Basically, we practice only a dry calibration. Its reliability is sufficient for a
standard use. Moreover, it offers a very high repeatability when redoing the same
probe installation.
Example of installation:
Here is a dual pipe installation.
SE_1586 probes are in V reflex mode.
Application is ultra pure water.
Purpose is to calculate from flow and return
the real production / consumption
.
3.4 Probes, Supports and Accessories (see also § 5)
The UF 801-P / PB accepts all standard or special transducers from Ultraflux
catalogue with frequency from 200 KHz up to 4 MHz. Most of them, for portable
use, are clamp-on with fast connection, but UF 801 can accept insertion or wetted
models as well.
Please, refer to the probe data sheet for specific technical characteristics.
UF 801-P menu lists the standard available probes:

Clamp-on probes are referenced SE . Each reference is attached to an
internal table with the probe frequency, the beam angle and the dead time
in the wedge.
 Insertion probes or wetted probes are referenced SM . The attached
table considers only the crystal frequency and the dead time in probe face.
If probe has a built-in angle, only L & D installation distances describe the
exact installation.
 It is also possible to enter special probe SA or SB (clamp-on or wetted).
The selected pipe section to install the probes should allow for the best
the straight lengths , mainly upstream from the probes, but also downstream, in
order to benefit from a predictable and stable hydraulic profile.
We usually consider 10 pipe diameters upstream, and 3 downstream, as
acceptable conditions. Larger distances are preferred, if possible. Consider these
distances with respect to the upstream disturbance: a divergent is typically worse
than a convergent flow!
To avoid deposits or accumulation of gas, planes close to vertical (+/- 15°) must
be avoided. So, install the sensors in a horizontal plane (unless the conduit is
vertical!).
