Gas phase compensation with reference signal
This type of gas phase compensation needs an artificaial reference echo at a definite
distance from the process connection. The reference signal must always be above the
maximum level. The position of the reference echo depends on the pressure of the gas
phase. The device uses this echo shift to calculate the correction factor for the distance
measurement.
