01

OVERVIEW

What it does and why it is built this way

The FL-510 attaches to the outside of the pipe, so flow can be measured on an existing line without shutdown or leak risk. Two ultrasonic transducers send pulses with and against the flow; the difference in transit time gives velocity.

It is ideal for temporary checks, audit measurements and retrofit jobs where cutting the pipe is not an option.

  1. Two transducers clamp on the outside of the pipe.
  2. A pulse travels faster with the flow than against it.
  3. The transit-time difference gives velocity, with no cutting of the pipe.
