Siemens LR250 l.o.e. in Steam Environment

Using LR250 to measure levels in tanks, but periodically loosing echo, shows as l.o.e. on unit display, and signal goes high, to trigger alarm.

Are there any settings for helping the LR250 cut through the steam? I read about the confidence and threshold settings, but I don't think I understand it fully.
Radar Level Measurement seems to be the new improved modern way - but does have disadvantages!

Minor adjustments may help differentiate echoes from differing densities, but loss of echo, however, temporary appears as a process fault.

Using alternative methods of water Level Measurement may be the long term answer.
