The RF Admittance Level Sensor from Shenzhen Soway Tech Limited is a high-precision level measurement solution specifically engineered for applications where installation space is limited and process conditions demand excellent stability. Designed around advanced RF admittance technology, the SFC5 Series achieves accurate, repeatable measurement while effectively eliminating errors caused by material buildup on the probe.

The compact structure of the RF Admittance Level Sensor allows easy installation in confined tanks, narrow pipelines, small vessels, and equipment with limited mounting positions. The integrated electronic housing and streamlined probe design make it ideal for use in OEM machines, chemical dosing systems, mobile equipment, and small industrial tanks where traditional sensors cannot fit.
Despite its compact size, the sensor maintains strong mechanical durability, high impact resistance, and stable signal output across a wide operating range, ensuring dependable performance even in tight spaces.
Anti-Adhesion Performance — Minimal Effect from Coating or Buildup
The SFC5 Series is built on true RF admittance measurement principles, enabling the sensor to simultaneously evaluate capacitance and resistance.
This unique approach ensures:
Strong anti-coating capability
Accurate measurement even with viscous or sticky media
Immunity to probe fouling and buildup layers
Unlike traditional capacitive sensors, which often drift or fail when coated with oils or viscous liquids, the RF Admittance Level Sensor keeps performance stable thanks to its phase-tracking technology and optimized RF frequency (15–400 kHz). As a result, users benefit from consistent reliability, reduced maintenance, and worry-free operation in harsh or buildup-prone environments.
The RF Admittance Level Sensor from Shenzhen Soway Tech Limited delivers accurate, reliable, and stable liquid level measurement even in challenging environments where coating, viscous media, or limited installation space pose difficulties for traditional sensors.
With advanced RF admittance technology, multi-signal output options, and robust industrial-grade design, the SFC5 Series is an ideal choice for modern automated control systems across multiple industries.
