UF 801-P COMPLIANCE:
1-Safety Precautions:
When using this UF 801-P with probes or accessories, please respect site safety
regulations. Access to pipe work very often requires removal of protection or lagging.
Pipes can be hot or may possibly contain corrosive or toxic liquids or gases: ensure
always you use PPE (Personal Protective Equipment) i.e. helmet, gloves, glasses…
Particular attention is required when a flow test is in an ATEX Ex classified area: please
respect site instructions and ask for permit where required. Probes, connection and
instrument handling… could cause sparks, providing a source of ignition for flammable
or explosive mixtures.
Always keep the instrument in good condition.
Charging the UF 801-P batteries requires significant current charging, involving a mains
power connection. Even with the best built-in safety components to prevent from over
voltage or other external reason, over charging may cause over-heating…. Avoid
leaving the device connected to the charger longer than necessary, without checking or
securing these conditions.
2-Conformity to EC Norms:
All equipment is CE certified .
UF 801-P is typically specified as IP67 and has been successfully tested IP68 under 2 m
of water for 8 hours. However, it is better to prevent it from immersion or to provide
heavy duty protection if the immersion risk is great or the humidity is high.
ATEX certification can be delivered for the relevant probes and standards, when
required. All equipment will be labeled accordingly. In the absence of the relevant
marks and attached certificates, do not consider the instrument so certified!
Main Applicable Standards:
• Concerning high voltage human safety risks :
UF 801-P: N/A – Only low voltage (< 60 V).
Charger: 100-240 V AC : conforms to UL & CE Directive 73/23/CE, Rev.
2006/95/CE…
• Concerning EMC : Directive 91/157/CE
• Concerning tightness ( IP ) : EN 60529
• Concerning ATEX : Directive 94 / 4 / CE and Directive 99/92/CE (*)
• Recycling & Environment Protection: ISO 14001 / DEEE > 13/06/2005 in
France
(*) UF 801-P would only be considered as associated to Ex mb IIC T6 with
relevant transducers and attached cables. The Converter would have to be in
the safe area.
Please refer to official documents / conformity certificates

NT228B GB2 5
3- Other Certifications:
All equipment is flow tested before delivery, and compared to a standard.
On request (but not free of charge), the instrument can be delivered with a calibration
certificate. Contact sales for further details.
4-Warranty:
Please refer to the sales contract for terms and conditions.
This Warranty supposes that this instrument is used for the purpose of its design and
has been operated according to the instructions given in this manual. Any maintenance
operation or component replacement must be done by an Ultraflux authorized agent.

3.1 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 channel version that offers double menus and
multiplexed resources. We will consider mainly UF 801-P except some points as
mentioned in §9.
Both versions 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. It displays the
following results:
•The flow velocity
•The volume flow
•The totalized flow
•The sound velocity
•Process / fluid data and user information.
The correct probes must be selected with respect to pipe diameter, pipe or fluid
conditions, pipe wall temperature etc.
> Please contact Sales for further information.
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 wall
thickness.
UF 801-P can operate in different languages. This selection is made in the
Configuration Menu.
A short form guide NT 227 is available. This NT 228 manual is the reference
manual.
It is possible to customize the UF 801-P by choosing your input / output modules
at order stage. Basically, UF 801-P is equipped with one 4-20 mA output, 2 Relays
and one RS232 port.
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. This can reduce the number of records without loosing information.

NT228B GB2 10
3.2 Measurement Principle
As stated above, please refer to our NT122 didactic handbook on the included cd.
It contains useful information on the measurement principle, ultrasonic wave
transmission, hydraulic conditions, flow profile and Reynolds Number
The first condition to measure flow is that the fluid can transmit ultrasound at the
chosen Frequency: it must not be too viscous or include too many particles or gas
bubbles that create a barrier or disperse the sound energy.
Contrary to the electromagnetic principle, conductivity has no influence.
So, with two probes with following installation:
Always keep in mind the flow integration and flow results depend on the flow
section and the flow profile. Choose the best probe arrangement and location to
minimize external influences. Fully developed and stable hydraulic conditions are
preferred measurement locations.
Always keep in mind that the physical measurement is based on the time and
Delta t result. Lower Delta t requires more attention to probe choice, installation
and zero setting …
The two probes are used alternately as
an emitter and receiver: the difference
between the speed of sound and the
flowing fluid velocities creates a time
difference between upstream and
downstream sound transmissions.
UF 801-P, with its dual 32 bits
processors and DSP PC Board,
performs a digital signal shape
analyse, offers a very high resolution,
accurate transit time and Delta t
measurements, the key of high level
reliable results.
Delta t = tBA - tAB (nanosecond)
VUS = (L2/2*D)*(Δt/tAB*tBA) (m/s)
And, with Kh = VUS / Vs(S = section)
Q (Flow) = S * Vus / Kh (m3/h …)
Volume = Q * Time (m3… )
