RADAR LEVEL SENSOR
LVRD500 Series
Non-Contact Measurement
Continuous Level Measurement
Pulse Radar Measurement Range: 0.254 to 30 m (10" to 100')
Simple Pushbutton Calibration
Communications Standard
The LVRD500 Series comprises low-cost radar sensors for continuous level measurement.
This series, a logical extension to the ultrasonic sensor series, is designed for applications
requiring non-contact liquid level measurement, in which ultrasonic level measurement
is not acceptable.
The LVRD500 Series radar technology can be adjusted for variables such as materials to be
measured, vessel configuration, and system interface. These sensors are ideal when vapor,
dust, or a foaming surface prevents ultrasonic-wave measurements.
