewage treatment regulating tanks, chemical storage tanks and clean water tanks, connected to SCADA for remote monitoring.
Energy Infrastructure Projects: Level management of diesel, lubricating oil, coolant and liquefied gas storage tanks, providing accurate inventory data for energy management systems.
In the above scenarios, the instrument can be used as an industrial IoT edge node to directly upload level data to the cloud platform, supporting predictive maintenance and material balance optimization.

For engineering procurement and system integration needs, the LF-001 series provides clear parameter configurations:
Measurement Range: 0～30m, covering the height of most industrial storage tanks.
Measurement Accuracy: ±10mm, meeting conventional process control and auxiliary metering requirements.
Antenna Type: Single-rod antenna (stainless steel or PTFE optional).
Process Temperature: -40℃～+250℃.
Process Pressure: -0.1～4.0MPa.
Explosion-proof Grade: Exia II C T6 Ga / ExdII C T6 Gb.

Real Project Application Cases
In a storage tank area renovation project of a petrochemical enterprise, the integrator selected 50 units of LF-001 series instruments to replace the original float level meters. The instruments were connected to the existing PLC system via RS485 bus to achieve stable measurement of 30m high storage tanks. The level data fluctuation was controlled within ±8mm, and the annual maintenance cost decreased by about 60%.
In another raw material storage tank project of a pharmaceutical factory, the LF-001 explosion-proof instrument was deployed in volatile organic solvent storage tanks. The data was synchronously uploaded to the central control room, meeting the national hazardous chemical safety management specification requirements, and the project passed acceptance smoothly.
FAQ
Q1: Can the LF-001 series work stably in storage tanks with high steam content?
A: Yes. The instrument adopts microwave pulse technology and has strong suppression ability against steam and condensation. It is recommended to enable the steam compensation function during configuration and reserve appropriate purge interfaces during installation.
Q2: How to ensure the measurement effect of the instrument in high-viscosity or easy-crystallization media?
A: The single-rod antenna surface is smooth, and the influence of medium adhesion is small. In engineering, PTFE coated antennas can be selected, and the echo threshold and gain parameters can be appropriately adjusted during debugging.
Q3: How to prevent address conflicts and communication interference when networking multiple instruments via Modbus?
A: The instrument supports free address allocation. It is recommended that each bus segment does not exceed 32 units, and terminal matching resistors should be added. Relays can be used for segmented networking if necessary.
Q4: Does it support converting level height to volume output instead of only height value?
A: Supported. By inputting tank shape (cylinder, conical bottom, spherical tank, etc.) through upper computer or instrument internal parameters, automatic volume conversion can be realized and directly output through Modbus registers.
Q5: How to ensure explosion-proof certification and EMC compatibility in engineering projects?
A: The product has passed Exia II C T6 Ga and ExdII C T6 Gb certification and provides complete EMC test reports. On-site installation must strictly follow grounding specifications.
Q6: What is the minimum order quantity and delivery arrangement for bulk purchase?
A: Standard models support minimum order of 30 units, and customized models depend on complexity. Framework agreement customers can lock delivery time and reserve inventory.
Q7: How to choose between four-wire and two-wire power supply in engineering selection?
A: Two-wire is suitable for long-distance transmission and loop-powered scenarios; four-wire is suitable for control cabinet installation environments that require independent power supply or AC220V power.
Q8: Does the instrument require additional protective measures in -40℃ low-temperature environments?
A: The product standard operating temperature covers -40℃, but in extreme low-temperature projects, it is recommended to use heat tracing cables or insulation measures and confirm the stability of the power supply voltage.
