The VSAN Non-Contact Radar Level Transmitter is an advanced microwave-based level measurement instrument designed to provide highly accurate, continuous, and reliable non-contact level measurement of liquids, slurries, and selected solid materials in industrial process applications. Utilizing advanced high-frequency radar technology, the transmitter measures the level without making physical contact with the process medium, ensuring exceptional reliability, minimal maintenance, and long service life even under demanding operating conditions.
Unlike conventional ultrasonic level transmitters, the VSAN Non-Contact Radar Level Transmitter uses high-frequency electromagnetic microwave signals that are largely unaffected by changes in temperature, pressure, vapor, dust, foam, condensation, humidity, and process gases. This makes radar technology an ideal solution for critical industrial applications where stable and precise level measurement is essential.
The transmitter continuously emits microwave signals through its antenna toward the surface of the measured product. These signals are reflected back from the material surface and received by the transmitter. Using advanced Frequency Modulated Continuous Wave (FMCW) or Pulse Radar Technology, depending on the model, the instrument accurately calculates the distance between the antenna and the product surface and converts it into a precise level measurement.
The VSAN Non-Contact Radar Level Transmitter is suitable for measuring a wide range of process media including water, wastewater, chemicals, acids, alkalis, solvents, petroleum products, diesel, furnace oil, edible oil, LPG, liquid fertilizers, slurries, powders, granules, cement, fly ash, and other bulk solids.
Manufactured using high-quality industrial materials such as SS316L Stainless Steel, PTFE, PEEK, PVDF, and corrosion-resistant antenna materials, the transmitter offers excellent resistance to corrosive chemicals and harsh environmental conditions. It is available with Horn Antenna, Lens Antenna, Rod Antenna, and Flush Antenna designs to suit different process requirements.
The transmitter provides a standard 4–20 mA analog output, with optional HART Communication, RS485 Modbus RTU, Profibus PA, Foundation Fieldbus, and Bluetooth configuration (model dependent), enabling seamless integration with PLC, DCS, SCADA Systems, Distributed Control Systems, and Industrial Automation Networks.
Designed for demanding industrial environments, the VSAN Non-Contact Radar Level Transmitter features a rugged IP66/IP67/IP68-rated enclosure, excellent EMC protection, superior vibration resistance, and an optional Explosion-Proof (Ex-proof) version for hazardous area installations.
Advanced digital signal processing incorporates false echo suppression, automatic gain control, temperature compensation, intelligent echo tracking, and diagnostic functions, ensuring stable and reliable measurement even in tanks with agitators, internal structures, vapor, foam, or uneven product surfaces.
The VSAN Non-Contact Radar Level Transmitter is widely used in Oil & Gas, Petrochemical Industries, Chemical Processing, Power Plants, Pharmaceutical Manufacturing, Food & Beverage Industries, Water & Wastewater Treatment, Steel Plants, Cement Plants, Mining Industries, Paper & Pulp Mills, Marine Applications, Storage Tank Farms, OEM Equipment, and Industrial Automation, where precise and maintenance-free level monitoring is critical.
With its high accuracy, non-contact operation, rugged construction, and intelligent radar technology, the VSAN Non-Contact Radar Level Transmitter provides an ideal solution for reliable industrial level measurement, process monitoring, and inventory management.
The VSAN Non-Contact Radar Level Transmitter operates on the Microwave Radar Time-of-Flight (TOF) Measurement Principle.
The radar transmitter continuously emits high-frequency microwave signals through its antenna toward the surface of the liquid, slurry, or solid material inside the tank.
When the microwave signal reaches the product surface, it is reflected back toward the antenna. The transmitter accurately detects the reflected signal and determines the distance between the antenna and the product surface using advanced radar signal processing.
Using the known propagation speed of electromagnetic waves, the transmitter calculates the distance between the antenna and the material surface. The level is then determined by subtracting the measured distance from the configured tank height.
An advanced microprocessor continuously performs digital filtering, false echo suppression, automatic gain control, temperature compensation, and intelligent echo tracking to minimize unwanted reflections from tank walls, nozzles, agitators, ladders, and other internal structures.
The calculated level value is converted into a standard 4–20 mA analog output or digital communication signal and transmitted to PLC, DCS, SCADA systems, or industrial controllers for continuous monitoring, inventory management, alarm generation, and process automation.
Since microwave radar signals are largely unaffected by vapor, pressure, temperature, dust, foam, and condensation, the transmitter provides highly accurate and reliable level measurement under challenging industrial process conditions.
The VSAN Non-Contact Radar Level Transmitter is extensively used for continuous level measurement in demanding industrial applications.
