4.4 NAVIGATING THE RUN MODE MENU PAGES
The display contains two lines of alphanumeric characters. Each line can be independently set to
display any of the seven operating parameters listed below.
Flow Rate – displays the current instantaneous flow value (e.g. 20.3 GAL/M). Note that reverse
flow is indicated by a minus sign preceding the displayed value (e.g. – 20.3 GAL/M).
Flow Total – displays the current flow total (e.g. 15030.5 GAL) Note: flow multipliers can be kilo
(K) or mega (M). The resolution of the displayed total can be set to show 1 – 3 digits to the right of
the decimal point. Totalizer will roll over to zero when the maximum count is exceeded.
Gain Level Percentage (Valc) – displays the signal amplifier gain level as a percentage value. The
higher the Valc value, the better. Valc values greater than 30 are generally considered good.
Aeration Percentage (Vaer) - displays the noise level generally associated with entrained air as a
percentage value. Lower values indicate less entrained air.
Signal Strength (mV) - displays the actual signal level in millivolts. Higher signal levels indicate a
good sonic coupling.
