Réference : DUS-TT-F Gold

The most accurate flowmeter on the market
Accuracy: 0.5%

Series DUS-TT-F Gold wall-mount Clamp-on Transit Time Ultrasonic Flow Meters provide abundant capabilities for accurate liquid flow measurement from outside of a pipe. It utilizes state-of-the-art technologies in ultrasonic transmission receiving, digital signal processing and transit-time measurement. The proprietary signal quality tracking and self-adapting technologies allow the system to optimally adapt to different pipe materials automatically.
The flow meters of the DUS-TT Gold family are carefully designed with their user-interfaces self-explanatory and their operation simple and easy. The unique clamp-on fixture design makes the installation very simple, requiring no special skills or tools.
Due to the non-invasive nature of clamp-on transducers, there is no pressure drop, no moving parts, no leaks, and no risk of contamination or corrosion.

Comparing With other traditional flow meter or ultrasonic flow meter, it has distinctive features such as high precision, high reliability, high capability , the Flow meter features other advantages:

1. With ARM COMA chip, low power consumption, high reliability, anti-jamming and outstanding benefits.

2. User-friendly menu designed. Parameters of pipe range, pipe material, pipe wall thickness, output signals, etc can be conveniently entered via the windows. British and Metric measurement units are available.

3. Daily, monthly and yearly totalized flow: Totalized flow for the last 64 days and months as well as for the last 5 years are may be viewed. Power on/off function allows the viewing of time and flow rate as power is switched on and off 64 times. Also, the Flowmeter has manual or automatic amendment during offline sessions.

4. With the SD Card, 512 files can be stored; the time interval can be within 1 second.

5. Parallel operation of positive, negative and net flow totalizer with scale factor and 7 digit display. Internally configured batch controller makes batch control convenient.

6. The flow meter ensures the higher resolution and wider measuring range by the 0.04nS high resolution, high linearity and high stability time measuring circuit and 32 bits digits processing program.
