OTT RLS – Radar Level Sensor

OTT RLS is a non-contact radar level sensor with pulse radar technology. The OTT RLS offers a large measurement range with a small blanking distance and narrow beam width and it easily connects to most data loggers. The RLS has extremely low power consumption and is ideal for remote or solar powered sites.
