Dynameters Series DMTF-Ex ultrasonic flowmetes provide solutions for environment with explosion-proof requirements. Series DMTF-Ex consis of explosion-proof transmitters and explosion-proof transducers. Explosion-proof transducers consist of both clamp-on type and insertion type. The flow meters of the DMTF 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. Features: 1. Non-invasive explosion-proof clamp-on style transducers 2. Bi-directional flow measurement 3. Able to measure positive, negative and net total flow 4.
