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.
