Precise and Versatile Measurement

The LFV Liquid Level Sensor delivers accurate level detection with 0.5% precision, suitable for a wide range of free-flowing liquids. Its vibrating fork technology ensures dependable operation regardless of liquid type, including corrosive and high-viscosity substances. Adjustable settings allow customization for process requirements, ensuring reliable data in challenging environments.


Built for Industrial Environments

Constructed from premium-grade SS 304, SS 316, and SS 316L materials, the sensor resists corrosion and withstands high process pressures up to 20 bar and temperatures up to 250C. The IP67/68 ingress protection ensures robust performance even in heavy-duty or wash-down situations. Its compact design and LED indication facilitate easy installation and monitoring.


Efficient and Maintenance-Free Operation

Designed for seamless integration, the LFV sensor offers relay output and analog signal compatibility. Its calibration-less feature saves valuable time during setup, while immunity to external vibrations guarantees stable operation. With remote and integral electronics options, implementation is straightforward in both new and retrofit installations.
