Flow Meters

　DMTFF

DMTFF Flanged Series Ultrasonic Flowmeter

Employing transit-time ultrasonic technologies for accurate liquid measurement
Signal quick tracking and self-adapting technologies allow system to adapt to different pipe automatically
Flanged connection makes the meter long-term reliability and stability
Suitable for commercial & consumable water measurement
Monitoring and detecting water leakage for the pipe system
Standard can be ANSI, JIS, DIN, GB and others
