Echo size (D911)
The size of the echo returned from a surface depends on the surface range, gas composition and
temperature, transmitter performance, in-tank conditions (turbulence, presence of surface
foam, and draughts), and other factors.
The received echo strength may vary from pulse-to-pulse but monitoring the read-only
parameter Echo Size (D911) indicates the latest echo strengths.
The indicated value is an averaged percentage of the last five echoes, with 100% representing a
saturated returned signal.
