Measurement Mode

Use this function to change between two measurement modes.

Option:

1 – 2

Caution!
The optimum measurement mode is automatically initialised during power on
and the Site Setup procedure. It is normally not required to manually change
the setting. See also the note below.

Factory setting:

1

Note:
Measurement mode1 – Trigger Mode:
The measuring device uses mode 1 for pipes in the nominal diameter range
DN50 and above.
Mode 1 weights the signal start of the ultrasonic signal received during anal-
ysis. This method has the advantage that both the transit time and the transit
time difference of the signal can be determined very precisely. The method is
reliable if the signal shape of the measuring signals are stable. This applies if
not a lot of interference is transmitted via the pipe and the application. On the
other hand, measurement mode 2 offers greater interference resistance for
applications with fluctuating reception signals or reception signals that have
high interference. If the measuring device indicates low signal intensity and a
fluctuating measuring signal for sound velocity and volume flow, this can be
improved by manually switching to Mode 2.
Measurement mode 2 – correlation mode:
The measuring device uses mode 2 for pipes with a nominal diameter
smaller than DN50. In applications in this nominal diameter range, ultrasonic
signals are naturally often superposed by interference signals (e.g. pipe-
transmitted signals). This interference can affect the stability of the measure-
ment or result in errors when determining the transit time difference. How-
ever, measuring mode 2 is immune to such interference to a large extent as
the correlation process generally has a high degree of interference resist-
ance. Due to it being somewhat less accurate when determining the transit
time, this method is normally not used for pipes with larger nominal diame-
ters. However, if stable measurement is not possible with measurement
mode 1, the measuring device can be switched manually to the correlation
mode. This often improves the situation. See also the description for “Meas-
urement mode 1” above.
