Description
Our range of non-invasive
flowmeters utilises ultra-sonic technology for the accurate
flow measure-ment of liquids in full pipes.
The field mounted flow transmitter can be con-figured via
keypad without any additional program-ming devices and is
available as single or dual 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 meter 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.
- Low stocking costs, nearly all pipe sizes are covered
with only 2 types of sensors
