RF Admittance Level Sensor — High-Precision Level Measurement Solution
Shenzhen Soway Tech Limited (Soway) has independently developed the RF Admittance Level Sensor (SFC5 Series), which utilizes advanced RF admittance measurement technology to achieve both continuous liquid level monitoring and point-level alarm control. This series is widely applied in industrial automation, chemical, pharmaceutical, and oil & gas storage industries, offering high accuracy, anti-build-up interference, and exceptional reliability.
Point-Level Measurement
The SFC5 Series provides point-level detection solutions suitable for precise control of liquid level switch points:
RF admittance measurement principle eliminates measurement errors caused by electrode build-up
Applicable to water, oil, viscous liquids, and chemical liquids for level switch alarms
No moving or elastic parts, providing strong impact resistance and easy maintenance
Continuous Level Measurement
The SFC5 Series is the core solution for continuous level measurement:
Based on RF admittance measurement technology, it provides real-time liquid level monitoring
Supports multiple output options: 0.5–4.5V analog signal, 4–20mA current output, and RS485 Modbus digital communication
Probe length customizable, with a measurement range of 80–3000mm
Available in integrated or split probe designs suitable for different temperature environments (–40℃ to 200℃)
Continuous level measurement is widely applied in water treatment, oil tanks, chemical reactors, and viscous liquid storage.
