4.5.4 STRENGTH OF RETURN SIGNAL
This function allows the power of the ultrasonic echo recieved by the sensor to be
viewed. When the optimum signal strength is 90 dB the transmitter has a measuring
range of 7m for the remote version and 10m fo compact version. The strength of this
signal is maximum if the temperature of the gas and liquid are equal or the surface of
the fluid is calm.
This measure is useful to determine the best orientation of the transmitter
during installation. The best orientation is reached when the signal strength is
at the highest value possible.
