Description

Our range of non-invasive flowmeters utilises ultra-sonic technology for the accurate flow measure-ment of liquids in full pipes.

The portable device has been designed to meet the needs of the Service/Maintenance and Commis-sioning Engineer wishing to check the flow rate of liquids at different locations in the plant. The set-up of the unit is simple and user friendly in order to obtain the required flow information in minutes.

The measurement of flow is based on the principle that sound waves are influenced by a flowing medium. Measurements are made by penetrating the pipe with ultrasound and subsequently time differences, frequency variations and phase shifts of the ultrasonic signals are evaluated.

The ultrasonic sensors are clamped onto the outside of the pipe, thus eliminating the need to dismantle the pipework and interrupt the process. The unit can be applied to any type of standard pipe carrying clean or dirty liquids.

Advantages

- Low installation effort and costs
- Dual measuring mode (transit-time and doppler)
- Measurement is independent of fluid conductivity and
  pressure
- No pressure loss, no possibility of leakage
- Retrospective installation for existing plants possible
- No cutting of pipes necessary, no interruption of process, no
  plant shut down
- No additional fittings for maintenance required
- Hygienic measurement, no risk of contamination, suitable for
  ultra clean liquids
- No contact with medium, no risk of corrosion when used with
  aggressive media
- Cost advantages when used with large diameter pipes, high
  pressure systems, etc.
