General information

Two sensor types are available with the DFX meter:

Series DT9 clamp-on, non-intrusive sensor is recommended for use on most pipes, constructed from metal or plastic. The DT9 is rated to Type 6 (IP67) and has the ability to work with temperatures up to +200 ºC (+400 ºF).

Series DP7 hot-tap insertion probe sensor is available for installations on pipe systems that do not permit ultrasound penetration. The DP7 inserts into the pipe wall and directly contacts the flowing liquid

Measuring principle

Ultrasonic flow meters


Ultrasonic flow meters

Ultrasonic signals are alternately sent in and against the flow direction. Ultrasonic energy bursts are transmitted and received via well-defined paths across the flow stream. The velocity of the flow is accurately measured by the difference in the arrival times of signals from the upstream and downstream transducers. The transit time difference ( Δt = t 2/1 – t 1/2) determines the average flow velocity.
