See 1.4 and our NT122 for general purpose recommendations. Most of the following rules are common sense: Easy access and the possibility to have the UF 801-P at a convenient height allow easier diagnostics. Check that you have a sufficient space to install probes (including support?). -
Page 25: Probes Coupling
In case of turbulent to laminar flow transition risk (very rare with water), we give some complementary recommendations in Expert menu. 5.3 Probes Coupling : Clean the pipe at location for the probes: take into account the probe distance and consider also the distance for the probe support or ruler. This cleaning can be done simply with a paper tissue or an old cloth piece. -
Page 26: First Measurements
To obtain a positive flow display, connect cable N°1 to upstream probe and cable N°2 to downstream one. As soon probes are connected and UF 801-P device correctly parameterized, the flow reading should be available. To check that conditions are OK, or if no result, we duly recommend using the echo display menu to have a look on ultrasonic signals. -

The UF 801-P time measurement resolution is smaller than 0.05 ns. Probe time accuracy depends on their frequency. For instance, SE 1586 can offer better than 0.1 ns. But, if this Delta T is very small and if actual flow zero has not been checked, you must question yourself about the actual accuracy limits.

As long this « Auto Zero” message is displayed, the UF 801-P is in progress and acquires this “Delta To” offset. When finished, it automatically places this value at” Delta_To” line. Attention ! This value is tight to actual measurement point. As an approximate, it can be considered as attached to a same probes set, but, if the next application is very different, please reset it to zero in probes menu. -
Page 38: Response Time / Flow Display Filtering
A high filter value gives very stable flow readings. But, if the actual flow changes suddenly (when starts or stops of a pump for instance), the UF 801-P flow display will be in late and not realistic for some time. The Delta V Filter parameter permits an efficient compromise:... -

Page 45: Examples Of Echoes And Criteria
9.2 Examples of echoes and criteria Experience shows that an echo shape is more propitious when distance between probes is a little bit shorter than the requested distance. A larger distance has the contrary effect. This is due to the total beam surface in comparison with multiple echoes in pipe wall, and so the multiple combination of received echoes. -
