
It is also possible to force a compromise with Kh=Manual and value
depending on probes position: placing them just after a disturbance should
force a turbulent flow and a Kh around 1.08 ~1.10.
Case 3 : The UF 801-P is ON but does not display the flow:
If the UF 801-P displays
“
!!!!
” at screen bottom, this message means that there
is no valid ultrasonic signal or that the signals exist but the UF 801-P is not
configured or set to treat them.
Never forget the Echo display / Oscilloscope mode: it will give you the key for 95
% of encountered problems.

A common reason is because the echo is out of the receiver window because
of programming wrong pipe diameter, probes mode (/, V,N or W)…

Is the pipe full or partially full (not purged), or empty?

Excess bubbles? Pump cavitations? Water fall just upstream before the
pump such as inlet to a wet well…

Check connection to the probes and cables.

Is the pipe wall transmitting ultrasonic signals? (Concrete pipe / corroded
pipe …)

Is the installation mode suitable for conditions? > Try Direct mode (\) or
other sensors.

Are the probes correctly installed? > orientation, coupling … ) .
Case 4 : The UF 801 has no display or some of its functions are inactive.
If there is no display and no backlight:

Is the UF 801-P powered up?

Is the battery charged?

Switch ON/OFF after connecting the charger module as an external supply.

If nothing changes, there may be a hardware problem: contact Ultraflux or
his representative.
The UF 801-P is OK on the charger but still faulty on the battery (after
charging):

This may indicate a problem on the charge, from supervisor circuit or on the
battery itself (short battery life).

Same, refer to Ultraflux for service or control.
The UF 801-P keypad is inactive:

Switch OFF/ON and let the unit ON to discharge the battery and give a full
recharge.

If this problem persists, please contact Ultraflux.
Attention! After a very low battery state (or after have disconnected it), thus below
a low-low voltage threshold, it is necessary to reinitialize the internal clock. This
operation requires the Software and a PC connection.
