Overview
UF 801-P
is a high performance ultrasonic portable flow meter for closed pipes
and conduits.
UF 801-PB
is the dual pipe or channels version that offers double menus and
multiplexed resources. We will consider mainly UF 801-P except some points as
mentioned in §9.
They both use ultrasonic signals between two aligned probes arranged on one or
two paths, to integrate a flow section.
>
See measurement principle on 2.2 or better NT122.
UF 801-P
performs a very accurate time of flight measurement on these
ultrasonic pulsed signals and, after calculation from entered data. I displays the
following results:
The flow velocity
The volume flow
The totalized flow
The sound velocity
And much more information that you will discover.
For this, the
correct probes
must be selected with respect to pipe diameter, pipe
or fluid conditions, pipe wall temperature and so one.

As the
UF 801-P is a portable unit
, it is usually powered from its internal
battery. It is delivered with an external charger that requires an external supply to
be connected to Mains from 100 to 240 V AC / 50 or 60 Hz, by using the suitable
cable and connectors.
UF 801-P with its accessories
is presented in a robust carrying case. See
picture.
With an optional probe (
SE 1701
), UF 801-P is able to measure pipe walls
thickness.
UF 801-P
can operate in different languages. This selection is done in the
Configuration Menu.
You can refer to our short form guide NT 227. This NT 228 manual is the
reference manual.
It is possible to customize your UF 801-P by choosing your input / output modules.
Basically, UF 801-P is equipped with one 4-20 mA output, 2 Relays and one RS232
port.
As the
UF 801-P
is a self operating unit, it has an integrated data-logger able to
record up to 135 000 measured flow values with the time and date, or, with 14
simultaneous values, up to 36 000) records.
Each record can be the average or min/max peak value during the recording
period. Thus, it is possible to do less often records without loosing information.
