Page 9: 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. -
Page 10: Measurement Principle
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. -
Page 11: Typical Applications
Ultraflux offers a wide range of probes with different sizes and frequencies to be selected depending on the application and pipe diameter from 10 mm I.D. to more than 5 metres. -
Page 12: Probes, Supports And Accessories (See Also § 5)
/ consumption figures 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. - Page 13 If you are using intrusive/wetted probes, adjust the insertion depth and then the alignment or orientation of the probes for the same pair (to have parallel faces). L is the exact distance between probe faces’ and D is the projection part of L that is concerned with the flow: (L –...

Page 24: Probe Selection Criteria
5.1 Probe selection criteria: High frequency probes are small compared to lower frequency ones and are suitable for small pipes with thin pipe wall. They offer a higher Delta T accuracy measurement, insuring a good theoretical zero and better flow accuracy. But, at higher frequency, pipe or liquid conditions may influence signal quality: high signal damping or high distortion may have limitations and require lower frequency probes. -
Page 25: Probe Coupling
5.3 Probe Coupling : Clean the pipe at location for the probes: take into account the probe distance and consider the distance for the probe support or ruler. Simple preparation can be done with a paper tissue or old cloth piece. If the pipe is very dusty, use a metallic brush. -
Page 26: First Measurements
5.4 First measurements: (See § 6 / measurements in simple mode for more information) First operation is to connect the UF 801-P to the probes. Use the cable with a Y termination. If too short (large pipe, or for access to pipe work), use the extensions if supplied or ordered. -

Page 45: Examples Of Echoes And Criteria
9.2 Examples of echoes and criteria Experience shows that an echo shape is sharper when the distance between probes is 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 the pipe wall, and so the combination of received echoes. -

Then, a short check on site will confirm the data. -
Page 96: Sound Velocity In Fluids
21.3 Sound Velocity in Fluids : The speed of sound in a fluid is a physical characteristic of this fluid which may be linked to other characteristics, such as density (d), pressure (P), temperature (T) or the % of two or several miscible products, or with another magnitude having good analogy, like compressibility. -
Page 97: Applications On Petroleum Products
The water solid content has little influence: this table can be applied to raw or waste water. When compared with other fluids, the water temperature coefficient for C is positive up to 74°C. Beyond that, the water becomes a conventional product again. -
Page 98: Applications With Gas
This speed of sound varies also with the pressure and temperature, in a larger proportion compared to water. For instance: - Influence of pressure = + 1 m/s per bar for liquid butane and + 0.4 m/s per bar for diesel oil. - Influence of temperature = - 6 m/s per °C for butane and –...
