Description

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

The field transmitter EESIFLO™ 8000 Series has been designed for permanent installations in potentially explosive atmospheres and for field applications with harsh environmental conditions . The opening of the enclosure is not required for instrument set-up and operation and without the necessity of a separate hand-held remote control or laptop com-puter.

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 mea-suring 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 out-side of the pipe, thus eliminating the need to dis-mantle the pipework and interrupt the process . The EESIFLO™ 8000 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 ultra clean liquids
- No contact with medium, no risk of corros ion when
  used with aggress ive 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
- Transmitter and sensors can be located in hazardous
  areas Zone 1 and 2
