the top of the tank down to the surface of the liquid in the tank. The TLM150 then measures 
the time it takes this pulse to travel down to the surface of the liquid, be reflected back up, and 
then be received back at the sensor component. Using the speed of sound, it uses this time to 
calculate the distance between the face of the sensor component and the surface of the liquid 
(or the tank bottom if the tank is empty). The cone width of the beam transmitted by the
