The unit is designed to withstand submersion during surcharge conditions.

  • Page 10: Theory Of Operation

    The water level is measured using an ultrasonic pulse echo sensor. Two models are available, a standard range ® 1,75 m and a long range 5,75 m sensor. The sensors can be attached to the RAVEN-EYE sensor body using specific mounting hardware. For both sensors a sound pulse is sent to the water surface and a portion of the signal is returned to the sensor.
