Continuous level measurement devices, instruments and sensors provide precise, reliable readings

Ensure consistent material feed

Prevent bin overflows, plugged chutes, and empty bins with Thermo Scientific™ Ramsey™ level sensors. Our continuous level measurement devices penetrate dust, steam, vapors, and other harsh environmental obstacles to provide precise, reliable readings. Microwave or nuclear point level detection and control switches monitor the silo or bin level above the weighfeeder. We offer microwave-based, non-contact flow sensors for monitoring solid flows in pipelines, ducts, air slides, and at transfer points.
