Measuring Principle
Two ultrasonic transducers, which are installed
under an angle to the flow axis, operate alternately
as a transmitter and receiver. The signals transmitted
through the gas accelerate in the direction of
flow and decelerate against the direction of flow.
The resulting difference in propagation times is calculated
using geometric variables to determine the
mean gas velocity. The cross-sectional area yields
the volumetric flow during operation. The measurement
result is not affected by the pressure, temperature,
or gas composition.
To increase the accuracy of the measurement, the
gas velocity is measured with multiple paths.

Path layout
The FLOWSIC 600 is designed as a direct path ultrasonic
meter without reflection points. This ensures
that contamination or changes in wall roughness do
not affect its measurement characteristics or longterm
stability. In addition the layout of the measuring
paths improves the signal-to-noise ratio.
Since the measuring paths are in one plane, the
influence of tangential flow constituents (e.g. swirl
flow) can be compensated.
Redundancy
The FLOWSIC 600 can easily be extended to a redundant
system. This can be achieved by adding one,
two, or four measuring paths in the free part of the Xshaped
measuring section and installing an additional
electronic unit at the meter body. As a result, the
main and the additional meter form a redundant
system which is integrated in one meter body.
Self-diagnosis
The electronics provide all the relevant parameters.
Deviations of key values (e.g. sound velocity, signal
gain, fault rate) are signaled immediately by alarm
messages. In this way, deviations can be identified
and removed before the measurement fails.
The MEPAFLOW 600 software allows you to access
the data online.
