Make decisions with confidence. The CR-S delivers the precision, reliability, and flexibility needed to help operators better monitor inventory, optimize processes, and reduce uncertainty.
Up to 394 ft. of reliable measurement.
Monitor tall silos, deep tanks, and large storage vessels with confidence. Extended measuring range allows a single sensor to handle applications that would challenge traditional level technologies.
Swivel flange options available.
Help simplify mounting and alignment, making it easier to position the radar beam perpendicular to the measured media for optimal performance.
Integrated air purge features on select models
Keep lens clear of dust, buildup, and material accumulation without frequent manual cleaning to keep readings accurate.
Millimeter wave technology, 3º beam angle, and ±2 mm accuracy
A high signal-to-noise ratio helps ensure strong echoes and reliable measurements, and the smaller blind zone enables measurement closer to the sensor. The focused 3° beam angle and ±2 mm accuracy help deliver dependable level data, even in challenging installations.
