Flow This is a real-time (updated) flow rate display in current rate units (e.g.,
GAL/MIN).
Flow Vel F/S Linear flow velocity in f/s and m/s depending on preferred units.
Total This is a real-time (updated) flow total display in current total units (e.g.,
KGAL).
Vs m/s 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 the [+] or [1] key to increase, or the [-] or [2] key to decrease the
reading.
CAUTION: Incorrect usage will result in reduced accuracy.
Signal (mV) Xdcr signal strength (in mV). This is the amplitude of the transit-time re-
ceive signals. Improper coupling, attenuative liquid or pipe could cause a
low value.
Valc % Input Amplifier gain indication. Larger % indicates a stronger liquid signal.
Vaer % This shows the current percent of aeration detected by the meter.
Alarm Status 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
conditions:
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)
AnCal Flow Rate Simulator for calibrating external devices, etc. Highlight this item
then press <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.
HiFlow GAL/MIN Most positive expected flow rate for application (adjustable).
LoFlow GAL/MIN Most negative expected flow rate for application (adjustable).
