Ultrasonic Ranging System

 

Ultrasonic ranging systems include industrial and mobile robot guidance and solid or liquid level measurements in silos, tanks or wood-chip bins.

 

An ultrasonic ranging system mounted on top of a wood chip bin in Kelowna, B.C. Canada.

At each of the mills, there are bins that fill up with wood chips and sawdust. Mounted on top of the bins is a radio attached to a level sensor. Using DTMF tones, dispatch operators can interrogate each individual bin and receive a five/six tone reading (ie 6.8 which shows the contents are 6.8 meters from the top of the bin). The accuracy of the level sensor is one tenth of a meter. The range of the sensor is .1 meter to 15 meters.
