Flow Meters

　DMTFC

DMTFC Insertion Series Ultrasonic Flowmeter

It utilizes transit-time ultrasonic technologies for accurate liquid flow measurement

Signal quality tracking and self-adapting technologies allow system to adapt to different pipe materials automatically

Insertion design guarantees no ultrasonic compound and coupling problems

No flow enclosure construction guarantees no disturbance or pressure drop issues
