The DMTF wall-mount Clamp-on Ultrasonic Flow meter family provides abundant capabilities for 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 DMTF wall-mount Insertion Ultrasonic Flow meter family provides abundant capabilities for 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.
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.

DMDF1 Enhanced Ultrasonic Doppler Flowmeters measure solids-bearing or aerated liquids in metal or plastic pipe. Proprietary circuitry allows this instrument to operate with lower concentrations of suspended solids than any competitive Doppler flowmeter – expanding the instrument's range of applications and reliability. Clamp-on, or Insertion transducers permit the instrument to be installed in minutes without interrupting system pressure or flow. In addition, no pressure head-loss is created; therefore system pump horsepower requirements are reduced. The DMDF1 transmitter has a full keypad designed for simple field setup and application versatility. The two-line, backlit, alphanumeric display shows instantaneous flow rate and totalized flows in a variety of user selectable engineering units.
