The ULP has been designed to avoid any mechanical
parts to maximize reliability and minimize maintenance.
The transducers communicate between themselves two
by two using ultrasonic range waves. Each pair of trans-
ductors calculates the signal delay and get information
about both wind direction and wind speed.
