This function allows the power of the ultrasonic echo received 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.
