This menu cell shows the current sonic velocity in m/s. If you move the cursor to this menu cell you will
note that it switches from the usual arrow ( ) to a question mark (?). This indicates that you can
increase the reading by pressing the [+] key for coarse adjustment or the [1] key for fine adjustment; or
reduce the reading by pressing the [-] key for coarse adjustment or the [2] key for fine adjustment.
Sonic velocity (Vs) adjustment is a diagnostic tool intended for our technicians or experienced users
only. Improper use will affect the meter accuracy.

FLOW DATA MENU ITEMS

This is a real-time (updated) flow rate display in current rate units (e.g., GAL/
MIN).
Linear fluid flow velocity in f/s or m/s depending on preferred units.
This is a real-time (updated) flow total display in current total units (e.g., KGAL).
Current liquid sonic velocity (Vs) in m/s. The Vs value depends on the liquid
and its temperature. This menu cell allows "fine-tuning" when highlighted.
Press [+] or [1] key to increase, or [-] or [2] key to decrease the reading.
CAUTION: Incorrect usage will result in reduced accuracy.
Xdcr signal strength (in mV). This is the amplitude of the transit-time receive
signals. Improper coupling, attenuative liquid or pipe could cause a low value.
Input Amplifier gain indication. Larger % indicates a stronger liquid signal.
This shows the current percent of aeration detected by the meter.
This letter code field shows the status of the meter's built-in alarms. A dash
indicates an inactive alarm. Letter codes reflect the following alarm condi-
tions:
S = Transducer Spacing Warning
E = Empty Alarm
R = Flow Rate Alarm (High or Low rate threshold exceeded)
F = Fault Alarm
A = Aeration Alarm
M = Memory Activated (Fault Suppressed)
K = Makeup Flag (May be Latched)
I = Interface Alarm
P = Pig Alarm (option)
Z = ZeroMatic signal fault
Flow Rate Simulator for calibrating external devices, etc. Highlight this item
then press the Right Arrow to enable numeric entry. Type desired simulated
flow rate. Be aware of the units prefix (K, M, etc.).
NOTE: AnCal remains active only while you remain in this menu cell.
Most positive expected flow rate for application (adjustable).
Most negative expected flow rate for application (adjustable).
