(5) Make sure that the sensor is mounted in parallel with
the piping and that the mounting position is correct.
Then, turn the element holder clockwise until the
sensor is firmly fitted to the piping.
Stop turning the element holder where the transmitting
surface contacts the surface of pipe, and thus the
element holder will not rotate.
Do not turn it excessively.
