Description

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

The 19 inch rack mounted unit has been designed for permanent ins tallations in 19 inch control cabinets for applications where a non-invasive method of flow measurement is of paramount importance.

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. This measuring technique has no effect on the flowing liquid. There is no pressure loss in the pipe and no wear on components of the measuring device.

The ultrasonic sensors are clamped onto the outs ide of the pipe, thus eliminating the need to dismantle the pipework and interrupt the process . The EESIFLO 7900 Series can be applied to any type of standard pipe carrying clean or dirty liquids.

Advantages

- Low installation effort and costs
- 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
  ultraclean 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.
- Low stocking costs , nearly all pipe sizes are covered with only
  2 types of sensors
