UDM 300E from SebaKMT (Germany) is advanced ultrasonic technology for mobile and highly accurate flow measurements.

Piping diameters and matching pair of sensors:

UDM 300 set with 1 MHz sensors for pipeline diameters from 80 mm to 400 mm - ordered price.
UDM 300 set with 0.5 MHz sensors for pipeline diameters from 400 mm to 3'100 mm - 13530,- EUR with VAT.
UDM 300 set with 2 MHz sensors for pipeline diameters from 25 mm to 400 mm - 11145,- EUR with VAT.

 Special features: 

• Very high measurement accuracy (also bidirectional)
• Accurate even at extremely low flow rates (e.g. minimum night flow)
• Ideal for temporary measurements (up to 7 days with additional rechargeable battery)
• Sensors with IP 68 protection (test conditions: 3 months / 2 bar)

The UDM 300 is an extremely robust and easy-to-operate device for monitoring flows temporarily. The non-invasive installation of sensors on the outside wall of the pipe takes only a few minutes, yet the recorded data have a very high accuracy and reproducibility.

The UDM 300, which is manufactured in Germany and is CE certified, combines advanced ultrasonic technology with a robust design and very easy operation. 

The UDM 300 is an extremely robust and easy-to operate device for monitoring flowstemporarily.
The non-invasive installation of sensors on the outside wall of the pipe takes only a few minutes, yet the recorded data have a very high accuracy and reproducibility.
The standard 1 MHz sensors of theUDM 300 allow high-quality measurements even on pipes made of difficult material (e.g. glass-fibre reinforced plastic or reinforced concrete). We offer our extremely powerful 0.5 MHz sensors as an option for pipe diameters up to 3,100 mm.
The ability of the UDM 300 to measure bidirectionally and to detect very low flow rates makes it an ideal device for identifying potential leaks using volume comparisons. Precisely because of its high resolution in the low flow range, the UDM 300 is also used to determine the minimum night flow of isolated areas of the network (called DMAs).
