Operation:

The WL705 sensors use ultrasonic sound waves to determine the distance from the face of the sensor

to the surface of the water by timing how long it takes the signal to return. An internal temperature

sensor automatically compensates for the temperature related variation in the speed of sound and a 15-

second averaging time reduces the affects of turbulence in the water. Note that the sensor must be

powered for 15 seconds for the output to stabilize.
