Description
The EESIFLO 4000 Series range of non-invasive
flowmeters utilises ultrasonic technology for the accurate
flow measurement of liquids in full pipes.
The portable transmitter can be configured via the keypad
without any additional programming devices and is available
as single channel unit.
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 outside of the
pipe, thus eliminating the need to dismantle the pipework
and interrupt the process. The EESIFLO 4000 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 corrosion when used with aggressive media
- Cost advantages when used with large
diameter pipes, high pressure systems, etc.
