Ultrasonic Analysis and Flowmeter
Foundation Field Device
Ultrasonic clamp-on analysis and flow measurement of liquids
Non-invasive, ultrasonic flow measurement is only an outsider method in
the technical sense:
Clamp-on ultrasonic transducers are simply attached to the outside of the
pipe. The practical advantages are obvious: no wear and tear by the
medium, no risk of leakage, no pressure loss and, above all, constant
The fact that non-invasive measurement technology could prove itself as a
standard method in many areas of the industry, is, if nothing else, a
credit to FLEXIM. Berlins ultrasonic experts have repeatedly set new
standards with their FLUXUS® flowmeters. Staffs at FLEXIM are
particularly proud of the pioneering work carried out during the transfer
of ultrasonic technology to non-invasive flow measurement of gases.
FLEXIM is the only provider to carry out clamp-on ultrasonic flow
measurements in high temperatures of up to 400 °C.
The 21 meters are Flexims Ultrasonic measuring systems for permanent
installation designed for concentration analysis process control -
especially in the industrial environment. In addition to the flow
measurement, the S721 flowmeter has a number of additional functions to
determine properties of the fluids and is available in different options.
Its non-intrusive measurement technology ensures a precise
bi-directional, highly dynamic flow measurement over a wide turndown
Enclosed in a robust metal field housing, the PIOX® S721 meters are
completely water-tight and designed for usage in rough environments. As
the transducers are mounted on the outside of the pipe wall in rugged
VARIOFIX mounting fixtures, the system does not suffer from wear and tear
or clogging, can't be a risk for leaks and will not cause any pressure
drops inside the pipe.
Due to their matched and paired transducers as well as the internal
temperature compensation (compliant to ANSI/ASME regulations), the
measurement system is drift free and zero stable ensuring accurate
readings. Moreover, as the transducer calibration data is automatically
loaded by connecting the transducer to the transmitter the set-up times
are significantly reduced. As of its exceptional dual-uP technology, the
high number of measuring cycles per second and the adaptive signal
processing, the PIOX® S721 meters produce stable and reliable measuring
results even under the most difficult conditions.
