accurate liquid flow measurement from outside of a pipe. It utilizes
state-of-the-art technologies on ultrasonic transmission /receiving,
digital signal processing and transit-time measurement. The proprietary
signal quality tracking and self-adapting technologies allow system to
optimally adapt to different pipe materials automatically. The flow meters of the DMTF family are carefully designed so that their user-interfaces are self-explanatory and their operation is simple and easy. The unique clamp-on fixture design makes the installation very simple and no special skills or tools are required. Due to the non-invasive nature of the clamp-on technology, there is no pressure drop, no moving parts, no leaks, no risk of contamination, no risk of corrosion, no pressure dependency. |

The unique clamp-on fixture design makes the installation very simple and no special skills or tools are required. Due to hot-tapped mounting of insertion transducers, there is no ultrasonic compound and coupling problem; Even though the transducers are inserted into pipe wall, they do not intrude into the flow, thus, do not generate disturbance or pressure drop to the flow. Comparing with clamp on flow meter, the insertion (wetted) type has the advantage of long-term stability and better accuracy. |
